Quantum mechanics forbids us from measuring the universe beyond a certain level of precision. But that doesn’t stop us from trying. And in some cases succeeding, by squeezing the Heisenberg uncertainty principle to its breaking point.

Correction: The wonderful folks at LIGO reached out and let us know that they *have* in fact used squeezed light in the 2019-2020 observation run. Congratulations to LIGO for yet another incredible innovation and our apologies for the error!
I Think they have also used the "stretched light" as well.
That was a misleading title. Nothing was "broken" because the principle remained intact, as expected. Interesting how LIGO resolves greater detail by narrowing the uncertainty of one parameter as the other -- and less important -- increased. But, nothing was *broken*.
Awesome. Thanks for the excellent video. Big fan of what y'all do.
My GF gave me a light squeeze just the other day. I was as happy as LIGO!

Star Trek has Heisenberg compensators as part of the transporter. When Mike Okuda was asked how they work, he replied, "Very well, thank you."
And quantum discriminator is in every class room.
My goodness, you've got a good memory.
Only tng.
That's what I loved about classic Star Trek. With a little bit of scientific knowledge you can piece together what everything actually does, at least at the high level, and it's all extremely internally consistent. Of course we don't know how it works, but we know why it works.
In the reboot star treks everything is powered by mushrooms, fight scenes, lots of crying and advanced forms of woke.
It will never cease to amaze me how these people find solutions for problems they derived from asking questions I couldn't even imagine.
Give yourself enough time in a room with other inquisitive people and you'll start coming up with a few. Sincerely, a physicist.
I think it’s either unfathomable or it frightens a lot of certain types of people that there are others soooo much more clever than they are.

Hold on to your interferometer
@@wolfboyft yeah world peace is a pretty big button issue
@@DjSapsan haha these two channels share a lot of their fans
Awesome episode as always!
Quick side-note from someone that works at LIGO here.
We set the interferometer up such that the waves don't actually destructively interfere completely, only partially.
That is because a completely destructive interference makes the detector the least sensitive to small changes in the differential length of the arm (That would be the bottom of a sine wave on an intensity vs differential arm length plot).
Keeping it at the 1/2 max intensity would make the light output to change the most with differential length (right between bottom and peak of sine wave) but it would also introduce too much noise (not sure on the specifics there).
So the interferometer is kept at about 1/4 or so of the maximum intensity :)
Nice remark! It looks like you heterodyne a signal at the half of its amplitude. Makes sense!
Cop pulls Heisenberg over and asks, "Sir, do you know how fast you were going?"
Heisenberg replies, "No, but I can tell you exactly where I am."
The cop responds, "You were going precisely 102 km/h"

You went to grab a drink and a snack.
Great video. I'm not sure I would call it "breaking" but rather simply "using" the Heisenberg Uncertainty Principle. It is more of a celebration of how to exploit it technologically in novel ways than a demonstration of pushing it beyond physical limits.
Yeah, I was thinking the same thing. What they're calling 'breaking' is actually the uncertainty principle in itself.
@@rohanmeerhaeghe3621 It has barely just begun....and I'm holding on with baited breath.....because I've never been so nervous about some of the things I have theorized predicted, I'm worried about those things being correct.....well I'm not sure I necessarily feel bad (I might feel thrilled/vindicated) however.....the things/new technologies that could arise.....just um...yup nope...

He is taking advantage of "clickbait."
Matt will always be able to end an episode with "spacetime"
In spacetime XD
Hm, what's the complementary variable to the uncertainty of Matt saying "spacetime" at the end of the episode?
Of course. That's called the O'Dowd Certainty Principle.
He's had to reach for it a couple times, but most of the time it's pretty smooth. sometimes downright clever.
Once there was an episode where I got upset, because it did not end with "spacetime".
But after listening carefully, I found out it was a genius: "blah blah blah's pace time" (where the blah was real talk)

Effortlessly he glides aside and back again without even blinking. Any river-dancer could learn a thing or two from this guy!

A non-linear crystal acts basically like a symmetric transformer in professional audio applications. It regularly amazes me how my knowledge of audio engineering helps me wrap my head around quantum phenomena.
Totally. When I was a little teenager I gave up understanding quantum, got into optics and audio, and when I finally came back to quantum I could understand a ton of it.
Matt, I started watching PBS Spacetime at the end of my junior year/start of my senior year in high school. These videos played a large role in my decision to study physics for my bachelor degree.
Earlier this year, I started my PhD in theoretical atomic physics. When I saw the title of this video, I knew it had to be on squeezed quadratures. This summer I'm working on research about squeezed spin quadrature! So I just wanted to say thanks for the awesome lessons, and I look forward to many more.
I think 🤔 the title is misleading. What you are proposing is not breaking the principle. Breaking the principle would be able to set up a measurement where ∆x∆p

9:35 is a funny one; the increased certainty in the phase causes increased noise in the amplitude. You have to be careful to understand what is meant by "uncertainty" else it sounds like magic.

What a coincidence, i am in 11th grade and yesterday my teacher was explaining heisenberg principle.
I needed an more neat explanation and now here is your video.
Unfortunately, most teachers don't understand anything about quantum mechanics cus they didn't learn it in school. Most are just regurgitating facts without Understanding.
@@bigsmall246 thankfully mine was different since he actually had a PhD in it! He did a very good job of summarising quantum weirdness when the class had questions, but without being sidetracked too long and went back to what the curriculum said he should be teaching. Also he shared lots of cheesy physics jokes, had a few such XKCDs printed out on his wall, and put Futurama on in his last day before moving to another school at the end of the year. He was awesome.
@@kaitlyn__L that's great! But sadly teachers with enough interest to get a PhD exist mostly only in universities.
@@bigsmall246 yeah, I was very lucky that he took a secondary school teaching job. Especially since he moved there when I started and he left the year I finished - his next job was as a department head and he lamented to me that he probably wouldn’t actually have a class there. But the pay was too good to stay.
All rather serendipitous. I do often wonder if I wouldn’t have fallen in love with physics were it not for him, especially as he was actually my science teacher (later physics teacher in the final years when they were separate) in about half the years, but there were enough of them in the school that we could’ve had a totally different one each year like I did maths teachers.
I hate to be "that guy" but unfortunately this video's misleading. Nothing shown here "breaks" the uncertainty principle. Actually, everything about squeezed light only exists precisely because the uncertainty principle is not broken. This video is the baitest of clicks.
The shortest measurable amount of time is the gap between when the light turns green and the cab driver behind you beeps the horn. Rip Terry Pratchett.
A really cool example of how complementary variables show up in real life is happening right here on CZcams!
Consider watching your favorite physics channel at 2x speed. The reason Matt doesn't sound like a squirrel when you're doing that is because CZcams tries to keep the frequency information of the audio at each instant along the video the same even though the video is going twice as fast. To do this, you need to know the frequency content of the audio at each instant, BUT you can't get frequency information from just a single audio sample, that's just a point. Instead they try to take as short an audio sample as possible, which is called a "short Fourrier transform" (I think) of the audio with a small window. The smaller the window, the more the sample represents a single instant in time, but also necessarily has more uncertainty in the frequency content of that window. The longer you make the window, the more frequencies you can notice, but the less those frequencies correspond to a single instant.
To my mind it is the simplest example of complementary variables that I can think of.
Indeed, and you can hear this in various electronic albums of the late 90s and early 00s, when pitch shifting while preserving speed, and speed shifting while preserving pitch, were new and all the rage. The first example that I always think of is Fatboy Slim’s track with “check it out now, the funk soul brother” at the end. Past a certain amount of slowing down you can actually hear the gaps between the tiny snippets of audio.
Nice
Now I'm waiting to see a SmarterEveryDay video where Destin is standing in a lab with another guy and asks him, "Wait, so you're telling me that this clock right here, and that clock right there, are holding each other's quantum-entangled atoms?" and the guy casually tells him "Yep, that's right."

Engineers for things like LIGO are so much more impressive than they often get credit for. This is astounding.
Stay well out there everybody, and God bless you friends. :)
And that's why we all know where Space Time will upload... but never exactly when.
And if you would only subscribe to spacetime, the likelihood of watching another video at the time spacetime releases would come down, but also the likelihood of being on CZcams while they upload would come down at the same time XD

This is actually the principle of balanced (symmetric) signal transmission, aka common mode rejection, as used in any CAT or microphone cable with paired wires. Engineers to the rescue (and thanks for acknowledging them, Matt!!)
OK, that concept of squeezed light using entangled photons at the LIGO is officially the coolest thing I've heard in a long time. Damn that's clever.

@authorization batman Yeah, being disabled is great. It's all fun and games with no downsides at all!
I just wish that more people would communicate that the Uncertainty Principle isn't some mystical quantum phenomenon, but is in reality just a natural consequence of working with waves.
Simply communicating to people that it just one of the limitations of the mathematics of waves would dispel so much confusion people have about quantum physics.
In defiance of Heisenberg’s uncertainty principle, Chuck Norris can know a particle’s position and velocity at the same time. This is because particles stand where Chuck tells them to, and stay there until he tells them to leave…..if they know what’s good for them.
On avg, yes, but individually they arrive at slightly different times… 😬🤔
I thought you’re going to speak about weak measurements. You should definitely do an episode about that, it’s a really interesting development. And if we’re already with Yakir Aharonov, an even more fascinating idea for an episode is the two-state vector formalism, that truly is mind breaking and I’ve had the honor of hearing a lecture about it from and speaking with Avshalom Elitzur.

Lmao your username and pfp.
I'm learning things from this channel I would have had no idea of otherwise. Love it. The principles behind LIGO are really fascinating. Entangled phases - brilliant!
My God this was an awesome episode! Thanks guys!!
I can't resist this classic here. Education is one's progression from cocksure ignorance to thoughtful Uncertainty!
Rather than "Breaking the Heisenberg Uncertainty Relation", what you have described is 100% "Obeying the Heisenberg Relation". I like to think of the Uncertainty relation as a mathematical theorem derived from the Dirac quantization condition. It would have been shocking if the uncertainty relation had been broken as then the piece of mathematics (or the Dirac quantization condition) would have been wrong, and so much of our understanding of quantum mechanics rests on the Dirac quantization condition.
8:50 reminds me a bit of how a balanced XLR audio cable works.
I had the same thought.
Only if you do it completely sideways. There’s so much different and yet could be viewed in the same methods. Just so different. Indeed
I had the same thought, plus twisted-pair telephone and ethernet cables.
I love PBS Spacetime. I love PBS Spacetime.
Summary:
∆N.∆phi > h/4π ------- Number phase relationship. N describe number(fock) states which have ∆N fixed and almost zero but this uncertainty is increased manually giving out squeezed states.

This isn't breaking the HUP. It's just using it in the intended way.
My thoughts exactly. More clickbait.
Yeah, the rule it's breaking is not the uncertainty principle at all. It's an obscure relationship that normally applies to laser light, and which only specialists have ever worked with or even heard of.
Trading off one uncertainty for another is routine in photography, e.g. when you change aperture sizes.
@@bryanreed742 Similar tradeoffs happen in music too. An in pretty much any application that involves both timing and frequency.
@@KohuGalyAt least for everything with frequency vs. time, it is given purely by the mathematics. However, we can also 'break' that uncertainty with additional preknown constraints of our system in some cases, like registering the general signature of something in the spectrum and then detecting fast changes of it in a lower resolution spectrum...
Just watched this - there were 1300 comments, I scrolled through and maybe 1/10 of them were about the clickbait title. Chances that they'll stop doing this? Probably less than 1/10 :(
This just makes me think of that DS9 episode with the group of genetically enhanced humans;
when O'Brien told Bashir, he can't break the fundamental laws of physics, they solve the issue and respond in unison: "But you can bend them!"
You could clip the wings off of an angel, dancing on the head of a pin.
A brilliant Way solutions to get around these issues. Amazing
5:40
When laser beams "destructively interfere", what happens to the energy they carry? Or maybe I should say: what happens to their photons? They don't just disappear, do they?
The photons simply don’t have any probability of being detected near that point. You are making it sound like there was a photon near that point and then it was inexplicably destroyed by the interference process. But instead, the truth is that when photons interfere with each other, the number of photons is still the same; the probabilities of finding the photons in particular regions of space simply change.
Since the photon is it's own anti particle they in fact do disappear. No photons means, no energy transfered/interaction, no problem. Thta's the baseline.
Since you asked where the energy in this experimetn goes. An interferometer, in fact, produces two beams as output, one destructive interfering and one constructive interfering (the second one is being discarded), so the neregy you detect is split off, from the second beam.
@@cahdoge Is that always the case? What if we didn't use an interferometer, but instead just sent two perfectly synchronized laser beams that would cancel each other out?
@@Trias805 There's a difference between the energy and its effect. The first involves the energy in the electromagnetic field at a point and the second invovles the net magnitude of the field.
With constructive interference this is a simple relationship, two photons add to give double the magnitude and thus double the effect. With destructive interference the energy is still there, but inacessible.
If there's enough you can get pair production, the opposite of matter-antimatter annihilation, but otherwise the EM waves are still there. Most likely the energy will travel until it reaches the source of its counterpart at which point it won't be cancelled out anymore and can interact.
I love being an engineer and giving physicists new toys 😂
Literally my reaction :D
Wonderfully clear and simple explanation. thank you.
So fresh! Love your work guys, thank you!
10:32 I think it should have said: "we were *unable* to film his position while shooting comments."
Just me?
If a "signal" came into LIGO at a perfect 45 degree angle between the two laser paths, could the stretching of spacetime be equal on both sides, thereby causing no disturbance?
that might be one of the reasons why there are two sites
Yes. That's a reason why there are two detectors in the US and another one in Europe.
There are two sites to make sure that what is detected at one is also detected at the other, and thus it is real signal (and not some kind of localized earthquake, trucks driving on roads, etc.) Having even more sites, that helps a lot with the sensitivity of all orientations. Also, you can use the difference in the time of the signal to help figure out the orientation (if the waves hit the European detector first, then the source is somewhere in that half of the sky).
I really enjoyed observing Matt's velocity, thanks!
Thank you for this well worded explanation.
There is no uncertainty when comes to clicking in newest Space Time episode. I'm pretty sure time of this interaction is not quantized and approximates to 1/∞
Bruh, just collapse and get on with it.
It just struck me that the pairs of variables most often used for the Uncertainty Principle (x vs p, or E vs t) are "Noether pairs". Conservation of momentum (from what I remember) comes from the symmetry of translations in position, and conservation of energy comes from symmetry of translations in time. Surely this isn't a coincidence, right?
they might have done a video about that: czcams.com/video/04ERSb06dOg/video.html

Very interesting, informative and worthwhile video.
So, how is this breaking the uncertainty principle? Unless I’m missing something, it still holds: you can decrease uncertainty about phase to an insane degree, but at the cost of increasing uncertainty about amplitude. That is exactly what the uncertainty principle says, isn’t it?
It is super impressive that scientists can measure things with such precision that Heisenbergs uncertainty principle even becomes relevant, but to suggest that they break that fundamental principle just seems wrong to me. Again, unless I'm missing something.
You are correct, it is a bad title for a cool subject.
You're not missing anything
4:40 Is the interpretation of the weak interaction as a W boson borrowing a huge amount of energy from the vacuum and existing for only a very short time an example of a natural instance of one variable being very certain and the other very uncertain?
Yes, though it's more like an interpretation of a natural phenomena through the lens of uncertainty. Other interpretations don't rely on that principle.

First half of video: OK I'm keeping up, I must be smarter than I thought!
Second half of video: Derpy derpy, space stuff and things....ha smart man said "Space Time".
That was interesting and informative. Thank you.
I realized that I found this episode somewhat more intuitive/easier to understand than the average upload. This is in part because it deals with concepts already familiar to me as a musician who regularly works with sound editing software. I would love to see some episodes explaining some of these concepts through the lens of sound, going into finer detail about waves, frequencies, vibrations, distortions, etc.
Professor Moriarty has made a few videos like that where he talked quantum physics while playing one of his guitars. I highly recommend seeking them out!
Doesn't seem broken to me.
This is wrong. The Heisenberg uncertinity limit is still preserved, there is no overcoming of such limit even with squeezed states used !
It is a wierd mistake from this very good channel.
He said it was more of a hack than actually breaking the limit! I think is was just a colorful play on words!
@@Create-The-Imaginable still, the title is misleading, rathar than just colorful different one.
@@ismailbarakat3868 I still think it is Marketing 101! But on a Scientific note... How can you "break" something that is uncertain? 😉 Marketing is sometimes good kind of like calling the Higgs Boson the "God Particle". lol
I understand about 2% of these videos; but I still watch every one.
Great video, please keep em comin!
Am I missing something, or is the title misleading and click-baity, and should more rightly be called "Using the uncertainty principle to push measurement accuracy to the limit"? There's no breaking of the uncertainty principle (as there shouldn't be), only tuning the uncertainty in the individual factors that make up the product? Totally within both the equation and even the layman understanding of it. Light squeezing is still really cool, but it's hugely important that science communication isn't misleading, even if it helps grab people's attention or makes the story seem more exciting.
I might be pedantic, but this ISN'T breaking Heisenberg's principle at all!
Correct. It is a clickbait video title.
brilliant. thank you
I've been watching your videos for years im pretty sure I've watched every single video on your CZcams channel
I don't appreciate clickbait titles. No law is actually broken or bent with squeezed light.
that's right. i'm used to pseudo-science channels doing this sort of thing but i think it is bad form to do it on a supposedly science channel.
Probably could be done by an observer of a different class, though
@@frun what does that mean? if you are rich you get a different perspective?
Wrong title in this video.
Nice touch on the squeeze sound effect!
Intriguing. Thank you.
