Securing Global Communications: Introducing QUBE
Quantum Key Distribution (QKD) allows two parties to securely communicate with each other without allowing anyone to eavesdrop.
Our cube satellite QUBE is a small research satellite testing technology towards global QKD. In this video, we introduce the satellite as well as the quantum payload from LMU and MCQST.
About QUBE
For the first time, the research satellite QUBE will test newly developed quantum communication technologies using a very small satellite in space. The objective is to support secure, worldwide data transmission in the future.
QUBE is a joint project with OHB GmbH, DLR, LMU Munich and the Max Planck Institute for the Physics of Light. In this collaboration, advanced quantum technologies are combined with powerful optical communication systems and integrated into an innovative CubeSat system.
The video was created by Lukas Knips, researcher in the group of Harald Weinfurter, who has led the QUBE consortium.

    What is not understood today is that there are three distinct dimensions: Consciousness; Mind; Elemental. We are in a Material or Atomic Age and the elemental only or matter is seen as real and fundamental. Consciousness and Mind are seen as derivative and that makes Consciousness ‘the hard problem’ for philosophy. Also there are likely more electricities than the two that have been discovered; the environmental one; and the one in entities. As there are five elements and five senses there are likely five electricities. With the discovery of more electricities and more understanding of electromagnetism; the knowledge of which is due to Maxwell; there is also the mystery of magnetism itself. These further discoveries will change our lives and how we live. Philosophy now has become less cognitive and its adherents appears to think for it to matter it must leave thought experiments behind and instead concentrate on the elemental. That is a mistake, as so much that matters comes from thought experiments which can then be applied to the empirical to test them out. That is how science progresses. The non-tangible is not valued now, likely due to this being a material age, so what is empirical reigns. Philosophy is important to all disciplines as how we detach from the empirical and view it objectively is very important to not being immersed in the elemental. Like Merlin threatened with being banished into the earth we, and life, would lose the magic. Also the materialists are on a constant quest to own the narrative now with eliminative materialism and the idiocy of trans humanism or humans embedded with technology. Materialists are clueless about human consciousness; the human mind and their infinite potentials.

    You said the waveguide was a one-way transmission line, is that purely because there are emitters at one end and receivers at the other end? But if a photon is partially reflected back from the detector to the emitter would it perhaps interfere?

    If the Oxford philosopher P.F. Strawson is right that things sensed are mentally acquired one way (causally) in direct sensory interaction and become reformulated in developed reflection, in the first case (material content) what is seen is observer independent and world relative and in reflection are observer relative as observer related in the form of "objects", i.e., as individuated as "person concerning", then two realisms coexist in a mature experience: a personalized experience formed as common sense and scientific realism which leaves out the point of view (localized) of the person and the phenomena of subjective personal concern in order to only consider "thing space objects" of worldly particulars (abstracted from the duality of mind-body experience so as to explore worldly matter beyond the objects of concern of an observer. Dualism, and, thus, skepticism, is avoided by recognizing that observable things are material and always the same no matter the form while formed things have no matter of their own. Experience is a learned and applied transformative activity of on-going individuating. Strawson, on such grounds as these claims common sense reality and scientific reality are purpose-given formalizations of experience expressing different perceived concerns of a vulnerable sentient being in a dangerous world of things (particulars) subject to the harsh economies of energy. In both cases, individuals care in different practical ways about contingent content-materiality. By stipulation, the world doesn't care a bit about being cared about. Refs for Strawson: "Perception and it s objects" the first three chapters of "Individuals," and "Bounds of Sense."

    basically there is more entanglement that can pass through the system. the photons build into a field and then the varying pulses of light are able to be translated into an energy field that can respond to the entanglement and then vibrate that energy down the given wire to the intended system.

  • @helicalactual
    @helicalactual Před 9 měsíci

    so, it's a translation problem.

  • @helicalactual
    @helicalactual Před 9 měsíci

    so when you generate an artificially entangled system, its very difficult to keep out the "noise" or interference. if the quantum computers are sensitive to other entities or entanglement structures, then other entanglement structures such as another quantum computer requiring thermo-dynamic stability that would generate a lot of waste heat and energy, manifesting a decoherence problem thusly thinning the entanglement for all computers. much like heat from CPU processors, but instead of heat, it's because entanglement is fragile and so thermodynamically expensive to maintain artificial entanglement. as a result, very difficult to get the systems to "speak to one another".

    I love these videos (Dialogues on the Foundations). It's fun to listen to during long summer evenings. As a side note, it's interesting to see people refer to Einstein's relativity theory as "classical". I thought classical gravity was Newton's. But I guess profs Liberati and Oriti are several levels above that so that they consider Einstein's theories "classical".

      usually when physicists say ''classical'' they refer to no quantum-theories, like Einstein's general relativity.
