“Time evolution generically entangles a quantum state with environmental degrees of freedom. The resulting increase in entropy changes the properties of that quantum system leading to “aging”. It is interesting to ask if this familiar property also applies to simple, single particle quantum systems such as the decay of a radioactive particle. We propose a test of such aging in an ion clock setup where we probe for temporal changes to the energies of the electronic state of an ion containing a radioactive nucleus. Such effects are absent in standard quantum mechanics and this test is thus a potent null test for violations of quantum mechanics. As a proof of principle, we show that these effects exist in causal non-linear modifications of quantum mechanics.” See full paper on the arXiv.

“Ralph, like us, was willing to be a fool. And the way to get to the top of the heap in terms of developing original research is to be a fool, because only fools keep trying. You have idea number 1, you get excited, and it flop. Then you have idea number 2, you get excited, and it flops. Then you have idea number 99, you get excited, and it flops. Only a fool would be excited by the 100th idea, but it might take 100 ideas before one really pays off. Unless you’re foolish enough to be continually excited, you won’t have the motivation, you won’t have the energy to carry it through. God rewards fools”

Stanford Computational Imaging Lab demonstrated an amazing non-line-of-sight imaging technique to detect moving objects. For more information see YouTube and IEEE.

“In the theory of quantum communications, a deeper structure has been recently unveiled – mainly within the physics community – showing that the capacity does not completely characterize the channel ability to transmit information due to phenomena with no counterpart in the classical world. Although how deep goes this structure is yet to be fully uncovered, it is crucial for the communication engineering community to own the implications of these phenomena for understanding and deriving the fundamental limits of communications. Hence, the aim of this paper is to shed light on these phenomena by providing the reader with an easy access and guide towards the relevant literature and the prominent results, by adopting a communication engineering perspective.”

We could have expected this to emerge from Vienna: Quantum + Music!

UK Space Agency and industry invested £235m into Quantum as a next-generation product. And, it’s named Quantum for a reason: quantum communications is the next-generation technology!

Gerard Hooft’s opinion on the interpretation of quantum mechanics. “Not only may quantum mechanics be a description of the sub-microscopic world that is profoundly different from what is often asserted, particularly concerning ‘what is really going on’, but questions such as these may well be essential for finding new ways of constructing models beyond what is now called the Standard Model of the sub-atomic particles.” See arXiv:2104.03179.
