A new paper titled "Indistinguishability Obfuscation from Well-Founded Assumptions" may have unlocked a decades-old encryption puzzle. Is it possible to encrypt a computer program such that the code ...

In a world of quantum oddities, the phenomenon of indistinguishability, the impossibility of distinguishing between two quantum particles, remains notable. Superposition is one of the underlying ...

Who’s who: The quantum Alice in Wonderland would like to understand whether the many “Twindeldum-Twindeldees” she sees are really identical or not, and uses the new interferometer for this purpose.

In 2018, Aayush Jain, a graduate student at the University of California, Los Angeles, traveled to Japan to give a talk about a powerful cryptographic tool he and his colleagues were developing. As he ...

Theoretical physicists at the University of Palermo (Italy) have recently developed a study showing how controllable spatial indistinguishability of identical subsystems can be an inherent control of ...

In this work, we discuss a formal way of dealing with the properties of contextual systems. Our approach is to assume that properties describing the same physical quantity, but belonging to different ...
