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 ...

To really take off, advanced quantum information processing will require getting a better (experimental) grasp of an essential phenomenon called “indistinguishable photons.” A high degree of ...

When we observe the world at our scale, everything seems to obey predictable laws, those of classical physics. But when diving into the universe of particles, the rules change. Quantum phenomena often ...

PALO ALTO, Calif.--(BUSINESS WIRE)--NTT Research, Inc., a division of NTT (TYO:9432), along with UCLA and the University of Washington, today announced that a paper co-authored by cryptographers ...

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 ...
