Using AI to accurately quantify the amount of entanglement in a system
An international team of physicists has found that deep-learning AI technology can accurately quantify the amount of entanglement in a given system—prior research has shown that the degree of "quantumness" of a given system ...
Exploiting nonlinear scattering medium for optical encryption, computation and machine learning
Can one see through a scattering medium like ground glass? Conventionally, such a feat would be deemed impossible. As light travels through an opaque medium, the information contained in the light becomes "jumbled up," almost ...
