Quantum state discrimination plays a pivotal role in quantum information science, underpinning tasks such as quantum communication, cryptography and computing. Fundamental to this endeavour is the ...
Quantum state distinguishability in nonlocal systems addresses the fundamental question of how well observers, each holding a part of a composite quantum system, can identify an unknown quantum state ...
A team of physicists in Japan has figured out how to identify a fragile, three-photon quantum state in a single measurement, ...
The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...
