A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to new heights.

Recently, researchers from the University of Science and Technology of China (USTC) reveals that not all forms of quantum nonlocality guarantee intrinsic randomness. They demonstrated that violating ...

A research team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), led by Prof. PAN Jianwei, ZHANG Qiang, and CHEN Kai, in collaboration with CHEN ...

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 ...

Classical and quantum mechanics don’t really get along as the science of the subatomic can get, well, weird. Take, for instance, quantum entanglement, which says that the state of one particle can be ...
