Classical messaging cannot replicate quantum channels, study finds

A recent international study has established a fundamental limitation of classical communication, concluding that no finite amount of classical messaging can accurately simulate a quantum communication channel. The findings mark a significant advance in understanding the boundary between classical and quantum physics, with important implications for future quantum technologies. The research builds on a long-standing question first posed by Richard P. Feynman: whether quantum processes can be fa...
