India, April 7 -- The Government of India has issued a release:

A recent study by an international team of researchers reveals a fundamental limitation of classical communication: no finite amount of classical messaging can faithfully simulate a quantum communication channel. This result not only deepens our understanding of the foundations of physics but also carries significant implications for the development of future quantum technologies.

Can quantum processes be faithfully reproduced using only classical resources? This deceptively simple question, first asked by Richard P. Feynman in a seminal paper marks the boundary between classical and quantum descriptions of nature and lies at the heart of what we mean by quantum advantage in ...
