Quantum Provides Truly Secure Communication

Still the case? 

Quantum Encryption Could Support Truly Secure Communication

Silicon Republic, Leigh McGowran, July 27, 2022

A new form of quantum cryptography could eventually support truly secure communication by facilitating quantum key distribution between two devices based on quantum entanglement, according to an international team of scientists. Researchers confined two single ions—a sender and a receiver—in separate traps connected by optical fiber. Entanglement allows the sender and receiver to generate shared outcomes without third-party interference. Researchers said this system could lead to two-party communication that is "fundamentally beyond" an adversary's control and also could ensure private communication with just a few general assumptions about the devices used .....
