Quantum encryption design overcomes Shannon's theorem to achieve perfect secrecy with reusable keys
Zixuan Hu, Zhenyu Li
Shannon's perfect-secrecy theorem states that a perfect encryption system that yields zero information to the adversary must be a one-time pad (OTP) with the keys randomly generate…
