Quantum resonance based encryption protocol with quantum kicked top
arXiv:2606.01953
Abstract
We propose a genuine quantum protocol for protecting user's data, either in a shared quantum computer or in a quantum communication system, that is not accessible even to the service provider. The protocol is based on quantum kicked top -- the dynamics of a spin system -- operating in the regime of quantum resonance. This protocol ensures perfect recovery for authorized users while making intercepted states appear mixed to eavesdroppers, with built-in tampering detection. This protocol can be used for secure communication between two parties in geographically different locations, and also for quantum key distribution. The effectiveness of this protocol is demonstrated by assuming a quantum computer with quantum memory and functioning quantum networks. In the absence of the latter, at present, the protocol can be demonstrated in a laboratory using currently available quantum computing platforms.
