Quantum Key Distribution by Quantum Energy Teleportation
For quantum cryptography, this work proposes a new QKD paradigm using QET, but the analysis is theoretical and lacks concrete performance numbers.
The paper constructs a quantum key distribution protocol based on quantum energy teleportation and analyzes its security and noise robustness, extending it to an N-party information sharing protocol with dishonest participant detection.
Quantum energy teleportation (QET) is a process that leverages quantum entanglement and local operations to transfer energy between two spatially separated locations without physically transporting particles or energy carriers. We construct a QET-based quantum key distribution (QKD) protocol and analyze its security and robustness to noise in both the classical and the quantum channels. We generalize the construction to an $N$-party information sharing protocol, possessing a feature that dishonest participants can be detected.
