Findings
The QET-based QKD protocol is secure under certain noise conditions.
The protocol can detect dishonest participants in multi-party sharing.
The approach offers a new method for secure quantum communication.
Abstract
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 -party information sharing protocol, possessing a feature that dishonest participants can be detected.
