Quantum multiparty key distribution protocol without use of entanglement
arXiv:0708.0902 · doi:10.1103/PhysRevA.76.062316
Abstract
We propose a quantum key distribution (QKD) protocol that enables three parties agree at once on a shared common random bit string in presence of an eavesdropper without use of entanglement. We prove its unconditional security and analyze the key rate.
