Abstract

We propose a two-step quantum key distribution protocol using frequency and polarization hyperentangled photons. In this protocol, key information is encoded by unitary operations on the hyperentangled photons, and the hyperentangled photons are sent in two steps. We also designed a state measurement device and analyzed the security of the protocol.
