Paper Abstract

We present a method, known as hyperdense coding, which uses photons hyperentangled in polarization and temporal mode to transmit up to 2.81 bits/photon of classical information over a two-qubit quantum channel. Furthermore, the hyperentangled photons used in this approach are much less susceptible to the influences of turbulence than spatial qubits, allowing for turbulence-resistant communication. We compare this technique to previously implemented hyperentanglement-enhanced superdense coding implementations which have a maximum theoretical channel capacity of 2 bits/photon.
