Abstract :

Entanglement, the quintessential quantum correlations between two quantum systems, has been widely used in quantum communication over the past decades. The distribution of entanglement is a crucial module in many quantum information processing protocols. However, in a practical transmission, entanglement is easily influenced by the noise in quantum channel, which will turn the maximally entangled state into a mixed state. To overcome the influence from channel noise, we present a self-error-correction hyperentanglement distribution scheme for three-photon system in both spatial and polarization degrees of freedom with linear optical elements and Pockel cells. In our scheme, the three-photon system is initially prepared in a spatial-polarization hyperentangled state and subsequently encoded into time-bin entangled state which is rather robust and hard to be affected by the channel noise. After transmitting over the noisy channels, the time-bin entanglement is transformed into spatial-polarization hyperentanglement. Thus, with our scheme, the parties in quantum communication can share maximally hyperentangled states in spatial and polarized degrees of freedom with the success probability of 100% in principle.
