Performance of hybrid entanglement photon pair source for quantum key distribution
Performance of hybrid entanglement photon pair source for quantum key distribution
We report on the experimental demonstration of a source of hybrid entanglement pairs between two different degrees of freedom, a 1550 nm time-bin qubit and an 810 nm polarization qubit. The polarization qubit at 810 nm is transformed by an asymmetric Mach–Zehnder interferometer consisted of a Glan laser prism and …
