Polarization entanglement and quantum beats of photon pairs from four-wave mixing in a cold 87Rb ensemble
We characterize correlations in polarization and time of photon pairs generated from a cold cloud of ^87 Rb atoms via a four-wave mixing process in a cascade level scheme. Quantum state tomography reveals entangled polarization states of high purity for each of the decay paths through two different...
