ScholarBank@NUS Repository. https://doi.org/10.1088/1367-2630/17/9/093034 | Abstract: | We characterize correlations in polarization and time of photon pairs generated from a cold cloud of 87Rb 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 intermediate hyperfine levels. When allowing both decay paths, we observe quantum beats in time-resolved correlation measurements. © 2015 IOP Publishing Ltd and Deutsche Physikalische Gesellschaft. | Source Title: | New Journal of Physics | URI: | https://scholarbank.nus.edu.sg/handle/10635/175281 | ISSN: | 1367-2630 | DOI: | 10.1088/1367-2630/17/9/093034 |
