Funds for Dr. Cristian Antonelli to visit ARL-Adelphi. Dr. Antonelli will meet with researchers to discuss photon entanglement degradation due to polarization effects in quantum networks
Abstract
Polarization mode dispersion (PMD) and polarization dependent loss (PDL) are critical issues in implementing long-distance fiber-based quantum networks. PMD and PDL result in a degradation of polarization entanglement that must be fully understood and accounted for when building a quantum network. We plan to theoretically and experimentally characterize how the amount of birefringence in the path of each photon of the entangled pair degrades the polarization entanglement of the two-photon state. Then we will examine entanglement degradation due to polarization effects as a function of the bandwidth of the pump used to generate the entangled photons and the bandwidths of the entangled photons themselves. Finally, the effects of stochastic PMD on polarization and frequency entanglement will be: analyzed both numerically and analytically.
