Disentanglement due to polarization mode dispersion in optical fibers: from nonlocal compensation to entanglement sudden death
Misha Brodsky, Cristian Antonelli, Mark Shtaif · 2010
We propagate pairs of polarization-entangled photons through optical fibers with polarization-mode dispersion (PMD). We observe non-local PMD compensation and the transition to sudden death of entanglement when the alignment of the compensating element is varied.
