Polarization-entanglement-conserving frequency conversion of photons
Polarization-entanglement-conserving frequency conversion of photons
Entangled photons play a pivotal role in the distribution of quantum information in quantum networks. However, the frequency bands for optimal transmission and storage of photons are often not the same. Here, we experimentally demonstrate the coherent frequency conversion of photons entangled in their polarization, a widely used degree of …
