Generation of a non-zero discord bipartite state with classical second-order interference

2017 · Optics Express

We report an investigation on quantum discord in classical second-order interference. In particular, we theoretically show that a bipartite state with D = 0.311 of discord can be generated via classical second-order interference. We also …

Entanglement swapping via lossy channels using photon-number-encoded states

2024 · arXiv (Cornell University)

Entanglement shared between distant parties is a key resource in quantum networks. However, photon losses in quantum channels significantly reduce the success probability of entanglement sharing, which scales quadratically with the channel transmission. Quantum repeaters …
