# Hong-Ou-Mandel interferometry on a biphoton beat note

@article{Chen2019HongOuMandelIO, title={Hong-Ou-Mandel interferometry on a biphoton beat note}, author={Yuanyuan Chen and Matthias Fink and Fabian Steinlechner and Juan P. Torres and Rupert Ursin}, journal={npj Quantum Information}, year={2019}, volume={5}, pages={1-6} }

Hong-Ou-Mandel interference, the fact that identical photons that arrive simultaneously on different input ports of a beam splitter bunch into a common output port, can be used to measure optical delays between different paths. It is generally assumed that great precision in the measurement requires that photons contain many frequencies, i.e., a large bandwidth. Here we challenge this “well-known” assumption and show that the use of two well-separated frequencies embedded in a quantum entangled…
