What we've done is produce room-temperature, microscopic LED-like devices that emit correlated photon pairs. What are some of the challenges you faced? Two-photon emission is a relatively weak ...

Through spontaneous parametric down-conversion (SPDC), it can generate correlated photon pairs for quantum key distribution, teleportation, and computing. For SPDC to be efficient, phase matching ...

Even after that photon is gone, we have a correlation between two distant or 'nonlocal,' qubits. Remote entanglement allows us to take advantage of these correlations and perform parallel ...
