Qubit entanglement between ring-resonator photon-pair sources on a silicon chip
Qubit entanglement between ring-resonator photon-pair sources on a silicon chip
Entanglement--one of the most delicate phenomena in nature--is an essential resource for quantum information applications. Large entangled cluster states have been predicted to enable universal quantum computation, with the required single- qubit measurements readily implemented with photons. Useful large-scale systems must generate and control qubit entanglement on-chip, where quantum information …
