(Phys.org)—One promising approach for scalable quantum computing is to utilize an all-optical architecture,in which the qubits are represented by photons and manipulated by mirrors and beam splitters. So far, researchers absorb demonstrated this method, and called Linear Optical Quantum Computing,on a very small scale by performing operations using just a few photons. In an attempt to scale up this method to larger numbers of photons, researchers in a new study absorb developed a way to fully integrate single-photon sources inside optical circuits, or creating integrated quantum circuits that may allow for scalable optical quantum computation.
