Linear-optical implementations of the iSWAP and controlled NOT gates based on conventional detectors
Linear-optical implementations of the iSWAP and controlled NOT gates based on conventional detectors
The majority of linear-optical nondestructive implementations of universal quantum gates are based on single-photon resolving detectors. We propose two implementations, which are nondestructive (i.e., destroying only ancilla states) and work with conventional detectors (i.e., which do not resolve number of photons). Moreover, we analyze a recently proposed scheme of Wang …
