Abstract
Systems and methods for a quantum computing include a plurality of photonic processing stages, a plurality of heralding-free connections, and circuitry configured to regulate photon flow between adjacent stages such that decisions about stage settings or flow between adjacent stages are free of input from a previous stage. Each heralding-free connection is located between adjacent photonic processing stages. Each photonic processing stage includes at least two of an optical switch, a beam splitter, a waveguide or a photon generator. Methods include transmitting or receiving a plurality of photons via a plurality of heralding-free connections, and regulating photon flow between adjacent stages such that decisions about stage settings or flow between adjacent stages are free of input from a previous stage.
