1. A method for switching photons, the method comprising:
providing a network comprising a plurality of photon switches interconnected by a plurality of optical paths, each photon switch of the plurality of photon switches comprising a defect in a body of a semiconductor material and first and second distinct optical waveguides which respectively provide first and second output paths from the photon switch;
initializing the defect of each photon switch of the plurality of photon switches to a respective first computational state, the respective first computational state for the defect of each photon switch of the plurality of photon switches being selected from:
a first basis state in which the defect is optically coupled to one or more photon modes in the first optical waveguide of the photon switch;
a second basis state in which the defect is not optically coupled to the one or more photon modes in the first optical waveguide of the photon switch; and
a superposition of the first and second basis states;
delivering a first photon to a first one of the plurality of photon switches by a first one of the plurality of optical paths; and
based on the first computational state of the defect of the first one of the plurality of photon switches, selectively coupling the first photon to a second one of the plurality of photon switches by the first output path of the first one of the plurality of photon switches or to a third one of the plurality of photon switches by the second output path of the first one of the plurality of photon switches.
