Abstract
Circuits and methods can implement reconfigurable spatial rearrangement (also referred to as 'spatial multiplexing') for a group of photons propagating in waveguides. For instance, two sets of small optical multiplexer circuits (such as two sets of 2×2 optical multiplexer circuits or two sets of 3×3 optical multiplexer circuits) can be used to rearrange a pattern of photons on a first set of waveguides into a usable input pattern for a downstream optical circuit.
