1. Apparatus comprising:
a squeezer configured to transform input coherent-state light to input squeezed-state light;
a passive waveguide splitter configured to receive the input squeezed-state light, and configured to output first squeezed-state light and second squeezed-state light;
a phase shifter configured to impose a relative phase shift between the first squeezed-state light and the second squeezed-state light according to an input of the phase shifter;
a passive waveguide combiner configured to receive the first squeezed-state light and the second squeezed-state light from the phase shifter, and configured to provide output squeezed-state light;
an anti-squeezer configured to receive the output squeezed-state light and configured to provide output coherent-state light.
