Abstract
An optical receiver includes a squeezer for changing the quantum state of a signal lightwave to a squeezed state, a slave laser put in an injection locking state by the signal lightwave outputted from the squeezer, and an optical homodyne detector for carrying out optical homodyne detection for the signal lightwave outputted from the slave laser.
