摘要： An apparatus for processing a photonic qubit signal includes a first optical unit to receive and transmit a time-modulated signal divided into two sections distinguished with respect to time and correspond to |0 and |1 states of single-photon qubit information; a second optical unit to form a first path-signal pattern by distributing the time-modulated signal into two spatial paths; a third optical unit to form a second path-signal pattern from the first path-signal pattern by inducing a relative delay and controlling a phase difference between signals on the two spatial paths; a fourth optical unit to form a third path-signal pattern through optical interference of the second path-signal pattern; and a fifth optical unit to control a phase difference between signals on the two spatial paths and form a fourth path-signal pattern through optical interference of the third path-signal pattern.
