Original Abstract Submitted
A quantum key delivery system in which a first transmission device phase modulates a first polarization component of two orthogonal polarization components in transmitted light and modulates a second polarization component, which is the other polarization component, into a signal indicating the second random number sequence, based on a first random number sequence indicating the bit sequence to be transmitted and the second random number sequence indicating the base in the phase modulation of the bit sequence to be transmitted; and a second transmission device separates orthogonal polarization modes in the received light and extracts a clock timing from the signal indicating the second random number sequence.
