Abstract
Provided is a quantum encryption communication apparatus of a transmission side which performs a communication process based on quantum encryption, including: a light source unit which generates a light pulse; a polarization modulating unit which performs polarization modulation of the light pulse by using a variable wavelength plate; and a controller which drives the variable wavelength plate to convert a polarization state of the light pulse to one of a plurality of predetermined polarization bases at random.
