1. A method of generating a squeezed quantum illumination light source, the method comprising:
generating a dual mode squeezed light source comprising a signal mode and an idler mode;
obtaining a degree of additional squeezing for the dual mode squeezed light source based on object information and information about the receiver configured to receive the dual mode squeezed light source;
determining a squeezing angle and a degree of operation that satisfy the degree of additional squeezing for each of the signal mode and the idler mode; and
squeezing the dual mode squeezed light source based on the squeezing angle and the degree of operation.
