Method for generating squeezed quantum illumination light source and quantum radar device using the same

A quantum radar device using a squeezed quantum illumination light source, the device comprising:

• a transmitter configured to transmit a radar signal;
• a receiver configured to receive a radar signal;
• and
• a controller configured to control the transmitter and the receiver,
• wherein the controller is configured to:
• generate a dual mode squeezed light source that includes a signal mode and an idler mode;
• determine 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;
• determine 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
• squeeze the dual mode squeezed light source based on the squeezing angle and the degree of operation.

A computer-readable non-transitory medium having a program for generating a squeezed quantum illumination light source, the program comprising instructions for:

• generating a dual mode squeezed light source including a signal mode and an idler mode;
• determining 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.
