Abstract
The objective of the present invention is to provide a quantum receiver using square of homodyne detection for detecting a target of a quantum radar by using the square of homodyne detection that uses homodyne detection used in quantum information processing using continuous variables, and data processing, and a measurement method therefore. In order to achieve the above objective, the quantum receiver for detecting a target of a quantum radar using the square of homodyne detection according to the present invention comprises: a first 50:50 beam splitter for mixing signals coming into an input terminal; and two light quantity measurement units for measuring the quantity of light respectively outputted to two output terminals of the first 50:50 beam splitter.
