Receiver Operating Characteristics for a Prototype Quantum Two-Mode Squeezing Radar [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2019
We built and evaluated a prototype quantum radar, which we call a quantum two-mode squeezing (QTMS) radar, in the laboratory. It operates solely at microwave frequencies; there is no downconversion from optical frequencies.
