Quantum illumination with non-Gaussian states: Bounds on the minimum error probability using quantum Fisher information
Changsuk Noh, Changhyoup Lee, Su-Yong Lee
Quantum illumination employs entangled states to detect a weakly reflective target in a thermal bath. The performance of a given entangled state is evaluated from the minimum error…
Quantum illumination with asymmetrically squeezed two-mode light
Yonggi Jo, Taek Jeong, Junghyun Kim +4
We propose Gaussian quantum illumination(QI) protocol exploiting asymmetrically squeezed two-mode(ASTM) state that is generated by applying single-mode squeezing operations on each…
Surviving Entanglement in Optic-Microwave Conversion by Electro-Optomechanical System
Yonggi Jo, Su-Yong Lee, Yong Sup Ihn +3
In recent development of quantum technologies, a frequency conversion of quantum signals has been studied widely. We investigate the optic-microwave entanglement that is generated…
Coherent multi-mode conversion from microwave to optical wave via a magnon-cavity hybrid system
Yong Sup Ihn, Su-Yong Lee, Dongkyu Kim +2
Coherent conversion from microwave to optical wave opens new research avenues towards long distant quantum network covering quantum communication, computing, and sensing out of the…
Quantum illumination via quantum-enhanced sensing
Su-Yong Lee, Yong Sup Ihn, Zaeill Kim
Quantum-enhanced sensing has a goal of enhancing a parameter sensitivity with input quantum states, while quantum illumination has a goal of enhancing a target detection capability…
Optimal quantum phase estimation with generalized multi-component Schrodinger cat states
Seung-Woo Lee, Su-Yong Lee, Jaewan Kim
In this paper, we are interested in detecting the presence of a nearby phase-sensitive object, where traveling light works out under a low-photon loss rate. Here we investigate the…
