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…
Quantum illumination receiver using double homodyne detection
Yonggi Jo, Sangkyung Lee, Yong Sup Ihn +2
A quantum receiver is an essential element of quantum illumination (QI) which outperforms its classical counterpart, called classical-illumination (CI). However, there are only few…
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 entangled coherent states in lossy quantum-enhanced metrology
Su-Yong Lee, Yong Sup Ihn, Zaeill Kim
We investigate an optimal distance of two components in an entangled coherent state for quantum phase estimation in lossy interferometry. The optimal distance is obtained by an eco…
