Robust Generation of Topological Biphoton Mode via Adiabatic Passage
Jaesung Lim, Jihwan Kim, Dong-Gil Im +4
Topological waveguide arrays support robust mode propagation in the presence of fabrication imperfections, providing a significant advantage for on-chip quantum information process…
Quantum Radar Cross Section with two-photon entangled states
Sunghwa Kang, Jihwan Kim, Zaeill Kim +7
We study two-photon entangled states for quantum radar cross section (QRCS), which is an extension of a single-photon QRCS formula. Since signal-idler entanglement does not provide…
Quantum target ranging with Hetero-Homodyne detection
Sangwoo Jeon, Yonggi Jo, Jihwan Kim +4
Quantum target ranging, which estimates a target position using entangled photon pairs, is known to offer an error-probability advantage over classical ranging strategies. Yet, rea…
Single-shot detection limits of quantum illumination with multi-qudit states
Sunghwa Kang, Yonggi Jo, Jihwan Kim +3
Quantum illumination is a protocol for detecting a low-reflectivity target by using two-mode entangled states composed of signal and idler modes, which can outperform unentangled s…
Microwave Quantum Illumination with Optical Memory and Single-Mode Phase-Conjugate Receiver
Sangwoo Jeon, Jihwan Kim, Duk Y. Kim +3
Microwave quantum illumination with entangled pairs of microwave signal and optical idler modes, can achieve the sub-optimal performance with joint measurement of the signal and id…
