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…
Time-spectral control of accidental coincidences in daylight entanglement-based free-space QKD
Jiyoung Moon, Yonggi Jo, Zaeill Kim +2
Daylight entanglement-based free-space quantum key distribution (QKD) is limited by accidental coincidences from receiver-admitted background light. We develop and experimentally v…
Recon?figurable measurement scheme compatible with MDI-QKD and BB84 protocols using single-laser sideband generation
Jaesung Lim, Yonggi Jo, Nam Hun Park +2
A quantum network can be operated efficiently by switching between measurement-device independent quantum key distribution (MDI-QKD) and BB84 according to the trust level of an int…
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…
