Multi-objective design of photon blockade for bright single-photon sources
Sunkyu Yu, Xianji Piao, Namkyoo Park
High-quality single-photon sources, realized through saturable emitters, photon blockade, or heralded pair generation, are indispensable building blocks for photonic quantum platfo…

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…
