Entanglement swapping via lossy channels using photon-number-encoded states
Wan Zo, Bohdan Bilash, Donghwa Lee +5
Entanglement shared between distant parties is a key resource in quantum networks. However, photon losses in quantum channels significantly reduce the success probability of entang…
Characterizing Bell state analyzer using weak coherent pulses
Donghwa Lee, Young-Wook Cho, Hyang-Tag Lim Sang-Wook Han +3
Bell state analyzer (BSA) is one of the most crucial apparatus in photonic quantum information processing. While linear optics provide a practical way to implement BSA, it provides…
Equitable multiparty quantum communication without a trusted third party
Tanumoy Pramanik, Dong-Hwa Lee, Young-Wook Cho +6
Multiparty quantum communication provides delightful applications including quantum cryptographic communication and quantum secret sharing. Measurement-Device-Independent (MDI) qua…
Reference-Frame-Independent, Measurement-Device-Independent quantum key distribution using fewer quantum states
Donghwa Lee, Seong-Jin Hong, Young-Wook Cho +6
Reference-Frame-Independent Quantum Key Distribution (RFI-QKD) provides a practical way to generate secret keys between two remote parties without sharing common reference frames.…
