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.…
User-independent optical path length compensation scheme with sub-ns timing resolution for 1xN quantum key distribution network system
Byung Kwon Park, Min Ki Woo, Yong-Su Kim +3
Quantum key distribution (QKD) networks constitute promising solutions for secure communication. Beyond conventional point-to-point QKD, we developed 1xN QKD network systems with a…
Nonlocal quantum correlations under amplitude damping decoherence
Tanumoy Pramanik, Young-Wook Cho, Sang-Wook Han +3
Different nonlocal quantum correlations of entanglement, steering and Bell nonlocality are defined with the help of local hidden state (LHS) and local hidden variable (LHV) models.…
Experimental comparison of various quantum key distribution protocols under reference frame rotation and fuctuation
Juhwan Yoon, Tanumoy Pramanik, Byung Kwon Park +4
In free-space quantum key distribution (QKD) between moving parties, e.g., free-space QKD via satellite, the reference frame rotation and fluctuation degrades the performance of QK…
