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…
Single-Copy Certification of Two-Qubit Gates without Entanglement
Yujun Choi, Tanmay Singal, Young-Wook Cho +5
A quantum state transformation can be generally approximated by single- and two-qubit gates. This, however, does not hold with noisy intermediate-scale quantum technologies due to…
Observing the "quantum Cheshire cat" effect with noninvasive weak measurement
Yosep Kim, Dong-Gil Im, Yong-Su Kim +4
One of the common conceptions of nature, typically derived from the experiences with classical systems, is that attributes of the matter coexist with the substance. In the quantum…
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…
