Hardy's Test versus the CHSH Test of Quantum Non-Locality: Fundamental and Practical Aspects
Daniel Braun, Mahn-Soo Choi
We compare two different tests of quantum non-locality, both in theoretical terms and with respect to a possible implementation in a mesoscopic circuit: Hardy's test [Hardy, Phys.…

Quantum Key Distribution Using Quantum Faraday Rotators
Taeseung Choi, Mahn-Soo Choi
We propose a new quantum key distribution (QKD) protocol based on the fully quantum mechanical states of the Faraday rotators. The protocol is unconditionally secure against collec…

Quantum Phase Transitions and Particle-Hole Pair Transport in Capacitively Coupled Josephson-Junction Chains
Mahn-Soo Choi, M. Y. Choi, Sung-Ik Lee
We consider two chains of ultrasmall Josephson junctions, coupled capacitively with each other, and investigate the transport of particle-hole pairs and the quantum phase transitio…
