Quantum mechanical complementarity probed in a closed-loop Aharonov-Bohm interferometer
Dong-In Chang, Gyong Luck Khym, Kicheon Kang +6
According to Bohr's complementarity principle, a particle possesses wave-like properties only when the different paths the particle may take are indistinguishable. In a canonical e…
Beating of Aharonov-Bohm oscillations in a closed-loop interferometer
Sanghyun Jo, Gyong Luck Khym, Dong-In Chang +5
One of the points at issue with closed-loop-type interferometers is beating in the Aharonov-Bohm (AB) oscillations. Recent observations suggest the possibility that the beating res…
Conditional relaxation of a charge state under continuous weak measurement
Gyong Luck Khym, Kicheon Kang
We investigate the conditional evolution of a charge state coupled to a mesoscopic detector under continuous weak measurement. The state suffers relaxation into a particular state…
Nonlocality of Dephasing in a Charge Qubit Interacting with a Quantum Point Contact Beam Collider
Youngnae Lee, Gyong Luck Khym, Kicheon Kang
We investigate the charge-detection-induced dephasing of a charge qubit interacting with an electronic beam collider composed of a quantum point contact. We report that, while the…
Charge State Measurement and Persistent Current in a Double-Dot Aharonov Bohm Ring
