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 Dissipative Dynamics of Entanglement in the Spin-Boson Model
Jong Soo Lim, Mahn-Soo Choi, M. Y. Choi
We study quantum dissipative dynamics of entanglement in the spin-boson model, described by the generalized master equation. We consider the two opposite limits of pure-dephasing a…
Andreev Bound States in the Kondo Quantum Dots Coupled to Superconducting Leads
Jong Soo Lim, Mahn-Soo Choi
We have studied the Kondo quantum dot coupled to two superconducting leads and investigated the subgap Andreev states using the NRG method. Contrary to the recent NCA results [Cler…
Pair Tunneling and shot noise through a single molecule in a strong electron-phonon coupling
Myung-Joong Hwang, Mahn-Soo Choi, Rosa Lopez
We investigate the electronic transport through a single molecule in a strong electron-phonon coupling regime. Based on a particle-hole transformation which is made suitable for no…
Quantum-based Mechanical Force Realization in Pico-Newton Range
Jae-Hyuk Choi, Min-Seok Kim, Yon-Kyu Park +1
We propose mechanical force realization based on flux quantization in the pico-Newton range. By controlling the number of flux quantum in a superconducting annulus, a force can be…
Magnetoresistance of a quantum dot with spin-active interfaces
Audrey Cottet, Mahn-Soo Choi
We study the zero-bias magnetoresistance MR of an interacting quantum dot connected to two ferromagnetic leads and capacitively coupled to a gate voltage source Vg. We investigate…
