Entanglement and Berry Phase in Two Interacting Qubits
Ai Min Chen, Sam Young Cho, Taeseung Choi
Entanglement and Berry phase are investigated in two interacting qubit systems. The XXZ spin interaction model with a slowly rotating magnetic field is employed for the interaction…
Entanglement of thermal scalar fields in a compact space space
Jae-Weon Lee, Jaewan Kim, Taeseung Choi
Using the thermal Green's function approach we propose a general method to investigate entanglement of the vacuum state or thermal ground states in an arbitrary dimensional space-t…
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 Separability of the vacuum for Scalar Fields with a Boundary
Jae-Weon Lee, Jaewan Kim, Taeseung Choi
Using the Green's function approach we investigate separability of the vacuum state of a massless scalar field with a single Dirichlet boundary. Separability is demonstrated using…
