Distinguishing two single-mode Gaussian states by homodyne detection: An information-theoretic approach
Hyunchul Nha, H. J. Carmichael
It is known that the quantum fidelity, as a measure of the closeness of two quantum states, is operationally equivalent to the minimal overlap of the probability distributions of t…

Entanglement within the Quantum Trajectory Description of Open Quantum Systems
Hyunchul Nha, H. J. Carmichael
The degree of entanglement in an open quantum system varies according to how information in the environment is read. A measure of this contextual entanglement is introduced based o…

Proposed Test of Quantum Nonlocality for Continuous Variables
Hyunchul Nha, H. J. Carmichael
We propose a test of nonlocality for continuous variables using a two-mode squeezed state as the source of nonlocal correlations and a measurement scheme based on conditional homod…
