Phonon-mediated population inversion in a semiconductor quantum-dot cavity system
S. Hughes, H. J. Carmichael
We investigate pump-induced exciton inversion in a quantum-dot cavity system with continuous wave drive. Using a polaron-based master equation, we demonstrate excited-state populat…
Onset of a Quantum Phase Transition with a Trapped Ion Quantum Simulator
R. Islam, E. E. Edwards, K. Kim +8
A quantum simulator is a well controlled quantum system that can simulate the behavior of another quantum system which may require exponentially large classical computing resources…
Entangled-state cycles from conditional quantum evolution
M. Gu, S. Parkins, H. J. Carmichael
A system of cascaded qubits interacting via the oneway exchange of photons is studied. While for general operating conditions the system evolves to a superposition of Bell states (…
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…
