Coherence enhanced quantum metrology in a nonequilibrium optical molecule
Zhihai. Wang, Wei Wu. Guodong Cui, Jin. Wang
We explore the quantum metrology in an optical molecular system coupled to two environments with different temperatures, using a quantum master equation beyond secular approximatio…
Entanglement Evolution in the Presence of Decoherence
Jin Wang, Herman Batelaan, Jeremy Podany +1
The entanglement of two qubits, each defined as an effective two-level, spin 1/2 system, is investigated for the case that the qubits interact via a Heisenberg XY interaction and a…
Towards feedback control of entanglement
Stefano Mancini, Jin Wang
We provide a model to investigate feedback control of entanglement. It consists of two distant (two-level) atoms which interact through a radiation field and becomes entangled. We…
Dynamical creation of entanglement by homodyne-mediated feedback
Jin Wang, H. M. Wiseman, G. J. Milburn
For two two-level atoms coupled to a single-mode cavity field that is driven and heavily damped, the steady-state can be entangled by shining an un-modulated driving laser on the s…
Bayesian feedback versus Markovian feedback in a two-level atom
H. M. Wiseman, Stefano Mancini, Jin Wang
We compare two different approaches to the control of the dynamics of a continuously monitored open quantum system. The first is Markovian feedback as introduced in quantum optics…
Non-Markovian homodyne-mediated feedback on a two-level atom: a quantum trajectory treatment
Jin Wang, H. M. Wiseman, G. J. Milburn
Quantum feedback can stabilize a two-level atom against decoherence (spontaneous emission), putting it into an arbitrary (specified) pure state. This requires perfect homodyne dete…
