Robust Entanglement in Anti-ferromagnetic Heisenberg Chains by Single-spin Optimal Control
Xiaoting Wang, Abolfazl Bayat, Sophie G Schirmer +1
We demonstrate how near-perfect entanglement (in fact arbitrarily close to maximal entanglement) can be generated between the end spins of an anti-ferromagnetic isotropic Heisenber…
Stabilizing Quantum States by Constructive Design of Open Quantum Dynamics
Francesco Ticozzi, Sophie G. Schirmer, Xiaoting Wang
Based on recent work on the asymptotic behavior of controlled quantum Markovian dynamics, we show that any generic quantum state can be stabilized by devising constructively a simp…
Stabilizing Open Quantum Systems by Markovian Reservoir Engineering
S. G. Schirmer, Xiaoting Wang
We study open quantum systems whose evolution is governed by a master equation of Kossakowski-Gorini-Sudarshan-Lindblad type and give a characterization of the convex set of steady…
Entanglement generation between distant atoms by Lyapunov control
Xiaoting Wang, S. G. Schirmer
We show how to apply Lyapunov control design to the problem of entanglement creation between two atoms in distant cavities connected by optical fibers. The Lyapunov control design…
On the Contractivity of Hilbert-Schmidt distance under open system dynamics
Xiaoting Wang, Sonia Schirmer
We show that the Hilbert-Schmidt distance, unlike the trace distance, between quantum states is generally not monotonic for open quantum systems subject to Lindblad semigroup dynam…
Analysis of Effectiveness of Lyapunov Control for Non-generic Quantum States
Xiaoting Wang, Sonia Schirmer
A Lyapunov-based control design for natural trajectory-tracking problems is analyzed for quantum states where the analysis in the generic case is not applicable. Using dynamical sy…
