Quantum System Identification by Bayesian Analysis of Noisy Data: Beyond Hamiltonian Tomography
S. G. Schirmer, D. K. L. Oi
We consider how to characterize the dynamics of a quantum system from a restricted set of initial states and measurements using Bayesian analysis. Previous work has shown that Hami…
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…
Two-Qubit Hamiltonian Tomography by Bayesian Analysis of Noisy Data
S. G. Schirmer, D. K. L. Oi
We present an empirical strategy to determine the Hamiltonian dynamics of a two-qubit system using only initialization and measurement in a single fixed basis. Signal parameters ar…
Implementation of Quantum Gates via Optimal Control
Sonia Schirmer
Starting with the basic control system model often employed in NMR pulse design, we derive more realistic control system models taking into account effects such as off-resonant exc…
Analysis of Lyapunov Control for Hamiltonian Quantum Systems
Xiaoting Wang, Sonia Schirmer
We present detailed analysis of the convergence properties and effectiveness of Lyapunov control design for bilinear Hamiltonian quantum systems based on the application of LaSalle…
Physics-based mathematical models for quantum devices via experimental system identification
Sonia Schirmer, Daniel Oi, Simon Devitt
We consider the task of intrinsic control system identification for quantum devices. The problem of experimental determination of subspace confinement is considered, and simple gen…
