Conditions for Equivalent Noise Sensitivity of Geometric and Dynamical Quantum Gates

PRX Quantum, 2022
Geometric quantum gates are often expected to be more resilient than dynamical gates against certain types of error, which would make them ideal for robust quantum computing.

Controlled invariance for hamiltonian systems [PDF]

, 1985
A notion of controlled invariance is developed which is suited to Hamiltonian control systems. This is done by replacing the controlled invariantdistribution, as used for general nonlinear control systems, by the controlled invariantfunction group. It is

Analytical Approximation Methods for the Stabilizing Solution of the Hamilton–Jacobi Equation [PDF]

, 2007
In this paper, two methods for approximating the stabilizing solution of the Hamilton–Jacobi equation are proposed using symplectic geometry and a Hamiltonian perturbation technique as well as stable manifold theory.

Quantum optimal control theory for solvated systems. [PDF]

Journal of Chemical Physics, 2019
In this work, we generalize the quantum optimal control theory (QOCT) of molecules subject to ultrashort laser pulses to the case of solvated systems, explicitly including the solvent dielectric properties in the system's quantum Hamiltonian.
