High-fidelity state transfer between leaky quantum memories
Physical Review Research, 2021 Employing the scattering-Lindblad-Hamiltonian formalism description of quantum network theory, we model the general problem of quantum state transfer between two disparate quantum memory blocks in an open quantum system.

Analysis of Lyapunov Control for Hamiltonian Quantum Systems [PDF]
Proceedings of ENOC 2008 (St Petersburg, Russia, June 30-July 4,
2008), http://lib.physcon.ru/?item=1761, 2008 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's invariance principle and stability analysis from dynamical systems and control theory.

Bilinear dynamic mode decomposition for quantum control
New Journal of Physics, 2021 Data-driven methods for establishing quantum optimal control (QOC) using time-dependent control pulses tailored to specific quantum dynamical systems and desired control objectives are critical for many emerging quantum technologies.

A Hamiltonian approach to sufficiency in optimal control with minimal regularity conditions: Part I [PDF]
arXiv, 2015 In this paper we develop a Hamiltonian approach to sufficient conditions in optimal control problems. We extend the known conditions for $C^2$ maximised Hamiltonians into two directions: on the one hand we explain the role of a super Hamiltonian (i.e. a Hamiltonian which is greater then or equal to the maximised one) on the other we develop the theory ...

Representation of convex Hamilton-Jacobi equations in optimal control theory [PDF]
arXiv, 2015 In the paper we study the following problem: given a Hamilton-Jacobi equation where the Hamiltonian is convex with respect to the last variable, are there any optimal control problems representing it? In other words, we search for an appropriately regular dynamics and a Lagrangian that represents the Hamiltonian with given properties.

Adiabatic and Hamiltonian computing on a 2D lattice with simple 2-qubit interactions [PDF]
, 2015 We show how to perform universal Hamiltonian and adiabatic computing using a time-independent Hamiltonian on a 2D grid describing a system of hopping particles which string together and interact to perform the computation. In this construction, the movement of one particle is controlled by the presence or absence of other particles, an effective ...

High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy
Physical Review X, 2018 We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high-spectral-resolution nuclear magnetic resonance (NMR) spectroscopy.
