Quantum mechanics, control theory and quantum control
Transactions of the Institute of Measurement and Control, 2008This paper provides a brief review of Rosenbrock's recent work on generating quantum mechanics using dynamic programming, some background knowledge of quantum mechanics and some general issues and problems in developing feedback quantum control.

A shortcut tour of quantum control methods for modern quantum technologies
Europhysics letters, 2020Quantum control methods, like rapid adiabatic passage, stimulated Raman adiabatic passage, shortcuts to adiabaticity and optimal control, have become an integral part of modern quantum technologies, for example quantum computation and sensing, where they

Quantum 2.0 Conference and Exhibition
We demonstrate a new method for optimal bidirectional control of complex physical systems. Employing a set of collaborative neural networks, our approach exhibits unprecedented accuracy, even at the single-photon level.

Measurement-based quantum control of mechanical motion
Nature, 2018Controlling a quantum system by using observations of its dynamics is complicated by the backaction of the measurement process—that is, the unavoidable quantum disturbance caused by coupling the system to a measurement apparatus. An efficient measurement

Quantum control of surface acoustic-wave phonons
Nature, 2018One of the hallmarks of quantum physics is the generation of non-classical quantum states and superpositions, which has been demonstrated in several quantum systems, including ions, solid-state qubits and photons. However, only indirect demonstrations of

Tunable lasers, sources of intense narrow-band coherent radiation, enabled the parity violation experiments in atoms in the 1970’s. Ultrafast lasers are source of broadband coherent radiation. This paper reviews recent progress in experiments to control quantum dynamics in condensed phase and gas phase systems, using shaped ultrafast radiation. Many of

Remote-controlled quantum computing by quantum entanglement
Optics Letters, 2020Quantum entanglement enables measurement on one party to affect the other’s state. Based on this peculiar feature, we propose a model of remote-controlled quantum computing and design an optical scheme to realize this model for a single qubit.

Mathematical Models and Methods in Applied Sciences, 1999
We propose a new control method for systems whose evolution is described by Schrödinger's equation (quantum dynamics). The goal of the control is to induce modifications of observable quantities — with possible effects at mesoscopic or macroscopic levels — by modifying the potential at the microscopic level.

Pathways to New Applications for Quantum Control.
Accounts of Chemical Research, 2018In 1998, the first successful quantum control experiment with application to a molecular framework was conducted with a shaped laser pulse, optimizing the branching ratio between different organometallic reaction channels.
