Quantum metrology with full and fast quantum control [PDF]
Quantum, 2017 We establish general limits on how precise a parameter, e.g. frequency or the strength of a magnetic field, can be estimated with the aid of full and fast quantum control.

Optimal quantum control of charging quantum batteries [PDF]
New Journal of Physics, 2022 Abstract Quantum control allows us to address the problem of engineering quantum dynamics for special purposes. While recently the field of quantum batteries has attracted much attention, optimization of their charging has not benefited from the quantum control methods. Here we fill this gap by using an optimization method.

Light quantum control of persisting Higgs modes in iron-based superconductors. [PDF]
Nat Commun, 2021 The Higgs mechanism, i.e., spontaneous symmetry breaking of the quantum vacuum, is a cross-disciplinary principle, universal for understanding dark energy, antimatter and quantum materials, from superconductivity to magnetism.

The advantage of quantum control in many-body Hamiltonian learning [PDF]
Quantum, 2023 We study the problem of learning the Hamiltonian of a many-body quantum system from experimental data. We show that the rate of learning depends on the amount of control available during the experiment.

Quantum control of a nanoparticle optically levitated in cryogenic free space [PDF]
Nature, 2021 Tests of quantum mechanics on a macroscopic scale require extreme control over mechanical motion and its decoherence1–3. Quantum control of mechanical motion has been achieved by engineering the radiation–pressure coupling between a micromechanical ...

Quantum Control of a Single Magnon in a Macroscopic Spin System. [PDF]
Physical Review Letters, 2022 Nonclassical quantum states are the pivotal features of a quantum system that differs from its classical counterpart. However, the generation and coherent control of quantum states in a macroscopic spin system remain an outstanding challenge.

Model-Free Quantum Control with Reinforcement Learning [PDF]
Physical Review X, 2021 Model bias is an inherent limitation of the current dominant approach to optimal quantum control, which relies on a system simulation for optimization of control policies.

Analog Quantum Control of Magnonic Cat States on a Chip by a Superconducting Qubit. [PDF]
Physical Review Letters, 2022 We propose to directly and quantum-coherently couple a superconducting transmon qubit to magnons-the quanta of the collective spin excitations, in a nearby magnetic particle.
