Optical control of the complex phase of a quantum ground state amplitude
Adam Kinos, Mogens Dalgaard, Klaus Mølmer
We discuss how coherent driving of a two-level quantum system can be used to induce a complex phase on the ground state and we discuss its geometric and dynamic contributions. Whil…
Fast, high precision dynamics in quantum optimal control theory
Mogens Dalgaard, Felix Motzoi
Quantum optimal control theory is becoming increasingly crucial as quantum devices become more precise, but the need to quickly optimize these systems classically remains a signifi…
Dynamical uncertainty propagation with noisy quantum parameters
Mogens Dalgaard, Carrie A. Weidner, Felix Motzoi
Many quantum technologies rely on high-precision dynamics, which raises the question of how these are influenced by the experimental uncertainties that are always present in real-l…
Predicting quantum dynamical cost landscapes with deep learning
Mogens Dalgaard, Felix Motzoi, Jacob Sherson
State-of-the-art quantum algorithms routinely tune dynamically parametrized cost functionals for combinatorics, machine learning, equation-solving, or energy minimization. However,…
Hessian-based optimization of constrained quantum control
Mogens Dalgaard, Felix Motzoi, Jesper Hasseriis Mohr Jensen +1
Efficient optimization of quantum systems is a necessity for reaching fault tolerant thresholds. A standard tool for optimizing simulated quantum dynamics is the gradient-based \te…
Global optimization of quantum dynamics with AlphaZero deep exploration
Mogens Dalgaard, Felix Motzoi, Jens Jakob Sorensen +1
While a large number of algorithms for optimizing quantum dynamics for different objectives have been developed, a common limitation is the reliance on good initial guesses, being…
Quantum Control with Measurements and Quantum Zeno Dynamics
Jens Jakob Sørensen, Mogens Dalgaard, Alexander Holm Kiilerich +2
We introduce an efficient iterative method to prepare a target state in Hilbert spaces with high dimensionality using a combination of unitary evolution, measurements, and quantum…
