QEngine: An open-source C++ Library for Quantum Optimal Control of Ultracold Atoms
Jens Jakob Sørensen, Jesper Jensen, Till Heinzel +1
We present the first version of the QEngine, an open-source C++ library for simulating and controlling ultracold quantum systems using optimal control theory (OCT). The most notabl…
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…
Approaching the Quantum Speed Limit with Global-Local Optimization
Jens Jakob Sørensen, Mikel Aranburu, Till Heinzel +1
We propose a Global-Local optimization algorithm for quantum control that combines standard local search methodologies with evolutionary algorithms. This allows us to find faster s…
Quantum Optimal Control in a Chopped Basis: Applications in Control of Bose-Einstein Condensates
Jens Jakob Sørensen, Mikel Aranburu, Till Heinzel +1
We discuss quantum optimal control of Bose-Einstein condensates trapped in magnetic microtraps. The objective is to transfer a condensate from the ground state to the first-excited…
