Gaussian theory for estimating fluctuating perturbations with back action evasive oscillator variables
Jesper Hasseriis Mohr Jensen, Klaus Mølmer
We apply a Gaussian state formalism to track fluctuating perturbations that act on the position and momentum quadrature variables of a harmonic oscillator. Following a seminal prop…
Student use of a quantum simulation and visualization tool
Shaeema Zaman Ahmed, Carrie A. Weidner, Jesper H. M. Jensen +2
Knowledge of quantum mechanical systems is becoming more important for many science and engineering students who are looking to join the emerging quantum workforce. To better prepa…
A training programme for early-stage researchers that focuses on developing personal science outreach portfolios
Shaeema Zaman Ahmed, Arthur Hjorth, Janet Frances Rafner +6
Development of outreach skills is critical for researchers when communicating their work to non-expert audiences. However, due to the lack of formal training, researchers are typic…
Achieving fast high-fidelity optimal control of many-body quantum dynamics
Jesper Hasseriis Mohr Jensen, Frederik Skovbo Møller, Jens Jakob Sørensen +1
We demonstrate the efficiency of a recent exact-gradient optimal control methodology by applying it to a challenging many-body problem, crossing the superfluid to Mott-insulator ph…
Quantum Composer: A programmable quantum visualization and simulation tool for education and research
Shaeema Zaman Ahmed, Jesper Hasseriis Mohr Jensen, Carrie Ann Weidner +3
Making quantum mechanical equations and concepts come to life through interactive simulation and visualization are commonplace for augmenting learning and teaching. However, graphi…
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…
