Pulse engineering via projection of response functions at infinite nonlinear order
Lia Kley, Ludwig Mathey
Optimal control problems arise in a wide range of scientific disciplines, but the corresponding optimization algorithms often display a strong dependence on hyperparameters that si…
Fermionic Hamiltonian engineering with local control
Ãzgün Kum, Matthias Zipper, Ludwig Mathey +1
Quantum simulators enable the exploration of complex quantum phenomena in condensed-matter systems by reproducing their dynamics on controllable quantum devices. However, experimen…
Fluctuation amplification engineering in multimode Raman-cavity systems
H. P. Ojeda Collado, Ludwig Mathey
Parametric amplification is a key ingredient of a wide range of phenomena, from the classical to the quantum domain. Although such phenomena have been demonstrated in non-equilibri…
Lamb-Dicke Dynamics of Interacting Rydberg Atoms Coupled to the Motion of an Optical Tweezer Array
Aslam Parvej, Ludwig Mathey
Neutral Rydberg atoms trapped in optical tweezer arrays provide a platform for quantum simulation and computation. In this work, we investigate the Lamb-Dicke dynamics of coupled R…
Pulse engineering via projection of response functions
Nicolas Heimann, Lukas Broers, Ludwig Mathey
We present an iterative optimal control method of quantum systems, aimed at an implementation of a desired operation with optimal fidelity. The update step of the method is based o…
Optimal recoil-free state preparation in an optical atom tweezer
Lia Kley, Nicolas Heimann, Aslam Parvej +2
Quantum computing in atom tweezers requires high-fidelity implementations of quantum operations. Here, we demonstrate the optimal implementation of the transition $|0\rangle \right…
