Multi-color quantum control for suppressing ground state coherences in two-dimensional electronic spectroscopy
J. Lim, C. M. Bösen, A. D. Somoza +3
The measured multi-dimensional spectral response of different light harvesting complexes exhibits oscillatory features which suggest an underlying coherent energy transfer. However…
Quantum control of molecular rotation
Christiane P. Koch, Mikhail Lemeshko, Dominique Sugny
The angular momentum of molecules, or, equivalently, their rotation in three-dimensional space, is ideally suited for quantum control. Molecular angular momentum is naturally quant…
Transient Non-Confining Potentials for Speeding Up a Single Ion Heat Pump
E. Torrontegui, S. T. Dawkins, M. Göb +1
We propose speeding up a single ion heat pump based on a tapered ion trap. If a trapped ion is excited in an oscillatory motion axially the radial degrees of freedom are cyclically…
Quantum control of photoelectron circular dichroism
R. Esteban Goetz, Christiane P. Koch, Loren Greenman
We demonstrate coherent control over the photoelectron circular dichroism in randomly oriented chiral molecules, based on quantum interference between multiple photoionization path…
Controlling ultracold -wave collisions with non-resonant light: Predictions of an asymptotic model for the generalized scattering volume
Anne Crubellier, Rosario González-Férez, Christiane P. Koch +1
Interactions in a spin-polarized ultracold Fermi gas are governed by -wave collisions and can be characterized by the -wave scattering volume. Control of these collisions by…
Defining the -wave scattering volume in the presence of dipolar interactions
Anne Crubellier, Rosario González-Férez, Christiane P. Koch +1
The definition of the scattering volume for -wave collisions needs to be generalized in the presence of dipolar interactions for which the potential decreases with the interpart…
Quantum optimal control of the dissipative production of a maximally entangled state
Karl P. Horn, Florentin Reiter, Yiheng Lin +2
Entanglement generation can be robust against noise in approaches that deliberately incorporate dissipation into the system dynamics. The presence of additional dissipation channel…
Optimized Sampling of Mixed-State Observables
Marec W. Heger, Christiane P. Koch, Daniel M. Reich
Quantum dynamical simulations of statistical ensembles pose a significant computational challenge due to the fact that mixed states need to be represented. If the underlying dynami…
Quantum Optimal Control for Mixed State Squeezing in Cavity Optomechanics
Daniel Basilewitsch, Christiane P. Koch, Daniel M. Reich
The performance of key tasks in quantum technology, such as accurate state preparation, can be maximized by utilizing external controls and deriving their shape with optimal contro…
Optimal storage of a single photon by a single intra-cavity atom
Luigi Giannelli, Tom Schmit, Tommaso Calarco +3
We theoretically analyse the efficiency of a quantum memory for single photons. The photons propagate along a transmission line and impinge on one of the mirrors of a high-finesse…
Dissipative Quantum Dynamics and Optimal Control using Iterative Time Ordering: An Application to Superconducting Qubits
Daniel Basilewitsch, Lutz Marder, Christiane P. Koch
We combine a quantum dynamical propagator that explicitly accounts for quantum mechanical time ordering with optimal control theory. After analyzing its performance with a simple m…
Fast and accurate circularization of a Rydberg atom
Sabrina Patsch, Daniel M. Reich, Jean-Michel Raimond +3
Preparation of a so-called circular state in a Rydberg atom where the projection of the electron angular momentum takes its maximum value is challenging due to the required amount…
