An adaptive-size multi-domain pseudospectral approach for solving the time-dependent Schrödinger equation
R. Esteban Goetz, Andrea Simoni, Christiane P. Koch
We show that a pseudospectral representation of the wavefunction using multiple spatial domains of variable size yields a highly accurate, yet efficient method to solve the time-de…
Theoretical description of circular dichroism in photoelectron angular distributions of randomly oriented chiral molecules after multi-photon photoionization
R. E. Goetz, T. A. Isaev, B. Nikoobakht +2
Photoelectron circular dichroism refers to the forward/backward asymmetry in the photoelectron angular distribution with respect to the propagation axis of circularly polarized lig…
Maximizing Hole Coherence in Ultrafast Photoionization of Argon with SPA-Optimization
R. Esteban Goetz, Maximilian Merkel, Antonia Karamatskou +2
Photoionization with attosecond pulses populates hole states in the photoion. Superpositions of hole states represent ideal candidates for time-dependent spectroscopy, for example…
Hybrid benchmarking of arbitrary quantum gates
Tobias Chasseur, Daniel M. Reich, Christiane P. Koch +1
We present a protocol for Interleaved Randomized Benchmarking of arbitrary quantum gates using Monte Carlo sampling of quantum states. It is generally applicable, including non-Cli…
Charting the circuit QED design landscape using optimal control theory
Michael H. Goerz, Felix Motzoi, K. Birgitta Whaley +1
With recent improvements in coherence times, superconducting transmon qubits have become a promising platform for quantum computing. They can be flexibly engineered over a wide ran…
Controlling open quantum systems: Tools, achievements, and limitations
Christiane P. Koch
The advent of quantum devices, which exploit the two essential elements of quantum physics, coherence and entanglement, has sparked renewed interest in the control of open quantum…
