Triggering recollisions with XUV pulses: Imprint of recolliding periodic orbits
Jonathan Dubois, Angel Jorba
We consider an electron in an atom driven by an infrared (IR) elliptically polarized laser field after its ionization by an ultrashort extreme ultraviolet (XUV) pulse. We find that…
Quandary: An open-source C++ package for high-performance optimal control of open quantum systems
Stefanie Günther, N. Anders Petersson, Jonathan L. Dubois
Quantum optimal control can be used to shape the control pulses for realizing unitary and non-unitary transformations of quantum states. These control pulses provide the fundamenta…
Bogolyubov's averaging theorem applied to the Kramers-Henneberger Hamiltonian
Elena Floriani, Jonathan Dubois, Cristel Chandre
We apply Bogolyubov's averaging theorem to the motion of an electron of an atom driven by a linearly polarized laser field in the Kramers-Henneberger frame. We provide estimates of…
Quantum Optimal Control for Pure-State Preparation Using One Initial State
Stefanie Günther, N. Anders Petersson, Jonathan L. DuBois
This paper presents a framework for solving the pure-state preparation problem using numerical optimal control. As an example, we consider the case where a number of qubits are dis…
Low frequency correlated charge noise measurements across multiple energy transitions in a tantalum transmon
Daniel M. Tennant, Luis A. Martinez, Kristin M. Beck +5
Transmon qubits fabricated with tantalum metal have been shown to possess energy relaxation times greater than 300 s and, as such, present an attractive platform for high precis…
Dynamical organization of recollisions by a family of invariant tori
Jonathan Dubois, Marc Jorba-Cusco, {À}ngel Jorba +1
We consider the motion of an electron in an atom subjected to a strong linearly polarized laser field. We identify the invariant structures organizing a very specific subset of tra…
