Approximating open quantum system dynamics in a controlled and efficient way: A microscopic approach to decoherence
Giulia Gualdi, Christiane P. Koch
We demonstrate that the dynamics of an open quantum system can be calculated efficiently and with predefined error, provided a basis exists in which the system-environment interact…
Generating Molecular Rovibrational Coherence by Two-Photon Femtosecond Photoassociation of Thermally Hot Atoms
Leonid Rybak, Saieswari Amaran, Liat Levin +5
The formation of diatomic molecules with rotational and vibrational coherence is demonstrated experimentally in free-to-bound two-photon femtosecond photoassociation of hot atoms.…
Prospects for fast Rydberg gates on an atom chip
Matthias M. Müller, Harald R. Haakh, Tommaso Calarco +2
Atom chips are a promising candidate for a scalable architecture for quantum information processing provided a universal set of gates can be implemented with high fidelity. The dif…
Optimizing entangling quantum gates for physical systems
M. M. Müller, D. M. Reich, M. Murphy +5
Optimal control theory is a versatile tool that presents a route to significantly improving figures of merit for quantum information tasks. We combine it here with the geometric th…
The Quantum Speed Limit of Optimal Controlled Phasegates for Trapped Neutral Atoms
Michael H. Goerz, Tommaso Calarco, Christiane P. Koch
We study controlled phasegates for ultracold atoms in an optical potential. A shaped laser pulse drives transitions between the ground and electronically excited states where the a…
