Demonstration of Parallel Multi-QPU Execution for Fragment-Based Quantum Chemistry Using On-Premises Hardware
Nils Herrmann, Mariam Akhtar, Luke W. Bertels +21
Fragment molecular orbital (FMO) quantum chemistry offers a natural route to parallel quantum computing: large molecular calculations can be decomposed into smaller quantum subprob…
Deterministic quantum state transfer of atoms in a random magnetic field
Bianca J. Sawyer, Matthew Chilcott, Ryan Thomas +2
We propose a method for transferring atoms to a target quantum state for a multilevel quantum system with sequentially increasing, but otherwise unknown, energy splitting. This is…
Quantum Scattering in an Optical Collider for Ultracold Atoms
Ryan Thomas, Matthew Chilcott, Craig Chisholm +4
We report on experiments investigating the collisional properties of atoms at ultralow collision energies using an all-optical atom collider. By using a pair of optical tweezers, w…
Dispersive optical detection of magnetic Feshbach resonances in ultracold gases
Bianca J. Sawyer, Milena S. J. Horvath, Eite Tiesinga +2
Magnetically tunable Feshbach resonances in ultracold atomic systems are chiefly identified and characterized through time consuming atom loss spectroscopy. We describe an off-reso…
Dispersive probing of driven pseudo-spin dynamics in a gradient field
Amita B. Deb, Bianca J. Sawyer, Niels Kjærgaard
We have studied the coherent evolution of ultracold atomic rubidium clouds subjected to a microwave field driving Rabi oscillations between the stretched states of the F=1 and F=2…
Reducing number fluctuations of ultracold atomic gases via dispersive interrogation
Bianca J. Sawyer, Amita B. Deb, Thomas McKellar +1
We have used nondestructive laser probing to follow the central density evolution of a trapped atomic cloud during forced evaporative cooling. This was achieved in a heterodyne dis…
A laser based accelerator for ultracold atoms
A. Rakonjac, A. B. Deb, S. Hoinka +3
We present first results on our implementation of a laser based accelerator for ultracold atoms. Atoms cooled to a temperature of 420 nK are confined and accelerated by means of la…
