Continuous momentum state lasing and cavity frequency-pinning with laser-cooled strontium atoms
V. M. Schäfer, Z. Niu, J. R. K. Cline +4
Laser-cooled gases of atoms interacting with the field of an optical cavity are a powerful tool for quantum sensing and the simulation of open and closed quantum systems. They can…
Financial Risk Management on a Neutral Atom Quantum Processor
Lucas Leclerc, Luis Ortiz-Guitierrez, Sebastian Grijalva +19
Machine Learning models capable of handling the large datasets collected in the financial world can often become black boxes expensive to run. The quantum computing paradigm sugges…
Quantum Feature Maps for Graph Machine Learning on a Neutral Atom Quantum Processor
Boris Albrecht, Constantin Dalyac, Lucas Leclerc +10
Using a quantum processor to embed and process classical data enables the generation of correlations between variables that are inefficient to represent through classical computati…
Continuous collective strong coupling between atoms and a high finesse optical cavity
Julia R. K. Cline, Vera M. Schäfer, Zhijing Niu +3
We demonstrate continuous loading of strontium atoms into a high finesse ring cavity and observe continuous strong collective coupling in the form of a vacuum Rabi splitting betwee…
A cavity-QED quantum simulator of dynamical phases of a BCS superconductor
Robert J. Lewis-Swan, Diego Barberena, Julia R. K. Cline +3
We propose to simulate dynamical phases of a BCS superconductor using an ensemble of cold atoms trapped in an optical cavity. Effective Cooper pairs are encoded via internal states…
Cavity-QED determination of the natural linewidth of the Sr millihertz clock transition with 30Hz resolution
Juan A. Muniz, Dylan J. Young, Julia R. K. Cline +1
We present a new method for determining the intrinsic natural linewidth or lifetime of exceptionally long-lived optical excited states. Such transitions are key to the performance…
