Many-body gap protection of motional dephasing of an optical clock transition

Zhijing Niu, Vera M. Schäfer, Haoqing Zhang +7

Quantum simulation and metrology with atoms, ions, and molecules often rely on using light fields to manipulate their internal states. The absorbed momentum from the light fields c…

Time-resolved pairing gap spectroscopy in a quantum simulator of fermionic superfluidity inside an optical cavity

Dylan J. Young, Eric Yilun Song, Anjun Chu +6

We use an ensemble of laser-cooled strontium atoms in a high-finesse cavity to cleanly emulate the technique of rf spectroscopy employed in studies of BEC-BCS physics in fermionic…

Cold highly charged ions in a radio-frequency trap with superconducting magnetic shielding

Elwin A. Dijck, Christian Warnecke, Malte Wehrheim +12

We implement sympathetic cooling of highly charged ions (HCI) by fully enclosing a linear Paul trap within a superconducting radio-frequency resonator. A quantization magnetic fiel…

Observing dynamical phases of BCS superconductors in a cavity QED simulator

Dylan J. Young, Anjun Chu, Eric Yilun Song +7

In conventional Bardeen-Cooper-Schrieffer (BCS) superconductors, electrons with opposite momenta bind into Cooper pairs due to an attractive interaction mediated by phonons in the…

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…

Quantum computing hardware in the cloud: Should a computational chemist care?

A. Rossi, P. G. Baity, V. M. Schäfer +1

Within the last decade much progress has been made in the experimental realisation of quantum computing hardware based on a variety of physical systems. Rapid progress has been fue…

Magnetic field stabilization system for atomic physics experiments

B. Merkel, K. Thirumalai, J. E. Tarlton +4

Atomic physics experiments commonly use millitesla-scale magnetic fields to provide a quantization axis. As atomic transition frequencies depend on the amplitude of this field, man…

Optical injection and spectral filtering of high-power UV laser diodes

V. M. Schäfer, C. J. Ballance, C. J. Tock +1

We demonstrate injection-locking of 120mW laser diodes operating at 397nm. We achieve stable operation with injection powers of ~100uW and a slave laser output power of up to 110mW…

Hybrid quantum logic and a test of Bell's inequality using two different atomic isotopes

C. J. Ballance, V. M. Schaefer, J. P. Home +9

Entanglement is one of the most fundamental properties of quantum mechanics, and is the key resource for quantum information processing. Bipartite entangled states of identical par…
