Transverse-field Ising Dynamics by Rydberg Dressing in a Cold Dilute Gas (QTh5B.1)
Presenter: Victoria Borish, Stanford University

Rydberg dressing provides optically controllable interactions between neutral atoms, of interest for generating many-body entanglement. We demonstrate these interactions and emulate transverse-field Ising dynamics in a cold gas of cesium atoms.

Experimental Demonstration of a Reconfigurable Entangled Radiofrequency-Photonic Sensor Network (QTh5B.2)
Presenter: Yi Xia, University of Arizona

We propose and experimentally demonstrate a reconfigurable radiofrequency (RF)-photonic sensor network comprised of three entangled sensor nodes to increase the precision of parameter estimation in networked RF sensing tasks.

Tools of Optimal Control for the Design of Robust Atom Interferometers (QTh5B.3)
Presenter: Michael Goerz, Army Research Lab

We examine the robustness of analytic pulse schemes for atomic fountain interferometers with respect to pulse amplitude and initial velocity distribution and design new robust schemes using numerical optimal control theory.

Real-Time Charge Control of Diamond Quantum Sensors (QTh5B.4)
Presenter: David Hopper, University of Pennsylvania

We use real-time feedback to deterministically initialize a nitrogen-vacancy’s charge state at room temperature, and demonstrate improved spin readout efficiency resulting in a factor-of-20 speedup for a typical quantum sensing experiment.

Opticlock: Transportable and Easy-to-Operate Optical Single-Ion Clock (QTh5B.6)
Presenter: Stephan Ritter, TOPTICA Photonics AG

A robust optical clock was developed; integrated into two mobile 19” rack assemblies and based on the 2S1/2-2D3/2 transition of a single 171Yb+ ion. The system design and a first complete evaluation will be discussed.
