Switching Rydberg interactions by three orders of magnitude using a terahertz field

Karen Wadenpfuhl, Aaron Reinhard, Oliver Hughes +3

Atom-based quantum computing exploits the ability to enhance atom-atom interactions by employing laser excitation to higher-excited Rydberg states. Additional fields that drive tra…

Temporally-multiplexed dual-frequency terahertz imaging at kilohertz frame rates

Lucy A. Downes, C. Stuart Adams, Kevin J. Weatherill

We present a temporally-multiplexed dual-colour terahertz (THz) imaging technique using THz-to-optical conversion in atomic vapour. By rapidly alternating the pump laser frequency,…

Virtually structured illumination for terahertz super-resolution imaging

James P. Fleming, Lucy A. Downes, John M. Girkin +1

We demonstrate structured illumination super-resolution imaging in the Terahertz (THz) frequency band using the Virtually Structured Detection (VSD) method. Leveraging our previous…

Determination of Quantum Defects and Core Polarizability of Atomic Cesium via Terahertz and Radio-Frequency Spectroscopy in Thermal Vapor

Gianluca Allinson, Lucy A. Downes, Kevin J. Weatherill +1

We present new measurements of quantum defects and core polarizabilities in cesium (Cs), based on transition frequency measurements between Rydberg states ($14 \leq n \leq…

Simultaneous multi-band radio-frequency detection using high-orbital-angular-momentum states in a Rydberg-atom receiver

Gianluca Allinson, Matthew J. Jamieson, Lucy Downes +3

We demonstrate simultaneous detection of radio-frequency (RF) fields ranging from the very high-frequency (VHF) band (128 MHz) to terahertz frequencies (0.61 THz) using a caesium R…

Simple Python tools for modelling few-level atom-light interactions

Lucy Downes

Understanding the interactions between atoms and light is at the heart of atomic physics. Being able to `experiment' with various system parameters, produce plots of the results an…
