Welcome to the Rydberg Quantum Devices team lead by Dr. Jonathan Pritchard, an EPSRC Quantum Technology Fellow at the University of Strathclyde.


Rydberg atoms are atoms excited to extremely large principal quantum numbers resulting in giant atoms offering exaggerated properties including enormous electric-dipole moments in the microwave frequency range. Our research is focused on developing new quantum technologies that exploit these Rydberg atomic dipoles via coupling to superconducting circuits in a hybrid approach to quantum information processing and in developing atomic gas sensors for precision microwave field detection and imaging.

Please contact jonathan.pritchard@strath.ac.uk if you are interested in working in within one of our research areas – we have both PhD and PDRA Positions Currently Available for a new project developing a a neutral atom quantum computer based on scalable arrays of neutral atoms.


Scalable Qubit Arrays for Quantum Computing and Optimisation

This project seeks to establish a novel platform for quantum computing based on scalable arrays of neutral atoms. The project, will develop new hardware to cool and trap arrays of over 100 qubits that will be used to perform both analogue and digital quantum simulation by exploiting the strong long-range interactions of highly excited Rydberg atoms.

We are seeking highly motivated experimental researchers for both Postdoctoral Researchers and PhD positions on this project.


Hybrid Quantum Interface – Atoms coupled to superconductors

HQT200x200 This project seeks to develop next-generation hardware for quantum networking by using atomic ensembles coupled to superconducting microwave circuits to generate, store and entangle photons in a single chip-based device. This offers a direct route to the creation of scalable quantum networks, in addition to future integration with ultra-fast superconducting qubits to enable distributed quantum computing.

Microwave Field Sensing using Rydberg atoms

RF fields in the microwave and terahertz domain are ubiquitous for security and communications, however test equipment requires frequent recalibration and careful understanding of the perturbations caused by the antenna used for measurement. This new project, a collaboration between Strathclyde, Durham and NPL, seeks to develop new all-optical field sensors operating in the microwave and terahertz domain using Rydberg atoms in a thermal vapour to act as microscopic antenna enabling metal-free probing, sub-wavelength imaging resolution and the ability to implement a traceable SI calibration offering superior sensitivity compared to existing technologies.
