Universal Quantum · Haywards Heath

Designs and simulates quantum error correction protocols, tailoring them to hardware strengths and characterising physical qubit noise profiles. Performs resource estimation for large-scale applications and advises on hardware and software control choices to optimise error correction performance in the near and far term.

Universal Quantum · Haywards Heath

Design and develop next-generation microfabricated Paul traps for scalable quantum computers, working with users to determine suitable layouts and acting as technical liaison with ion trap manufacturers. Perform electromagnetic and thermo-mechanical analysis and simulation, and collaborate with package designers on assembly procedures. The role also involves documenting designs and simulations.

IonQ · Oxford

Validates and optimises trapped-ion quantum computers, prototyping coherent control and cooling schemes, calibrating and benchmarking qubit gates, and validating emerging trap technologies with integrated electronics and photonics. Involves coding and debugging experiments in Python or Rust and documenting findings within a fast-moving UK science team.

Rigetti · Berkeley, United States · US$190,000 – US$225,000 pa

Lead a cross-functional team building next-generation superconducting quantum hardware, proposing new technical directions and designing experiments to improve performance and scalability. Own delivery of key quantum technologies, using cryogenic systems, RF and time-domain measurement, and Python to close performance gaps.

Rigetti · Berkeley, United States · US$175,000 – US$200,000 pa

Lead experimental programs to characterize, calibrate and optimize two-qubit gates on tunable-coupler superconducting processors, isolating error sources such as leakage, crosstalk and decoherence. Develop pulse shaping, dynamical decoupling and automated calibration methods that scale across hundreds of qubit pairs, feeding findings back into device design and fabrication.

University of Sussex · Brighton

Postdoctoral role in experimental quantum technology, combining trapped ions and photons to build a distributed quantum network. The work involves testing and characterising a multi-zone ion trap, implementing an efficient ion-photon interface based on strongly-coupled cavity-QED, and setting up a second system for a basic quantum network. The position sits within the EPSRC Quantum Technology Hub and a team led by Prof Matthias Keller.

Infleqtion · Kidlington

Experimental AMO physicist role focused on translating product requirements into atomic system designs for quantum RF sensor systems. Involves modelling, simulation, testing and integrating opto-mechanical systems, electronics and software into quantum devices, working closely with a multidisciplinary team of physicists and engineers.

Imperial College London · London · £50,733 – £62,001 pa

Designs optimised driving schemes for noise-resilient entangling gates with trapped ions, supporting an experimental partner in Innsbruck and a theory partner in Sofia. Combines analytical and numerical optimal control methods to identify and overcome imperfections limiting gate fidelities at finite temperature and without accurate calibration.

University of Exeter · Exeter · £21,805 pa

A 3.5-year PhD modelling nonlinear quantum optomechanical devices, focusing on suspended graphene resonators coupled to superconducting microwave cavities. The student develops analytical and numerical models of device dynamics, examines limitations like parasitic coupling and decoherence, and designs protocols for non-classical mechanical states, working with theorists and experimentalists.
