Quantinuum · London

Develops novel quantum algorithms in computational topology and geometry, characterising resource requirements and noise-robustness, then implementing and optimising them on Quantinuum's quantum hardware using error mitigation and error correction. Works across the full quantum computing stack with hardware, QEC and software teams, and with academic and industry partners on quantum topological data analysis use cases.

Quantinuum · London · £2,500 pm

Interns join the UK Quantum Error Correction team to work on an active research project spanning architectural design, analysis and implementation of the QEC stack, from tensor networks and ZX calculus to fault-tolerant magic state gadgets and trapped-ion demonstrations. Based in London or Cambridge, the role sits in a research-focused group with close ties to hardware and software engineers, aiming at a publication and/or software libraries.

University of Exeter · Exeter · £21,805 pa

A computational PhD project unifying open quantum spin dynamics simulations with deep-learning protein generation to build an in silico directed evolution pipeline. The candidate will design biological qubits that transduce spin-dependent events into functional effector signals, using tools such as ColabDesign, ProteinMPNN, molecular dynamics and DFT, with co-supervision from NPL and collaboration with Orion Life.

Universal Quantum · Haywards Heath
