Quantum Technology Jobs in European Defence106 jobs

DefenceJobs tracks 22 companies working in quantum technology, and the range of what they build is broad. Quandela (photonic quantum computing, Massy) and IQM (superconducting quantum processors, Espoo) are building quantum computers through fundamentally different hardware approaches. Nu Quantum (quantum photonics, Cambridge) and KETS Quantum Security (quantum key distribution, Bristol) focus on the communications layer, where quantum physics enables encryption that is theoretically unbreakable by conventional or quantum computers. Aquark Technologies (cold atom sensors, Fareham) works on quantum sensing for navigation and detection. QuSide (quantum random number generators, Barcelona) and CryptoNext Security (post-quantum cryptography, Paris) build products that protect existing systems against the threat that future quantum computers pose to current encryption standards.

Candidates exploring this sector should expect a heavier emphasis on academic credentials than in most defence tech hiring. Roles at quantum hardware companies like IQM and Quandela typically require graduate-level physics or engineering, with experimental lab experience often valued as highly as industry experience. Software roles do exist, particularly at companies like CryptoNext Security, where the work involves implementing cryptographic algorithms rather than operating cryogenic equipment. Clearance requirements are generally lighter than in more established defence sectors, because much of the quantum work is still at the research and pre-production stage.
