AMO Physicist in Newtown

We are looking for an experimental Physicist to join us in building our quantum-network demonstrator - a cornerstone of Nu Quantum's mission to create scalable, high-performance quantum networks. In this role, you will work at the intersection of atomic physics, cavity QED, and quantum engineering, joining the AMO physics team and collaborating closely with our experts across electronics, optics, and mechanical design. You will play a key role in integrating Nu Quantum's proprietary qubit-photon interface and cavity microtechnology, helping us push toward state-of-the-art networking rates and fidelities. This is a highly cross-functional, hands-on role where creative problem-solving and system-level thinking are essential. You will have the opportunity to shape experimental design, drive technical innovation, and directly contribute to the long-term vision of making practical quantum networking a reality.

If you are excited by the challenge of connecting the quantum world - and want to work on technology that is defining the field - we would love to hear from you.

Responsibilities:

• Execute remote-entanglement experiments to benchmark and advance ion-trapping devices with Nu Quantum's integrated micro-cavity technology.
• Support other AMO Physicists, helping the team grow technical depth, independence, and problem-solving capability.
• Help maintain and troubleshoot complex laboratory systems - including laser setups, RF/DC electronics, control systems, and ultra-high-vacuum hardware.
• Collaborate across disciplines with Software, Optical, Mechanical, and Electrical Engineers, as well as with theory and simulation teams, to deliver integrated experimental systems.
• Participate in project teams through clear, timely communication of results, progress, and priorities across interdependent, fast-moving workstreams.
• Uphold best practices in laboratory safety, documentation, and system reliability.
• Participate in the development of technical strategy, identifying opportunities to improve experimental design, automation, and scalability.

Qualifications:

• Experience in experimental AMO physics, preferably in ion-trapping, or a related discipline.
• Understanding of qubit control, atomic physics, atom-phonon interactions, gate optimisation or benchmarking.
• Experience working with optical, electronic, and UHV systems.
• Understanding of laser locking, system automation, or real-time control (e.g. ARTIQ).
• A system-level mindset - comfortable connecting hardware, software, and control layers.
• Collaboration and communication skills, with the confidence to take initiative, make independent technical decisions, and drive solutions forward.
• Past experience within a collaborative team delivering complex projects in a fast-paced environment.
• Contributions to project proposals, technical roadmaps or long-term projects.
• Experience of scientific communication (papers, talks, conferences).
• Experience with cavity QED.

Benefits:

• Flexible working options.
• Group DIS cover (4 x salary).
• 1 month paid Sabbatical after 4 years of service.
• Generous Employee Referral Scheme.
• Private Medical and Dental Cover (With Vitality and Bupa).
• On-site gym membership.
• Cycle scheme.
• Refreshments, including fruit and beverages, are available in the office.
• 28 days annual leave, including a 3-day company shutdown period + UK Public Holidays.
• Option to purchase up to 5 days holiday per year.
• Enhanced paid family leave policies.
• Access to the Cambridge Botanical Garden.
