Join Nu Quantum - Shaping the Future of Technology

Nu Quantum is at the forefront of quantum computing and advanced technology, driven by innovation, diversity, and a commitment to excellence. We're creating an environment where brilliant minds from all backgrounds collaborate to push the boundaries of what's possible.

Founded to commercialise research generated over the last decade at the Cavendish Laboratory, Nu Quantum is on a mission to shape the future of quantum information systems.

We're working on exciting technology that will improve the utility and accelerate the time-to-market of quantum computing systems. We integrate novel quantum photonic technology to form an efficient and scalable quantum networking infrastructure in partnership with world-leading companies and academic groups.

About The Role

We're looking for a skilled and experienced 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'll 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'll 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'll 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're excited by the challenge of connecting the quantum world — and want to work on technology that's defining the field — we'd love to hear from you.

Responsibilities

• Design and execute remote‑entanglement experiments to benchmark and advance ion‑trapping devices with Nu Quantum's integrated micro‑cavity technology
• Mentor and support AMO Physicists, helping them grow technical depth, independence, and problem‑solving capability
• Develop, 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
• Keep project teams and Project Management Office aligned through clear, timely communication of results, progress, and priorities across interdependent, fast‑moving workstreams
• Establish and uphold best practices in laboratory safety, documentation, and system reliability
• Contribute to technical strategy, identifying opportunities to improve experimental design, automation, and scalability

Requirements

• Experience in experimental AMO physics, preferably in ion‑trapping, or a related discipline
• Hands‑on experience with quantum control of qubits with optical fields, gate optimisation and benchmarking
• Deep understanding of qubit control, atomic physics and atom‑phonon interactions
• Hands‑on experience designing and integrating optical, electronic, and UHV systems
• Expertise in at least two of these areas: laser locking, system automation, and real‑time control (e.g. ARTIQ)
• A system‑level mindset — comfortable defining requirements and connecting hardware, software, and control layers
• Excellent collaboration and communication skills, with the confidence to take initiative, make independent technical decisions, and drive solutions forward
• Willingness to mentor others and a readiness to take ownership of technical direction as the team grows

Bonus points for

• Past experience providing technical leadership within a collaborative team to deliver complex projects in a fast‑paced environment
• Contributions to project proposals, technical roadmaps or long‑term project strategy
• A proven track record in scientific communication (papers, talks, conferences)
• Experience with cavity QED

Benefits

At Nu Quantum, we celebrate diversity and are committed to creating an inclusive workplace where people of all identities, orientations, backgrounds, and experiences are empowered. We value diverse perspectives as a source of creativity and innovation and encourage applications from all backgrounds, including those from underrepresented and marginalised communities. Joining Nu Quantum means joining a team where you can grow professionally and be part of an inspiring mission to shape the future of technology.
