Job Description

The future is quantum. Oxford Ionics is a high-performance quantum computing company delivering world-leading innovations to create the most powerful, accurate and reliable quantum computers to solve the world's most important problems. Quantum Computing offers a radically new way of building computers that harnesses the power of quantum physics to outperform conventional supercomputers exponentially. Using our unique trapped-ion technology, we are at the forefront of the race to unleash the real potential of quantum computing.

What to expect

We are building quantum computers based on trapped-ions. We leverage laser-free quantum control methods to create fully integrated quantum processors that can be made in silicon foundries. We see quantum computing as fundamentally a game of errors, and we build our systems to achieve ultra-low gate errors at scale. Our goal is to create a quantum computer which is helpful in the NISQ regime and then take advantage of the ultra-low gate errors to create fault-tolerant machines with low QEC overhead.

What you'll be responsible for

As a Quantum Architect, you will guide the design of the world's first truly practical quantum computers. You will work closely with our Quantum Hardware team and work to identify control solutions to improve the performance of our quantum computing systems. Together with the rest of the Quantum Architecture team, you will develop techniques for scaling today's quantum processors without sacrificing performance.

You would be responsible for developing numerical simulations of quantum dynamics (e.g. quantum gates, ion cooling, measurements) and creating and evaluating novel control protocols for trapped-ion control (e.g. noise-resistant pulse sequences). Furthermore, you will work on developing and analysing large-scale quantum system architectures and Analysing system-level choices and trade-offs.


You will need extensive expertise and research experience in the field of quantum information and computing. Regardless of whether your background is experimental or theoretical, it is essential that you have practical experience working with real-world hardware (e.g., theoretical modelling for an experimental project, benchmarking simulations against cloud-based quantum computer backends, etc.). Additionally, you should have comprehensive experience in low-level quantum system simulations, such as pulse-level simulation of quantum gates, Hamiltonian simulations, and dissipative protocols.

You may be a great fit if:

  • You have hands-on experience with quantum computing hardware - your expertise could be ions, atoms, photons, spins, dots or defects.
  • You have hands-on experience with quantum system simulations – either an experienced user of one of the quantum computing SDKs or maybe you’ve worked on an open-source quantum control package. Perhaps you have simulated quantum systems at a circuit level or with a master equation.
  • You understand the effect of noise on quantum systems – You may have simulated the noise threshold of a QEC code, Or maybe you had to simulate the effect of time-varying noise on your qubit. If you have experience in simulating noise and are motivated to fight it until the fault-tolerance threshold and beyond.


Oxford Ionics is at the cutting edge of quantum innovation. We need people like you with the necessary skills, vision and capability. In return, we'll recognise your engagement and excellence with a range of benefits. You'll find opportunities to further your career with a world-class team, business stock options, unlimited annual leave, flexible working hours with either hybrid or onsite working, private medical insurance for you and your family and much more.

Oxford Ionics is committed to equal opportunity for all.
