Research Scientist, Quantum Algorithms - 346 in London

We are seeking a Research Scientist for our quantum algorithms team in London or Cambridge, UK. Our team leads the development, implementation, simulation, and application of quantum algorithms for computational problems of both scientific and practical relevance.

Responsibilities

• Contribute to the design of novel quantum algorithms and to the development of techniques aimed at reducing algorithmic overheads for execution on Quantinuum’s hardware.
• Estimate end-to-end resource requirements under realistic hardware constraints.
• Develop new techniques and quantum computational models aimed at reducing circuit depth and making quantum circuits shallower, and co-design algorithms with our hardware, including early fault-tolerant protocols and error correction or detection primitives.
• Publish and present results; work in a collaborative environment and engage with academic and industry partners.

Requirements

• PhD in a relevant field (physics, mathematics, computer science, etc.)
• Research experience in quantum algorithms, with expertise in at least one of: quantum algorithm design and optimization, realistic noise models of quantum hardware, quantum error correction, or (partially) fault-tolerant protocols.

What we value

• Demonstrated research track record via publications in a relevant field.
• Deep knowledge of quantum computing and quantum algorithm design.
• Hands-on experience with implementing quantum algorithms on simulators or hardware.
• Excellent written and oral communication skills.
• Programming skills in a high-level language such as Python and relevant tools such as pytket, Qiskit, etc.

What is in it for you?

Working alongside a highly talented team, with leading names in the quantum computing industry. We offer a highly competitive package, equity, 28 days of paid holiday (in addition to public holidays), a workplace pension, a positive approach to flexible working and enhanced parental and adoption benefits.
