Phasecraft is the quantum algorithms company. We are building the mathematical foundations for quantum computing applications that solve real-world problems. Founded in 2019 by Toby Cubitt, Ashley Montanaro and John Morton, we are based in London and Bristol, UK. In 2023 we completed a £13m Series A funding round led by leading Silicon Valley deep tech VC, Playground Global.

Phasecraft’s unprecedented access to today’s best quantum computers – through partnerships with Google, IBM, QuEra and Rigetti – provides us with unique opportunities to develop foundational IP, inform the development of next-generation quantum hardware, and accelerate commercialisation of high-value breakthroughs.

We are looking to hire a Quantum Algorithms Scientist to join our team. The ideal candidate will have experience in the theory of optimization algorithms for gate-model quantum computers, or experience in the theory of quantum algorithms more generally and strong evidence of potential to contribute to this area. Their work will initially focus on this topic, though they will have the opportunity to grow a portfolio of research activity across the breadth of Phasecraft’s interests.

Job Description

• Undertake theoretical and/or applied research and/or software development for near-term quantum computing applications, with an initial focus on quantum algorithms and software for combinatorial optimization and constraint satisfaction problems.
• Help to author publications, presentations, patent applications and similar resulting from the research.
• Work collaboratively in a small team made up of full-time staff and affiliated PhD students.
• Other activities as required to support the growth and success of Phasecraft.

Requirements

Essential criteria:

• Expertise in one or more of:
  o quantum information and/or computation theory
  o theory and/or implementation of classical algorithms for optimization or constraint satisfaction
  o quantum algorithm design and/or implementation
  o mathematical analysis of algorithms
• Ability to work independently on research projects and to work in a team.
• Flexibility to work across different aspects of quantum software and underpinning theory.

Desirable criteria:

• PhD (or soon to receive one) in quantum information, quantum computation theory, theoretical computer science, or closely related field.
• Coding in quantum software development environments (e.g. Cirq, QuEST, Qiskit).
• Experience of implementing algorithms on quantum hardware.
• Strong publication track-record in relevant discipline.
• Software development skills.
• Enthusiasm for learning and novel research.
• Excellent communication skills.
