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, 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 algorithms for gate-model quantum computers or related topics in quantum computing theory, quantum information theory or related areas of quantum theory*.* Their work will contribute to Phasecraft's goal of developing quantum algorithms for near-term quantum computers, and may encompass topics such as algorithm optimization and design, quantum codes, resource analysis, error mitigation, and hardware benchmarking. 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 on near-term quantum computing algorithms, applications and/or enabling theoretical technologies. * 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 quantum information and/or computation theory. * PhD (or soon to receive one) in quantum information, quantum computation theory, theoretical computer science, theoretical physics, or closely related field. * Ability to work independently on research projects and to work in a team. * Strong publication track-record in relevant discipline. * Flexibility to work across different aspects of quantum software and underpinning theory. * Flexibility to work on other tasks required to support the growth and success of the company. *Desirable criteria:* * An interest in near-term quantum computing. * Either experience of implementing algorithms on quantum hardware and/or in classical emulation; or strong theoretical/mathematical research track-record with an interest in applying this to quantum computing; or software development skills and experience. * Enthusiasm for learning and novel research. * Excellent communication skills.
