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 in the UK and opened an office in Washington DC in 2024, led by Steve Flammia. In 2023 we completed a $17m 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, Rigetti, and QuEra – 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 delighted to launch our 2025 Quantum Algorithms Internship programme. As a Quantum Algorithms Intern you will have the opportunity to join the Phasecraft team for a few (typically 3) months. Not only will you work on a technical research project focusing on the design, implementation or analysis of quantum algorithms and related techniques in near-term quantum computing, but you will also have the chance to experience life in a young and vibrant startup that is constantly pushing the boundaries of our knowledge of quantum computing. Past projects have ranged from theoretical work on the underpinning mathematics of quantum algorithms to writing code for real or simulated quantum hardware.
Our recent internship programmes have proven to be meaningful and successful. In 2022 we hired our first permanent staff member who had previously participated in our Internship programme and we have several ongoing collaborations with former interns. Some of the work undertaken during internships has led to high-quality publications (such asOptimizing fermionic encodings for both Hamiltonian and hardwareandExtracting the spin excitation spectrum of a fermionic system using a quantum processor). Our team has enjoyed working on challenging projects with talented interns with diverse academic backgrounds including Quantum Information Theory, Materials Science, Physics and Computer Science.
The internship is a paid position with a competitive salary. Interns are based with the Phasecraft team in our offices in Bristol and London in the UK, and Washington DC in the US. Internships usually take place over the summer months, though dates can be flexible.
Requirements
As a Quantum Algorithms Intern, we expect you to have a demonstrable and keen interest in quantum computing and quantum information. You should have taken a taught course on quantum computing or a closely related topic, or have research experience in the area. Most previous interns have been undertaking a PhD on the theory of quantum computing or in a relevant area such as Materials Science or Computer Science, but we will also consider outstanding undergraduate students and those who are not currently enrolled in an academic programme.
To apply, please click on "Apply for this job" below and include your CV, details of two referees, a covering letter and academic transcript.
Within your covering letter, please indicate which of the following project areas you are interested in. Please note the requirements for each, and you are welcome to choose more than one project theme:
- Quantum algorithms [must be working towards, or have completed, a PhD in quantum computing or a related area]
- Software implementation / engineering [must have experience with coding]
- Materials science [must be working towards, or have completed, a PhD in chemistry, materials science, condensed-matter physics, or a closely related area]
The closing date is 9th March 2025.
In the UK we welcome international applicants who are eligible for a UK Government Authorised Exchange visa.
