Company mission
To accelerate the practical application of quantum computing.
Role
Who you are
- A background in quantum computing is not necessarily required, though in this case a successful candidate will have evidence of the ability to design and implement advanced algorithms for optimization and/or constraint satisfaction
- Expertise in one or more of:
- Quantum information and/or computation theory
- Theory and implementation of classical algorithms for optimization or constraint satisfaction
- Quantum algorithm design and implementation
- Mathematical analysis of algorithms
- Proven track record of working independently on research projects
- Deep expertise and an excellent publication track-record in relevant discipline
- Excellent written and verbal communication skills and the ability to disseminate research results to technical and non-technical audiences
- Flexibility to work across different aspects of quantum algorithms, and to work on other tasks required to support the growth and success of the company
- An interest in near-term quantum computing
Desirable
- 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
What the job involves
- We are looking to hire a Quantum Algorithms Scientist to join our team
- The ideal candidate will have experience in the theory and/or implementation of optimization algorithms for gate-model quantum computers, or in classical optimization or constraint satisfaction algorithms; or otherwise strong evidence of potential to contribute to these areas
- Their work will initially focus on these topics, though they will have the opportunity to grow a portfolio of research activity across the breadth of Phasecraft’s interests
- 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/or 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
- Work with stakeholders on collaborations applying quantum computing to optimization problems
- Other activities as required to support the growth and success of Phasecraft
Our take
We are bumping up against the ceiling of Moore’s law. As classical computing chips reach physical limits, the exponential increases in computational power that we have been enjoying for decades will soon be a thing of the past. Quantum computing could be the answer.
Phasecraft is developing algorithms and software that push today’s quantum hardware beyond experimental demonstrations and towards useful applications. Its work could accelerate the application of quantum computers by years, if not decades.
The startup is now focused on pushing its technology as far as possible through collaboration with the leading quantum researchers around the world. Recently the company unveiled its quantum systems to be 1,000X faster than classical computers, this paired with some serious funding, put the company in a very good position for growth within the evolving market.
