About the team
The Quantum Computing Research team is dedicated to developing innovative methods to get the best possible performance from contemporary and next generation quantum computers. We push toward quantum advantage by developing cutting-edge applications, employing AI, control theory, and physics principles to optimize and automate critical parts of the quantum computing stack. We conduct pioneering research looking toward the near future, including quantum error correction and the integration of quantum computers with high performance computing and data centers.
About the role
We are seeking a new Research Scientist / Senior Research Scientist to focus on error suppression in quantum circuits. You will work within a team of researchers dedicated to developing innovative new methods to get the best possible performance of near-term quantum computing hardware. A major focus of our research team is robust execution of quantum algorithms on real hardware; for example, by hardware-aware compilation, embedding dynamical decoupling, and pulse-level and gate-level quantum control techniques. In this role, you will collaborate regularly with engineering and project teams to implement your ideas into our software products, and to apply your insights to a variety of quantum computing hardware platforms, and to implementations of specific quantum algorithms and applications. This position offers the opportunity to work at the forefront of quantum computing, driving innovation, and delivering impactful solutions.
As a Research Scientist, you’ll be responsible for developing solutions for quantum technologies and deploying them in the Q-CTRL product suite.
What you'll be doing:
- Develop efficient and reliable methods and tools that solve challenges facing real quantum computers.
- Stay informed about the latest advances in quantum computing and quantum control, and leverage this knowledge to implement and refine cutting-edge methodologies.
- Utilize methods from a range of fields, including control theory, optimization, machine learning, computer science, and data analysis.
- Create code for optimizing quantum algorithms, near-term quantum applications, and quantum error correction schemes.
- Collaborate with engineering teams to translate your ideas into production-quality software.
- Engage with users to gather feedback and enhance our products.
- Explain and present your work in clear and accessible language. Incorporate feedback and foster effective collaboration with colleagues.
- Write articles for publication in peer-reviewed journals, attend and present your work at conferences, and collaborate with other industrial and academic research groups.
- Use open-source scientific computing packages like Qiskit, NumPy, Networkx, Scipy, Scikit-learn, and PyTorch to build high-quality research code to develop, demonstrate, and test new algorithms and methods.
- Other duties within the Employee's skills and experience, or with reasonable training.
Ideally you'll have:
- An advanced degree in Physics, Engineering, Mathematics, Computer Science, or a related discipline. A PhD is preferred, but we will also consider exceptional individuals with previous industry experience.
- Expertise in quantum computing. Specifically, for this role we would like to see a background and interest in quantum control theory, and/or error suppression in quantum systems or circuits.
- A track record of conducting impactful research, demonstrated through publications and/or presentations in well-regarded journals and/or conferences.
- Experience in developing software for scientific experiments using one of the commonly-used languages such as Python, Julia, Matlab, or Mathematica (our team primarily uses Python).
It would be fantastic if you have these skills/experience but not essential:
- Experience with high-performance languages such as Rust, C++, or Julia.
- Experience with GPUs, TPUs, and other forms of hardware-accelerated computing.
- A strong background in relevant methods from fields such as control theory, optimization, machine learning, or data analysis.
- Familiarity with error suppression techniques used in quantum computing, such as dynamical decoupling, readout mitigation, zero-noise extrapolation, Pauli twirling, or pulse-level optimization.
- Familiarity with executing circuits in Qiskit.
- Exceptional scientific communication skills, evidenced by a track-record of teaching, scientific outreach, writing, producing elegant figures and visualizations, and/or speaking in front of both general and expert audiences.
We take a multidisciplinary approach to quantum computing research, bringing together experts from diverse fields. We particularly value versatile and self-motivated problem solvers. If you are passionate about making quantum computers useful, we strongly encourage you to apply, even if you do not meet all of the requirements listed above.
Salary
The base salary for this position is targeted between $140,000 - $187,500 and will ultimately be determined by specific job-related skills, experience, level, location and other contributing factors. Depending on the position offered, this role may be eligible for annual discretionary bonuses, equity and other forms of compensation outside of the targeted range.
