Q-CTRL
Senior Research Scientist, Silicon Qubits
Q-CTRL, Los Angeles, California, United States, 90079
About us
Founded in 2017, Q-CTRL has grown to become the global leader in quantum. We’re using control to solve the hardest problems facing quantum technology, improving hardware performance and accelerating pathways to useful quantum computers and other technologies. As a product-led company, we bring together diverse teams such as product, design, engineering and research to help achieve our mission of making quantum technology useful. Join us to help shape the quantum future.
As one of the fastest growing companies in the quantum sector, we’ve had a number of key milestones:
We announced an industry-first partnership with IBM Quantum Services, natively integrating our performance management software with all IBM quantum computers. Building off of this relationship, we started offering two services via IBM’s new Qiskit Functions Catalog as an inaugural partner.
We designed and moved our Global HQ offices and lab space into the first purpose-built (and award winning) commercial and research facility for a quantum technology company in Australia.
We continued to deliver real world outcomes across the quantum sectors, with our work with Australian Defence on software-ruggedized quantum sensing for navigation without GPS, as featured in the New York Times.
We announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital.
We grew our global presence to include Los Angeles, Berlin, and Oxford - as well as the recently announced office in San Francisco.
From educating the workforce on how quantum computing works, to building the next generation of quantum sensors, to delivering massive performance gains for end-users, it all starts with hiring the right talent. If you want to help us build the Quantum future, read on.
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. In this role, you will work in a team of quantum scientists to develop software solutions for calibration and optimization of quantum dot devices. You will focus on building robust routines for coarse tuning, calibrating high-fidelity single and two-qubit gates, optimizing the full processor at scale, and maintaining peak performance in real time. You will collaborate regularly with other cross-functional teams such as research, product and engineering, to apply your insights to a variety of quantum computing challenges and turn your ideas into usable software tools. This position offers the opportunity to work at the forefront of quantum computing, driving innovation, and delivering impactful solutions. What you'll be doing:
Perform cryogenic measurements and characterization of quantum dot-based qubits. Invent, implement and test novel control protocols for all the required bring-up steps starting from coarse tuning to optimizing two-qubit gates. Develop scalable protocols for processor-wide optimization (e.g. cross-talk mitigation, leakage reduction, defects mitigation), and real-time retuning. Collaborate with your colleagues in the engineering and product teams to translate ideas and research outcomes into production-level software. Explain, document and present research solutions in accessible language. Ideally you'll have:
An advanced degree in Physics, Engineering, or a closely related discipline. A PhD is preferred, but we also consider exceptional candidates with previous industry experience. 2 years of experience conducting research in a relevant field. Previous experience in tune-up and characterization of quantum dots. Expertise in numerical techniques, statistical learning, and optimization algorithms. A good grasp of software development best practices, and experience in developing software modules for qubit measurement and control (Python, C++, Rust). Salary
The base salary for this position is targeted between $140K - $192K 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. Why Q-CTRL?
We offer a range of benefits, including flexibility, attractive salary, equity, cash bonus, resources, parental support, diversity, unique culture, meaningful values, personal development, and the opportunity to make a dent in the quantum future. We are an equal opportunity employer and actively support initiatives like the ‘Global Women in Quantum’ program to help expand the quantum workforce. Q-CTRL aims to bring together cross-functional teams from many different backgrounds to help achieve our goals - we strongly encourage you to apply even if you do not meet all of the requirements mentioned in the job posting. Qualified applications with arrest or conviction records will be considered for employment in accordance with the Los Angeles County Fair Chance Ordinance for Employers and the California Fair Chance Act.
