Quantum Logic Scientist
Sparrow Quantum
Build Fault-Tolerant Quantum Computing from First Principles
Sparrow Quantum is looking for a Quantum Logic Scientist to strengthen our theory effort at the core of our photonic quantum computing roadmap. This role is for someone who wants to work hands-on with fault tolerant quantum logic, noise models, and error-correcting codes, while staying tightly connected to experimental reality.
You will work alongside theorists and experimentalists to design, analyze, and validate error correction strategies tailored to photonic platforms based on quantum emitters. The work feeds directly into product direction, scientific publications, and long-term architecture decisions.
This is a deep technical role in a fast-moving scale-up environment. You are expected to think rigorously, move quickly, and engage directly with real experimental constraints.
Responsibilities
Develop and analyze fault-tolerant quantum logic and error correction schemes tailored to photonic platforms
Perform circuit-level noise simulations and error modelling
Contribute to the design and evaluation of error correction codes and decoding strategies
Collaborate closely with experimentalists to align theory development with hardware constraints
Contribute to scientific publications, patents, and technical documentation
Participate in planning and execution of scientific and innovation projects
Represent Sparrow Quantum at scientific conferences and workshops when relevant
Who You Are
You always strive for excellence and want to deliver work that you’re proud of.
You’re looking for challenges, continuous improvement and opportunities to grow.
You are collaborative; high-ownership teams bring out the best in you.
Must-Have Qualifications
PhD in quantum error correction, fault-tolerant quantum computing, or closely related field
Demonstrated research output, including publications in quantum error correction or fault tolerance
Experience with theoretical development of fault-tolerant quantum logic
Interest in photonic quantum computing and working in a scale-up environment
Nice-to-Have Experience
Knowledge of graph states, linear optics quantum computing, or quantum algorithms
