Expert Optimal Control Scientist

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.

The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈‍⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!

 

We're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!

Control is one of the decisive levers for how well this platform performs. The way a qubit is driven, stabilized, and read out determines how close the hardware gets to its theoretical limits. That is where this role sits.

 

As an Expert Optimal Control Scientist, you will design and optimize the control strategies that maximize gate fidelity, state preparation, and measurement on the cat-qubit platform — operating point selection, pulse shaping, feedback stabilization, and quantum error correction optimization, among others.

 

You'll report to the Team Lead, Control, and work closely with Chip Design, Performance Optimization, Calibration, and QEC to turn control-theoretic methods into measurable platform improvements — from simulation to deployment and iteration on real cat-qubit chips.
