Research Scientist - Quantum Error Correction

Research – Theory /
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 are at the forefront of the quantum race, competing with tech giants such as Google or IBM. We are growing fast, securing 30 million USD of funding in 2022 to develop our unique technology. We are 80 and counting, between physicists, PhDs, engineers and experienced business professionals, all united in reaching our ambitious goal. If you are an explorer, craving to challenge yourself and make quantum computing come true, come and join us!

As a Research Scientist - Quantum Error Correction, your role will be to improve the design of Alice&Bob fault-tolerant architecture. You will work in close collaboration with the rest of the theory team and with the experimental teams in order to create superior fault-tolerant schemes adapted to the bosonic processors that Alice&Bob is building.

Your work will be at the inception of the Alice&Bob innovation cycle, as the architectures proposed by the Quantum Error Correction team are the starting point of the hardware design, implementation and characterisation cycle. As such, you will have a direct and strategic impact on the hardware roadmap and will see your theoretical work become an experimental reality.
