Mid-senior Quantum Experimentalist

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, and we are growing fast after securing 30 million USD of funding in 2022 to develop our unique technology. Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!

Be part of the adventure of our ambitious startup trying to reduce tremendously the hardware needed for useful fault-tolerant quantum computing!

As a senior / staff quantum experimentalist at Alice & Bob, you will be at the frontline of our cutting-edge cat-qubit processors. In essence, your role will be to drive improvements and innovations of our processors to keep pushing the state-of-the-art with cat qubits. You will be in charge of measuring, characterizing, and optimizing our quantum circuits and gates using state-of-the-art techniques. You'll play a pivotal role in improving our experimental setup and tools, driving advancements that enhance the performance of our cat-qubit processors. You will have the opportunity to work together with other top-level teams internally and represent scientific research of the company externally. Your work will directly contribute to define the experimental roadmap of the company.

Responsibilities
