Principal 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!

The Principal Research Scientist - Quantum Error Correction is a pivotal role in our organization, leading the design and development of our fault-tolerant architecture. Your work will directly contribute to shape the hardware roadmap of Alice&Bob. You will play a key role in bridging the gap between theoretical quantum error correction schemes and their real-world applications, thereby significantly impacting the future trajectory of our company's technological advancements.
