We are excited to partner with Q-Block Computing to attract top talent for Principal Quantum Scientist.

This job posting is a new position within our organization.

About Q-Block Computing: Q-Block Computing is a Canadian quantum technology company on a mission to decode Nature's foundational model — to build instruments precise enough to orchestrate atoms and photons, and to ask whether a quantum system can, in principle, capture Nature's computational power. We are a home for the curious mind and unconventional thinking, a sanctuary for avant-garde science and blue-sky research on time horizons longer than today's academic institutions.

Some of the most important questions require decades to answer, and patience is not passivity but strategic discipline.

Q-Block Computing Research is the fundamental science division of the company. It is where we pursue the deepest questions — the computational power of Nature, the structure of quantum field theories, the link between entanglement and spacetime, and the foundations of quantum metrology. The research we do here shapes what becomes possible across every other part of the company; the rest of the company exists, in part, to make this research possible.

About this role: The Principal Quantum Scientist will define the scientific identity and long-range research program of Q-Block Computing Research — setting the direction of frontier experimental and theoretical work in quantum information science, AMO physics, quantum metrology, and related foundational domains.

This is a role for a scientist of the highest caliber: someone who has made original, recognized contributions to quantum physics, who has the range and vision to define a multi-year research agenda, and who finds more meaning in the pursuit of deep scientific truth than in the routine execution of established programs. We are building toward questions such as understanding the computational power of Nature, the structure of strongly correlated quantum matter, the physics of entanglement at scale, the ultimate limits of quantum measurement, and we need the kind of mind that finds those questions genuinely irresistible.

The candidate we are looking for has already demonstrated the ability to set and drive their own research agenda at the highest level of the field. They are capable of choosing problems that matter, building the tools to attack them, and carrying a program from concept to result with very little external scaffolding. What we offer is the environment that kind of scientist needs to do their best work: deep engineering infrastructure, institutional conviction behind long-horizon science, and the freedom to ask questions that are larger than a grant cycle.

The focus is on building and understanding, without the administrative and performative burdens that have grown up around much of contemporary research, and with commercial programs deliberately structured to fund and amplify fundamental work rather than crowd it out.

How Q-Block Computing Research differs from an academic institution: Q-Block Computing Research is built for scientists who want to pursue…
