Other teams, like Q-CTRL, an Australian quantum technology company, are focusing on using software to build robust systems from noisy quantum sensors. Quantum navigation involves taking those delicate sensors, honed in the placid conditions of a laboratory, and putting them in vehicles that make sharp turns, bounce with turbulence, and bob with waves, all of which interferes with the sensors’ functioning. Even the vehicles themselves present problems for magnetometers, especially “the fact that the…
