Magnetic-Field Sensing with a Transmon Qubit

Caption

Probability distributions (shown in red and blue for the two algorithms used in the work) narrow down in consecutive steps of the algorithms, leading to the precise identification of the magnetic-flux value. The green curve is the standard-quantum-limit distribution and the background is the interference pattern characteristic of the device.
