Quantum Sensor Network And Measuring Multple Functions With A Quantum Sensor

Published Patent Application Number: 2024/0185109

Problem

Sequential protocols divide the problem into n time intervals, where each time interval is optimized to estimate a single function from the set {f’1, f’2, ..., f’n}, which may consist of linear combinations of the original set { f1, . . . , fn}.

Previous protocols achieved higher uncertainty for the same amount of time, or equivalently, achieved the same uncertainty but in a longer time.

Invention

It is an entanglement-based protocol to measure simultaneously multiple analytic functions of a set of parameters coupled to qubit sensors. 

Potential Commercial Applications

This protocol can be used to measure properties of spatially varying fields such as magnetic fields, electric fields, gravitational fields, and temperature, with applications in fields such as chemistry, medicine, biology, materials science, physics, geodesy, and geophysics.
