Optimal protocols for simultaneous measurement of multiple analytic functions with quantum sensor networks
ORAL
Abstract
We expand on previous work for measuring analytic functions of input parameters of quantum sensor networks with qubit sensors. We consider the optimal bound with respect to different figures of merit for simultaneous measurement of multiple such analytic functions and propose protocols to achieve these bounds and thus Heisenberg scaling in the mean square error. We discuss conditions on the analytic functions where the possible speed-up over classical or sequential protocols is greatest and consider potential applications.
