Multiparameter squeezing for optimal quantum enhancements in sensor networks
Quantum metrology often deals with the simultaneous estimation of multiple parameters, but the optimal use of squeezing is not yet fully understood in this case. Here, the authors define a generalised squeezing matrix that quantifies the quantum gain in a moment-based multiparameter estimation proto...
