Quantum computational displacement sensing with trained parameterized circuits achieves up to 15 percentage points higher binary classification accuracy than conventional quantum sensing plus classical postprocessing on superconducting hardware.
The compass-state sensing protocol relies on the fact that a compass state that is displaced byD(α) is quasiorthogonal to the undisplaced compass state on a scale set by 1/|α|[31]
