Theory 62/Quantum Sensing
Dynamic Range Is a Decoherence Ratio
The claim
The dynamic range of a quantum sensor is set by the ratio of decoherence rate to drive strength, so stronger driving widens range at the cost of coherence.
01The mechanism
A sensor saturates when the signal drives it faster than it can relax; the ratio sets the upper end of the linear range.
02Predictions
- P1Range should track the ratio.
- P2Drive strength alone should mispredict.
03Refutation
Range tracking drive strength would remove the decoherence term.
