Dissipative adiabatic measurements: Beating the quantum Cramér-Rao bound
Dissipative adiabatic measurements: Beating the quantum Cramér-Rao bound
It is challenged only recently that the precision attainable in any measurement of a physical parameter is fundamentally limited by the quantum Cram\'{e}r-Rao Bound (QCRB). Here, targeting at measuring parameters in strongly dissipative systems, we propose an innovative measurement scheme called {\it dissipative adiabatic measurement} and theoretically show that it …
