报告摘要：

In this talk, I report an innovative measurement scheme called dissipative adiabatic measurement. Unlike projective measurements, the reported measurement scheme, though consuming more time, does not collapse the measured state and, more importantly, yields the expectation value of an observable as its measurement outcome. Using these exotic features, I theoretically show that the precision reachable in this scheme goes beyond the well-known ultimate precision allowed by quantum mechanics, i.e., the quantum Cramer-Rao bound. As such, the measurement scheme may have potential applications in quantum sensing.
