Query: Quantum optical gyroscope   Gyroscope for rotation sensing plays a key role in inertial navigation
systems. Developing more precise gyroscopes than the conventional ones bounded
by classical shot-noise limit by using quantum resources has attracted much
attention. However, the existing quantum gyroscope schemes suffer severe
deterioration under the influence of decoherence, which is called the no-go
theorem of noisy metrology. Here, by using two quantized optical fields as
quantum probe, we propose a quantum-optical-gyroscope scheme breaking through
the constraint of the no-go theorem. Our exact analysis on the non-Markovian
noise reveals that the ideal sensitivity achieving the super-Heisenberg limit
is asymptotically recoverable when each optical field forms a bound state with
its environment. The result provides a guideline in realizing high-precision
rotation sensing in realistic noisy environments.
