In this chapter, we propose a protocol for coherently transferring non-Gaussian quantum states from the optical field to a mechanical oscillator, which does not require a no

Gabriella D‘Agostino,Vincenzo Materay adopting an optimal time-dependent homodyne detection method, in which the phase of the local oscillator varies in time, the conditional quantum state can be characterized below the Heisenberg limit, thereby achieving a quantum tomography. In the limiting case of no readout loss, such a scheme eva

This is motivated by the pioneering work of Vyatchanin et al. [., .], in which such a back-action-evading variational scheme is proposed to detect a force signal with known arrival time.

In this chapter, we provide a new but physically equivalent insight into the origin of such a limit: that is information loss due to a finite cavity bandwidth.
