Query: Dynamical Gaussian state transfer with quantum error correcting
  architecture   Transferring a quantum state of a light field to a memory is of particular
importance. However, this transfer is usually hampered because the memory
system is subjected to some noise and this can limit the performance of the
state transfer to a great extent. In this paper, we consider the transfer of a
Gaussian state of light to a linear medium memory such as an opto-mechanical
oscillator and propose a dynamical feedback controller that suppresses the
noise in the memory system. To protect an unknown state, the feedback scheme
employs the specific configuration of the quantum error correction; that is, a
three-mode Gaussian state having appropriate syndromes is taken as the input.
Correspondingly, the memory consists of three independent linear systems. The
syndrome errors are estimated continuously in time through the measurement of
the output field, and the results are then fed back to control the system.
Because the input is Gaussian and the systems are all linear, it is possible to
formulate the problem using the framework of the celebrated classical Kalman
filtering and linear quadratic Gaussian control. A numerical simulation
demonstrates the effectiveness of the control scheme.
