Continuous optical-to-mechanical quantum state transfer in the unresolved sideband regime
Optical-to-mechanical quantum state transfer is an important capability for
future quantum networks, quantum communication, and distributed quantum
sensing. However, existing continuous state transfer protocols operate in the
resolved sideband regime, necessitating a high-quality optical cavity and a
high mechanical resonance frequency. Here, we propose a continuous protocol
that operates in the unresolved sideband regime. The protocol is based on
feedback cooling, can be implemented with current technology, and is able to
transfer non-Gaussian quantum states with high fidelity. Our protocol
significantly expands the kinds of optomechanical devices for which continuous
optical-to-mechanical state transfer is possible, paving the way towards
quantum technological applications and the preparation of macroscopic
superpositions to test the fundamentals of quantum science
