Event Details & Abstract: 

The recent observation of entanglement between a mechanical oscillator and the electromagnetic field by Palomaki et al. ultimately witnesses the dawn of the quantum age in optomechanics. In this talk I will show that this pulsed protocol can be extended to the time continuous regime, and that optomechanical entanglement can serve as a resource for remote preparation of arbitrary quantum states, or quantum steering, through time continuous teleportation. The experimental requirement is a strong optomechanical cooperativity (for linearized coupling), the same as for ground state cooling and observation of back action noise. On a more general perspective, light-matter entanglement provides a universal resource for quantum networks interfacing mechanical systems with other quantum systems, such as atoms or superconducting qubits, exhibiting sufficiently strong coupling to the electromagnetic field.
