| Abstract | |
Quantum teleportation, the faithful transfer of an unknown input state onto a remote quantum system(1), is a key component in long-distance quantum communication protocols(2) and distributed quantum computing(3,4). At the same time, high-frequency nano-optomechanical systems(5) hold great promise as nodes in a future quantum network(6), operating on-chip at low-loss optical telecom wavelengths with long mechanical lifetimes. Recent demonstrations include entanglement between two resonators(7), a quantum memory(8) and microwave-to-optics transduction(9-11). Despite these successes, quantum teleportation of an optical input state onto a long-lived optomechanical memory is an outstanding challenge. Here we demonstrate quantum teleportation of a polarization-encoded optical input state onto the joint state of a pair of nanomechanical resonators. Our protocol also allows to store and retrieve an arbitrary qubit state onto a dual-rail encoded optomechanical quantum memory. This work demonstrates the full functionality of a single quantum repeater node and presents a key milestone towards applications of optomechanical systems as quantum network nodes. (AU) | |
