Strong Coupling between a Topological Qubit and a Nanomechanical Resonator
arXiv:1301.4987 · doi:10.1103/PhysRevA.87.032339
Abstract
We describe a scheme that enables a strong coherent coupling between a topological qubit and the quantized motion of a magnetized nanomechanical resonator. This coupling is achieved by attaching an array of magnetic tips to a namomechanical resonator under a quantum phase controller which coherently controls the energy gap of a topological qubit. Combined with single-qubit rotations the strong coupling enables arbitrary unitary transformations on the hybrid system of topological and mechanical qubits and may pave the way for the quantum information transfer between topological and optical qubits. Numerical simulations show that quantum state transfer and entanglement distributing between the topological and mechanical qubits may be accomplished with high fidelity.
