Preparation of Entangled States Based on Strong Coupling Between...

A scheme of strong coupling between the double electron spins and the quantized nano-mechanical harmonic.oscillator is proposed based on the diamond nitrogen vacancy (NV)color center. A two-dimensional entangled state of.two qubits is prepared by using the dissipative process。[the nano-mechanical harmonic oscillator.丁he numerical.simulation results show that, all the systems with different initial states can evolve to the target states with a high.fidelity and a high entanglement.丁his scheme
