| Research Abstract |
Multi-zone planar traps have been developed and transporting ions has been succeeded. By placing small magnets on the back side of the trap substrate, a high magnetic field gradient that is sufficient for quantum state manipulation has been generated. Using the stimulated Raman adiabatic passage, a universal single-qubit gate based on the geometric phase factor has been realized. The decoherence-free two-partite entangled state has been generated successfully, and using the multi-level stimulated Raman adiabatic passage method, the four-partite Dicke state has been generated with high fidelity. We have succeeded in realizing a quantum rotor, in which three ultracold calcium ions arrange themselves in a triangular shape in a linear Paul trap, and demonstrated the Aharonov-Bohm effect with quantum tunneling.
