| Research Abstract |
After through study of existing proposals of qubits, we have chosen neutral atom as a candidate for a potentially scalable qubit, which is controllable and robust against decoherence. We proposed a scheme to overcome the lack of selective controllability, which is a difficulty associated with this system. We have shown that a system of neutral atoms trapped by near-field optical traps and optical lattices satisfies all the requirements for a scalable quantum computer within currently available technology.
