Quantum computing with neutral atoms in an optical lattice

We present a proposal for quantum information processing with neutral atoms trapped in optical lattices as qubits. initialization and coherent control of single qubits can be achieved with standard laser cooling and spectrosc opic techniques. We consider entangling two-qubit logic yates based on opti cally induced dipole-dipole interactions, calculating a figure-of-merit for various protocols. Massive parallelism intrinsic to the lattice geometry m akes this an intriguing system for scalable, fault-tolerant quantum computa tion.
