One-way quantum computing with ultracod atoms in optical lattices

In the 'one-way' model of quantum computation, one only needs to make a series of measurements on qubits in highly entangled states, known as cluster or graph states. These states can be efficiently generated with ultracold atoms confined in optical lattices, which are periodic potentials formed by laser interference. Two significant experimental hurdles impeding one-way computation in these systems are the inability to produce perfect cluster states and to perform single-qubit measurements. I will show that both of these can in fact be easily overcome using standard experimental techniques. I will also sketch out ideas about how to implement fault- tolerance within the one-way model.
