@article{Weitenberg2011QuantumCA, title={Quantum computation architecture using optical tweezers}, author={Christof Weitenberg and Stefan Kuhr and Klaus M{\o}lmer and Jacob Friis Sherson}, journal={Physical Review A}, year={2011}, volume={84}, pages={032322} }

We present a complete architecture for scalable quantum computation with ultracold atoms in optical lattices using optical tweezers focused to the size of a lattice spacing. We discuss three different two-qubit gates based on local collisional interactions. The gates between arbitrary qubits require the transport of atoms to neighboring sites. We numerically optimize the nonadiabatic transport of the atoms through the lattice and the intensity ramps of the optical tweezer in order to maximize…
