Quantum Error Correction with a Globally-Coupled Array of Neutral Atom Qubits

This is the final report for the FA8750-09-1-0230, Quantum Error Correction with a Globally-Coupled Array of Neutral Atom Qubits. Under this project we developed and implemented an array of neutral atom qubits in optical traps for studies of quantum error correction. At the end of the three year project we were able to demonstrate preparation of a six qubit array in a two dimensional lattice with 4 micron site-to-site spacing. Numerical studies of quantum error correction QEC protocols were performed to determine the gate fidelity needed for useful error correction. A full experimental implementation of QEC is the subject of ongoing research in the Saffman labs at UW Madison.
