Scalable Quantum Processor Technology Based on Laser Trapped Neutral Atoms
Abstract
This grant has supported an extensive effort aimed at using laser cooled Cs atoms trapped in optical lattices as qubits, and to demonstrate basic single- and two-qubit quantum gates. During the grant period we have made significant progress towards these goals. We have: (i) Refined or developed new essential diagnostic tools for atomic qubits, including Stern-Gerlach analysis and real-time QND measurements. (ii) Developed techniques to trap atomic qubits in 3D optical lattices, and to cool and initialize them in one of the logical basis states. (iii) Developed techniques for robust single-qubit manipulation based on plain or composite microwave pulses. In addition, new conceptual developments have occurred and our perspective on two-qubit gates and experiments to test them have evolved considerably. During the coming year we hope to demonstrate a non-separable twoatom phase gate based on controlled ground state collisions, and to observe a new phenomenon known as a trap-induced shape resonance that may provide new freedom to design high-fidelity quantum logic.
