Quantum Logic with Trapped Atoms in Optical Cavity QED
Abstract
The principle goal of our program is the demonstration of scalable quantum logic between qubits encoded in the internal states of neutral atoms sharing the quantum field of an optical cavity. This requires successful integration of two leading quantum information technologies atom-based quantum memories and cavity QED-based entanglement generation and manipulation. We have developed methods for trapping atoms inside high-finesse optical resonators for scalable quantum logic. Our configuration employs infrared (CO2) laser traps for individual atoms that will permit us to store many individually addressable atoms and to manipulate these atoms in arbitrary combinations using the quantum field of the optical cavity. Importantly, the use of infrared trapping lasers virtually eliminates decoherence due to atomic spontaneous emission, which hinders many AMO-based systems.
