Objective
We will develop a novel very promising approach to quantum information processing (QIPC): Neutral-atom manipulation using integrated micro-devices, combining the best of both worlds: The tools of quantum optics and the long coherence times and very high precision of neutral atom manipulation for the quantum part of the information processing with the vast technology of integrated optical and electronic elements for classical part of the atom manipulation. Together it will be integrated in one single ATOMICS chip, which can be produced using nanofabrication technology. We expect this new technology to have a large impact also for other quantum optics approaches, to QIPC and moreover enable new fundamental experiments and novel devices using neutral atoms.
OBJECTIVES
The key objective of this consortium is to develop the technology for using neutral atoms in microscopic traps for QIPC. Integrated in one single nanofabricated ATOMICS chip we will combine the long coherence times and very high precision of neutral atom manipulation for the quantum part of the information processing with the vast technology of integrated optical and electronic elements for classical part of the atom manipulation. We will assess this technology for its applicability to create a toolbox from which one can start building QIPC devices. To achieve this we have to develop microscopic, controllable and qubit selective traps, and adapt methods to preparing, manipulating and detecting qubits to these micro traps. Moreover we will study the decoherence mechanisms for neutral atoms in micro traps and gain deeper theoretical understanding of QIPC with micro traps, with special emphasis on the scalability and massive parallelism achievable with nanofabricated devices.
DESCRIPTION OF WORK
We will combine expertise in the fields of experimental and theoretical quantum optics, nanofabrication technology and integrated optics. Our research will first concentrate on developing the components of an ATOMICS chip on a broad basis, which will be integrated together one by one as the project progresses. This technology will then be applied to atom manipulation and QIPC. Our main focus will be: - Developing magnetic and electric micro traps and guides with sub 100 nm ground state size, based on surface mounted, charged and current carrying nanostructures (similar to quantum wires or quantum dots of mesoscopic quantum electronics). Emphasis being on microscopic controllable and qubit selective traps and on technologies, which will allow to integrate electronics and optics; - Combining micro traps with integrated optics and optoelectronics and micro- electronics on the same ATOMICS chip; - Develop atom detection in micro traps by adapting various known techniques from standard quantum optics. With emphasis of integrating them in the ATOMICS chip; - Study the decoherence mechanisms for neutral atoms in micro traps and learn how to control or prevent decoherence; - Adapt methods to effectively prepare and manipulate qubits; - 1 and 2-qubit operations, entangling neutral atoms in micro traps; - Gain deeper theoretical understanding of the physics involved in QIPC and in QIPC with micro traps in particular. We will put special emphasis on realistic calculations and study the promise of scalability and massive parallelism of nanofabricated devices; - Assessing the possibilities of a final ATOMICS chip for the various aspects of QIPC ranging from small devices like a repeater for quantum communication to scaleable and massively parallel designs. This will include also the advantages of ATOMICS for other quantum optics or atom based QIPC proposals.
