Quantum Information Processing with Microoptical Elements — •Felix B.J. Buchkremer, Rainer Dumke, Tobias Müther, Michael Volk, Gerhard Birkl, and Wolfgang Ertmer — Institut für Quantenoptik, Universität Hannover, Welfengarten 1, 30167 Hannover, Germany

Using neutral atoms as the carriers of the qubits of quantum information processing requires efficient means for the preparation, manipulation, and storage of qubits inscribed into atoms as well as schemes for the entanglement of atoms, the implementation of two- and multiple-bit quantum gates, and the read-out of quantum information. We introduce the application of microoptical elements to quantum information processing with atoms and discuss the advantages and the inherent potential of this new approach [1]. As a first step, we experimentally investigate the applicability of microoptical elements to create multiple far-detuned dipole potentials with possible applications for storing and transfering qubits inscribed into atoms. In addition, we discuss how microoptical elements can be used for the implementation of two-qubit gates as well as for the efficient manipulation and read-out of qubits. The intrinsic design flexibility and scalability of microoptical elements open the possibility for compact, integrated setups for quantum information processing. Supported by the program ACQUIRE (IST-1999-11055) of the European Commission.
