| Title: | Scalable Architecture of Assembled Single-Atom Qubit Arrays in Two and Three Dimensions |
| Abstract: | Through significant recent progress, regular registers of individual neutral atoms have established themselves as an auspicious platform for quantum technological applications. Hundreds of quantum bits (qubits) are available routinely. The marks of 1.000 qubits in 2D [1] and 10.000 qubits in 3D [2] have been passed recently, and 100 thousands of individual-atom quantum systems are within reach by extension of currently available technology. One-qubit gate operations are induced by electromagnetic fields and two-qubit gates are achieved by direct mutual interaction of neighboring atoms in highly-energetic internal states. I will discuss the physical principles and technological basis for quantum technology with neutral atoms cooled close to absolute zero temperature, held in vacuum, and trapped by light. I will present a scalable quantum information processing architecture based on advanced optical and quantum optical technologies. This platform is perfectly suited for applications in quantum simulation and quantum computing with individual atoms [1,2] and atom ensembles [3]. A proof of concept experiment has been performed to demonstrate the application of arrays of individual atoms in quantum sensing [4]. |
