An ion-trap chip with integrated elements for a scalable quantum processor — •Benjamin Bürger, Ivan Boldin, Christof Wunderlich, Saptarshi Biswas, and Daniel Busch — University of Siegen, Germany

Scaling up a trapped ion-based quantum information processing to hundreds of qubits could be achieved by arranging several trapping zones on an ion-trap-chip. The zones can be entangled by means of shuttling ions between the zones [1]. Here, we use hyperfine levels as qubits of 171Yb+ ions trapped in a planar microstructured trap with MAgnetic Gradient Induced Coupling (MAGIC) between them [2]. We report on the design and characterization of this novel trap chip that includes an integrated microwave electrode for efficient single-qubit manipulations, permanent magnets for creating a field gradient of 100 T/m required for multi-qubit gates via MAGIC, and an ion transport zone for testing the qubit coherence properties when shuttling the ion in and out of the interaction zone. The trap chip is designed to serve as a basis for a up-scalable device.
