Individual addressing of trapped 171 Yb+ ion qubits using a microelectromechanical systems-based beam steering system

Journal Article (Journal Article)

The ability to individually manipulate the increasing number of qubits is one of the many challenges towards scalable quantum information processing with trapped ions. Using micro-mirrors fabricated with micro-electromechanical systems technology, we focus laser beams on individual ions in a linear chain and steer the focal point in two dimensions. We demonstrate sequential single qubit gates on multiple 171Yb+ qubits and characterize the gate performance using quantum state tomography. Our system features negligible crosstalk to neighboring ions (<3 × 10-4), and switching speed comparable to typical single qubit gate times (<2 μs).
