. . . . . Quantum computing. Research update. New ion trapping approach could help quantum computers scale up. 25 Mar 2024 Ions on the move: To create this image, the ETH Zürich researchers repeatedly transported a single trapped ion from its initial position (red circle) to 58 other positions, imaged it in its new location, and returned it to its starting point.
