Nanoscale ion microtrap array for quantum information processing


A groundbreaking new device from the UK’s National Physical Laboratory NPL could help to usher in the long-awaited era of quantum computers.Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array that could be scaled up to handle several tens of ion-based quantum bits qubits.An ion trap is a combination of electric or magnetic fields that captures ions in a region of a vacuum the ions’ quantum state can be manipulated.The research shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device’s ability to confine individual ions at the nanoscale…
