摘要

Abstract

High-dimensional quantum states are known to offer advantages over their two-dimensional qubit counterparts

but their preparation and manipulation has been bulky and cumbersome. Now

quantum state control has been demonstrated on-chip with a ~1 μm

footprint and nm-scale features

producing up to eight-dimensional quantum states and ushering in a new route to large quantum information encoding on a small footprint.
