Abstract Understanding and controlling non-equilibrium dynamics in quantum many-body systems is a fundamental challenge in modern physics1,2,3,4,5, with profound implications for advancing quantum technologies. Typically, periodically driven systems in the absence of conservation laws thermalize to a featureless ‘infinite-temperature’ state, erasing all memory of their initial conditions6,7,8.

Abstract Recent efforts have succeeded in producing quantum networks in which quantum information can be stored, transferred and processed across multiple nodes on a metropolitan scale. A key remaining challenge is to enhance the capabilities of individual nodes, providing precise and robust control over multiple qubits. Here we demonstrate coherent control in a hybrid quantum node based on a diamond colour centre.
