This talk will focus on the development of material platforms and physical mechanisms for high-fidelity control, storage, and transmission of quantum information. In particular, emerging quantum materials - novel diamond impurities - featuring long-lived, optically addressable quantum states are promising candidates fulfilling most of these requirements. We will discuss possible mechanisms for efficient interfacing of these novel solid-state qubits, in particular allowing for high-fidelity quantum-state transduction to superconducting qubits or to the long-lived nuclear spins. Finally, the physical phenomena enabling local quantum control in these materials, including strain-mediated or optically mediated state-transfer and two-qubit gates, will be discussed.
