"hear echo of own signals, creating self-interaction protecting quantum information/ providing form of system memory... multiple natural atoms share single quantum state, enabling quantum information from multiple qubits to be stored/ controlled without need for increasingly complex external circuitry... scalable hybrid approach facilitates entanglement distribution... highly stable... potentially connecting different types of quantum technologies... large-scale quantum computing over longer distances"
