Abstract

Section titled “Abstract”

We propose a novel architecture for scalable quantum computation based on\nquantum actuated decoherence-free (DF) qubits. Each qubit is encoded by the DF\nsubspace of a nuclear spin pair and has long coherence time. A nitrogen-vacancy\ncenter in diamond is chosen as the quantum actuator to realize initialization,\nreadout and universal control of DF qubits with fidelities higher than 99%. It\nreduces the challenge of classical interfaces from controlling and observing\ncomplex quantum systems down to a simple quantum actuator. Our scheme also\nprovides a novel way to handle complex quantum systems.\n
