报告摘要:Quantum control of systems plays an important role in modern science and technology. We focus in the spins in solids which are important platforms for quantum information science. In this talk, I would like to present our recent progress in quantum control over spins in nitrogen-vacancy centers in diamonds [1-4]. The initialization, readout and high-fidelity quantum gate operations of spin qubits can be accomplished by advanced spin resonance techniques. Our recent experiment which is to achieve the quantum control beyond Hermitian Hamiltonians will also be discussed [5].
