论文摘要
提出了一项协议，以生成由两对旋转构成的三个逻辑Qubit的单线状态。研究了逻辑Qubits的单一操作和多个操作，以构建有效的哈密顿量，并通过基于不变的逆向工程和最佳控制来得出强大的控制场。此外，通过定期调制以获得更好的鲁棒性，进一步补偿了系统的错误。此外，还通过数值模拟显示了对协议的抗性的抗性。因此，该协议可以为旋转系统中的几代逻辑量子纠缠提供有用的观点。
A protocol is proposed to generate singlet states of three logical qubits constructed by pairs of spins. Single and multiple operations of logical qubits are studied for the construction of an effective Hamiltonian, with which robust control fields are derived with invariant-based reverse engineering and optimal control. Moreover, systematic errors are further compensated by periodic modulation for better robustness. Furthermore, resistance to decoherence of the protocol is also shown with numerical simulations. Therefore, the protocol may provide useful perspectives for generations of logical qubit entanglement in spin systems.
