论文摘要
我们通过实验研究了由固定频率transmon量子的基本物理哈密顿量的变异量子栅极优化方案的生存能力。通过在天然交叉谐振相互作用上量身定制的两个和三个量子量子门的成功实验优化，证明了该方案的效用。通过基于Floquet工程的三Q量相互作用的优化栅极进行优化，研究了这种策略的限制，但是参数漂移被确定为一个关键限制因素，以阻止实现这种方案，而该方案变异优化协议无法克服。
We experimentally investigate the viability of a variational quantum gate optimization protocol informed by the underlying physical Hamiltonian of fixed-frequency transmon qubits. The utility of the scheme is demonstrated through the successful experimental optimization of two and three qubit quantum gates tailored on the native cross-resonance interaction. The limits of such a strategy are investigated through the optimization of a gate based on Floquet-engineered three-qubit interactions, however parameter drift is identified as a key limiting factor preventing the implementation of such a scheme which the variational optimization protocol is unable to overcome.
