论文摘要
我们提出了使用飞秒激光写作技术制造的两分光子量子处理器的实验实现。我们采用飞秒激光写作来创建一个低损坏的可重新配置的光子芯片，以实现精确的单量和两Q量操作。单量和两倍门的性能的特征是完整的过程断层扫描。证明了处理器在使用变异量子本质量算法确定H2分子的基态能量中的示例应用。我们的结果突出了飞秒激光写作技术的潜力，即提供高质量的小型量子光子处理器。
We present an experimental implementation of a two-qubit photonic quantum processor fabricated using femtosecond laser writing technology. We employ femtosecond laser writing to create a low-loss reconfigurable photonic chip implementing precise single-qubit and two-qubit operations. The performance of single-qubit and two-qubit gates is characterized by full process tomography. An exemplary application of the processor to determining the ground state energy of an H2 molecule using the variational quantum eigensolver algorithm is demonstrated. Our results highlight the potential of femtosecond laser writing technology to deliver high quality small-scale quantum photonic processors.
