摘要:

我们利用基于六通道微环谐振器的硅光子脉冲整形器实现了纠缠光子的光谱整形。通过对微谐振器脉冲整形器中的热相移器进行精确校准,我们在3 GHz网格上对两个频率 bin 纠缠 qudit 实现了逐行相位控制,对应于共享(独立)信号-闲置滤波器的高达6×6(3×3)维希尔伯特空间。脉冲整形器的精细光谱分辨率能够控制纳秒级时间特征,这通过双光子相关函数的直接符合检测观察到,其结果与理论高度一致。据我们所知,这项工作首次展示了使用集成光谱整形器进行双光子脉冲整形,在量子信息处理中具有重要应用前景。

英文摘要:

We demonstrate spectral shaping of entangled photons with a six-channel microring-resonator-based silicon photonic pulse shaper. Through precise calibration of thermal phase shifters in a microresonator-based pulse shaper, we demonstrate line-by-line phase control on a 3~GHz grid for two frequency-bin-entangled qudits, corresponding to Hilbert spaces of up to $6\times 6$ ($3\times 3$) dimensions for shared (independent) signal-idler filters. The pulse shaper's fine spectral resolution enables control of nanosecond-scale temporal features, which are observed by direct coincidence detection of biphoton correlation functions that show excellent agreement with theory. This work marks, to our knowledge, the first demonstration of biphoton pulse shaping using an integrated spectral shaper and holds significant promise for applications in quantum information processing.
