论文摘要
两频的时频纠缠是量子信息中的宝贵资源。但是，解决超短脉冲单光子的波袋是一个挑战。在这里，我们使用工程学参数下转换（PDC）和非线性波导中的量子脉冲门（PDC）和量子脉冲门（PDC）和量子频率域中的两光子量子相关性的远程光谱形状在时间频域中探测了两光子量子相关性。通过调整PDC源的关节光谱振幅函数，我们可以控制生成的光子对之间的时间模式结构，并在一系列时频模式叠加上显示远程状态项目。
Two-photon time-frequency entanglement is a valuable resource in quantum information. Resolving the wavepacket of ultrashort pulsed single-photons, however, is a challenge. Here, we demonstrate remote spectral shaping of single photon states and probe the coherence properties of two-photon quantum correlations in the time-frequency domain, using engineered parametric down-conversion (PDC) and a quantum pulse gate (QPG) in nonlinear waveguides. Through tailoring the joint spectral amplitude function of our PDC source we control the temporal mode structure between the generated photon pairs and show remote state-projections over a range of time-frequency mode superpositions.
