摘要:

存储量子信息的延迟线对于推进量子中继器和硬件高效的量子计算机至关重要。传统上,它们被实现为支持波传播的扩展系统,但对传播场的控制有限。在此,我们引入了一种适用于微波光子的参数寻址延迟线,它对存储脉冲提供了高度控制。通过参数驱动一个与谐振器集合弱混合的三波混频电路元件,我们设计了一种模拟物理延迟线的频谱响应,同时能够快速控制延迟线的特性。我们通过选择发射哪个光子回波、在时间上平移脉冲,甚至交换两个脉冲来展示这种新颖的控制程度,所有这些操作的脉冲能量都在单光子量级。我们还测量了参数相互作用引入的噪声,发现其远小于一个光子。

英文摘要:

Delay lines that store quantum information are crucial for advancing quantum repeaters and hardware efficient quantum computers. Traditionally, they are realized as extended systems that support wave propagation but provide limited control over the propagating fields. Here, we introduce a parametrically addressed delay line for microwave photons that provides a high level of control over the stored pulses. By parametrically driving a three-wave mixing circuit element that is weakly hybridized with an ensemble of resonators, we engineer a spectral response that simulates that of a physical delay line, while providing fast control over the delay line's properties. We demonstrate this novel degree of control by choosing which photon echo to emit, translating pulses in time, and even swapping two pulses, all with pulse energies on the order of a single photon. We also measure the noise added from our parametric interactions and find it is much less than one photon.
