论文摘要
控制光的波形是经典和量子电子中多功能光源的关键。尽管经典光的脉冲塑形是一种成熟的技术，并且已在各个领域中使用，但更高级的应用将由带有任意时间波形的任意量子光的光源实现。我们将这种设备称为量子任意波形发生器（Q-AWG）。 Q-AWG必须能够处理脆弱的光量子状态。因此，Q-AWG需要与经典脉冲塑造的根本不同的方法。在本文中，我们发明了一个Q-Awgs的架构，可以在本金中以与GHz相比的重复率进行半决赛操作。我们通过生成具有以前从未实现过的波形的高度非古典状态来证明其核心技术。该结果将导致基于Q-AWG（例如实用光学量子计算）的强大量子技术。
Controlling the waveform of light is the key for a versatile light source in classical and quantum electronics. Although pulse shaping of classical light is a mature technique and has been used in various fields, more advanced applications would be realized by a light source that generates arbitrary quantum light with arbitrary temporal waveform. We call such a device a quantum arbitrary waveform generator (Q-AWG). The Q-AWG must be able to handle versatile quantum states of light, which are fragile. Thus, the Q-AWG requires a radically different methodology from classical pulse shaping. In this paper, we invent an architecture of Q-AWGs that can operate semi-deterministically at a repetition rate over GHz in principal. We demonstrate its core technology via generating highly non-classical states with waveforms that have never been realized before. This result would lead to powerful quantum technologies based on Q-AWGs such as practical optical quantum computing.
