Quantum frequency combs are a useful resource for parallel quantum communication and processing, given the robustness and easy handling offered by the frequency degree of freedom. In this work, we propose a method to generate broadband biphoton frequency combs and control their symmetry under particle exchange, based on purely passive optical components, such as a cavity and an optical delay line. We experimentally demonstrate our method using an integrated AlGaAs semiconductor platform producing quantum frequency combs, working at room temperature and compliant with electrical injection. We show the generation and manipulation of biphoton frequency combs, spreading over more the 500 peaks. These results open interesting perspectives for the development of massively parallel and reconfigurable systems for complex quantum operations.

鉴于频率自由度提供的鲁棒性和易于处理，量子频率梳是并行量子通信和处理的有用资源。在这项工作中，我们提出了一种基于纯无源光学组件（例如腔体和光学延迟线）的宽带双光子频率梳的生成方法，并在粒子交换下控制其对称性。我们通过实验证明了使用集成的AlGaAs半导体平台产生的量子频率梳，在室温下工作并符合电注入的方法。我们展示了双光子频率梳的产生和操作，它们分布在500个以上的峰中。这些结果为开发用于复杂量子操作的大规模并行和可重配置系统打开了有趣的前景。
