论文摘要
量子对象的相互作用位于基本量子物理学的核心,并且是广泛的量子信息技术的关键。光子量子 - 发光体相互作用是研究最广泛的。在静态定义良好的状态下,通常将两个Qubit的相互作用简化为两个量子对象。在这项工作中,我们探讨了一种从根本上进行新的动态类型的自旋光子相互作用。我们证明了与另一个真正的量子对象(具有基态自由度的量子点)对相干窄带波袋的调制。结果是波袋相的量子调制(0或π,但之间没有值),这是一种无法经典描述的新的光量子状态。
The interaction of quantum objects lies at the heart of fundamental quantum physics and is key to a wide range of quantum information technologies. Photon-quantum-emitter interactions are among the most widely studied. Two-qubit interactions are generally simplified into two quantum objects in static well-defined states . In this work we explore a fundamentally new dynamic type of spin-photon interaction. We demonstrate modulation of a coherent narrowband wavepacket with another truly quantum object, a quantum dot with ground state spin degree of freedom. What results is a quantum modulation of the wavepacket phase (either 0 or π but no values in between), a new quantum state of light that cannot be described classically.
