摘要:

量子物体的相互作用是基础量子物理学的核心,也是广泛的量子信息技术的关键。光子-量子-发射极相互作用是研究最广泛的。两个量子比特的相互作用通常被简化为两个量子对象在静态定义良好的状态。在这项工作中,我们探索了一种全新的动态类型的自旋光子相互作用。我们演示了一个相干窄带波包与另一个真正的量子对象,一个具有基态自旋自由度的量子点的调制。结果是波包相位的量子调制(0或π,但没有介于两者之间的值),一种新的光的量子态,不能用经典描述。

英文摘要:

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.
