论文摘要
量子信息科学和强烈的激光物质相互作用是两个显然无关的领域。在这里，我们通过提供原子中高谐波产生的测量协议的量子机械描述来介绍量子信息理论的概念，以激光驱动的过程。这允许构想新协议，用于量子状态工程的光。我们在单个光场模式上明确评估调节实验，并为相干状态提供相应的量子操作。获得了相关的正算子估算措施，并引起了高维纠缠状态的产生的量子测量理论，并在Attosecond时期尺度上具有可控的非经典特征的相干状态叠加。这确立了将激光驱动的过程用作量子信息处理的新型量子技术平台。
Quantum information science and intense laser matter interaction are two apparently unrelated fields. Here, we introduce the notion of quantum information theory to intense laser driven processes by providing the quantum mechanical description of measurement protocols for high harmonic generation in atoms. This allows to conceive new protocols for quantum state engineering of light. We explicitly evaluate conditioning experiments on individual optical field modes, and provide the corresponding quantum operation for coherent states. The associated positive operator-valued measures are obtained, and give rise to the quantum theory of measurement for the generation of high dimensional entangled states, and coherent state superposition with controllable non-classical features on the attosecond timescale. This establish the use of intense laser driven processes as a novel quantum technology platform for quantum information processing.
