Quantum information science, a field that has emerged over the past several decades, addresses the question of whether harnessing quantum mechanical effects through storing, processing and transmitting information encoded in inherently quantum mechanical systems can lead to new phenomena, functionalities, and devices. Quantum information is both fundamental science and a progenitor for new technologies. Photonic quantum systems provide many advantages, reaching from low levels of decoherence to precise single-particle quantum control and being mobile. Unfortunately, quantum photonic experiments built with such bulk optics are limited by their space requirements. Integrated optics manufactured from monolithic blocks of material circumvents this.The aim of our proposal is to promote the understanding and control of waveguide architectures for coherent information transfer with the vision to establish a basis for new, quantum information processing applications. In particular, our research will address (1) Eigenstate formation and transmission in periodically driven lattice systems, (2) Tailored input state projection on system eigenstates, and (3) Transport studies of multi-photon states in lossy integrated optical networks.The main goal of our proposal is therefore to propose, implement and test a new approach for quantum information transfer. We will exploit the quantum eigenstates of the on-chip waveguide structures that in principle can travel indefinitely without any distortion due to their stationary nature. Apart from revealing new and fundamental scientific knowledge, which is based on our sophisticated approach of combining quantum state manipulation and optical integrated circuitry, our results will have immediate technological significance. We will combine the experimental work with theoretical analysis, in order to explain our results thoroughly and optimize device performance.

量子信息科学是在过去几十年中兴起的一个领域，它研究的问题是，通过存储、处理和传输内在量子力学系统中编码的信息来利用量子力学效应是否会导致新的现象、功能和设备。量子信息既是基础科学，也是新技术的先驱。光子量子系统提供了许多优势，从低水平的退相干到精确的单粒子量子控制，并且是可移动的。不幸的是，用这种体光学建立的量子光子实验受到空间要求的限制。我们建议的目的是促进对相干信息传输的波导结构的理解和控制，以期为新的量子信息处理应用奠定基础。特别是，我们的研究将涉及(1)周期驱动格子系统本征态的形成和传输，(2)系统本征态的定制输入态投影，以及(3)有损集成光网络中多光子态的传输研究。因此，我们的建议的主要目标是提出、实现和测试一种新的量子信息传输方法。我们将利用片上波导结构的量子本征态，由于其静止的性质，原则上可以无限旅行而不会发生任何失真。除了揭示新的基础科学知识，这是基于我们结合量子态操纵和光学集成电路的复杂方法，我们的结果将具有直接的技术意义。我们将把实验工作和理论分析结合起来，以便更好地解释我们的结果，优化器件性能。
