QuantAlgo: Quantum algorithms and applications

在20世纪，信息技术的发展不仅对科学，而且对整个社会都产生了巨大的影响。这场史无前例的革命表明，需要提高数据处理的速度和效率，以及努力实现更好的安全和隐私。当前信息处理模型的一个终极限制是，它们假定物理的简化表示，依赖于经典力学。量子信息技术承诺通过实现物理定律所允许的最高安全和效率来打破这一障碍，从而导致一场新的信息技术革命，其形式是由经典和量子计算设备组成的大规模网络，能够高效和安全地利用量子资源来通信和处理海量数据。尽管实验稳步取得进展，但我们距离这一长期愿景还很远，这不仅是因为技术上的限制，也是因为当前量子算法的应用范围仍然很窄。该项目的愿景是将量子算法基础的研究与开发针对大数据和机器学习等极端实用重要性和及时性领域的新应用相结合。该项目将通过提供新的软件工具来补充正在进行的量子技术实验工作，以帮助导致信息技术革命，利用量子资源的力量远远超出当今的能力，同时保持安全的数字社会。

During the 20th century, the development of information technologies had a huge impact not only on science but also on society as a whole. This unprecedented revolution revealed a need to improve the speed and efficiency of data processing, as well as to strive for better security and privacy. One ultimate limitation of current information processing models is that they assume a simplified representation of physics, relying on classical mechanics. Quantum information technologies promise to break this barrier by achieving the highest security and efficiency allowed by the laws of physics, hence leading to a new revolution in information technologies, in the form of a large-scale network of classical and quantum computing devices able to communicate and process massive amounts of data both efficiently and securely using quantum resources. Despite steady experimental progress, we are still far from this longterm vision, not only due to technological limitations but also to the still-narrow range of applications of current quantum algorithms.The vision of this project is to combine research on the fundamentals of quantum algorithms with the development of new applications targeted at areas of extreme practical importance and timeliness such as big data and machine learning. The project will complement ongoing experimental efforts in quantum technologies by providing new software tools in order to help lead to a revolution in information technologies, harnessing the power of quantum resources to go well beyond today's capabilities, while maintaining a secure digital society.
