This NSF award aims to further our understanding of quantum information theory and quantum communication. All of the work proposed is theoretical in nature, but some of the threads are practical and may find future application in quantum communication systems. At the same time, there is a strong educational component to this award in line with the vision of the PI to establish Louisiana State University as a leading center for quantum information research and study.This award first seeks to sharpen our understanding of the limitations on communication using quantum-mechanical systems as the carriers of information. The PI will do so by proving so-called "strong converse" theorems for various communication capacities of quantum channels. The quantum information community now understands the communication capacities of several channels well, but what is lacking in some cases is a strong converse theorem. These theorems are conceptually rich, and they also find application in proving the security of particular models of cryptography. The PI will also investigate areas such as lossy quantum data compression theory and quantum communication over networked systems. Both topics are foundational in the subject and will likely underly future quantum technologies. The important theoretical questions in these respective fields are still left unanswered and the research conducted on behalf of this award will offer several ways of addressing them. The PI also will consider new exciting communication capacity questions to consider, such as the "locking capacity" of a quantum channel for sending data securely. The PI also seeks to improve the understanding of the practically relevant class of optical communication channels, which underly free-space or fiber-optic communication technologies.The broader significance of this award is in line with the NSF Mission "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense; and for other purposes." Indeed, research at the intersection of physics, information theory, computer science, and mathematics has advanced science in remarkable ways, pushing the limits of what is possible experimentally and what is possible in principle. Research in quantum communication is critical to national defense as well, given the important application of quantum secured communication. The PI will be advising and teaching several graduate students in the quantum science and technologies group at Louisiana State University.

NSF奖的目的是进一步了解量子信息理论和量子交流。所提出的所有工作本质上都是理论上的，但是某些线程是实用的，可能会在量子通信系统中找到未来的应用。同时，该奖项具有强大的教育成分，这与PI的愿景一致，即在Louisiana State University成为量子信息研究和研究领先的领先中心。该奖项首先旨在加深我们对使用量子力学系统作为信息载体的通信限制的了解。 PI将通过证明量子通道各种通信能力的所谓“强匡威”定理来做到这一点。量子信息社区现在很好地了解了几个渠道的沟通能力，但是在某些情况下缺少的是强烈的匡威定理。这些定理在概念上是丰富的，他们还发现了证明特定密码学模型的安全性的应用。 PI还将研究网络系统上的量子数据压缩理论和量子通信等领域。这两个主题都是该主题的基础，并且可能会在未来的量子技术中基础。这些各自领域的重要理论问题仍未得到答复，代表该奖项进行的研究将提供几种解决方案的方法。 PI还将考虑要考虑的新的令人兴奋的通信能力问题，例如量子通道的“锁定能力”以安全地发送数据。 PI还试图提高对实际相关类别的光学通信渠道类别的理解，这些光学通信渠道是基本的自由空间或光纤通信技术。该奖项的更广泛的意义与NSF的任务一致，以促进科学的进步；促进国民健康，繁荣和福利；为了获得国防；为了获得国防；实际上，在物理学，信息理论，计算机科学和数学交集的研究中，科学以非凡的方式提高了科学，从而推动了实验和原则上可能的可能性的限制。鉴于量子安全的重要应用，量子交流的研究也对国防部也至关重要。 PI将为路易斯安那州立大学量子科学和技术小组的几名研究生提供建议。
