For thousands of years, code-makers and code-breakers have been competing for supremacy. With the advent of the internet, the importance of encryption is growing. Unlike conventional cryptography, quantum cryptography offers unconditional security based on the laws of physics. This research program addresses a wide range of important unresolved problems in quantum cryptography. It involves research in theory, simulations and experiments. On the theory side, we plan to study the fundamental question of the connection between quantum correlations called entanglement and quantum secret sharing. On the simulation side, we will study the performance of practical quantum cryptographic systems. On the experimental side, we plan to design and build a high-speed quantum cryptographic network using continuous variables, thus enabling quantum communication with existing fibre networks. As a spin-off technology, we will build a robust, low-cost, high-speed quantum random number generator, which has widespread applications in cryptography, simulations and on-line gaming. A particular strength of our program is our expertise in quantum hacking and counter-measures against it. In fact, a centrepiece of our new research program is the study of the strengths and weaknesses of an entirely type of quantum cryptographic protocols based on "measurement-device-independent" quantum key distribution. Here, we aim at building new type of quantum key distribution systems with unmatched security and performance. Our work not only contributes to fundamental research, but also may incubate the first Canadian commercial quantum key distribution systems.

几千年来，密码制定者和密码破译者一直在争夺霸权。随着互联网的出现，加密的重要性越来越大。与传统密码学不同，量子密码学提供了基于物理定律的无条件安全性。该研究计划解决了量子密码学中广泛的重要未解决问题。它涉及理论，模拟和实验研究。 在理论方面，我们计划研究被称为纠缠的量子关联和量子秘密共享之间的联系的基本问题。在模拟方面，我们将研究实际量子密码系统的性能。在实验方面，我们计划使用连续变量设计和构建一个高速量子加密网络，从而实现与现有光纤网络的量子通信。作为一项衍生技术，我们将建立一个强大的，低成本的，高速的量子随机数发生器，它在密码学，模拟和在线游戏中有广泛的应用。 我们的项目的一个特别优势是我们在量子黑客和反措施方面的专业知识。事实上，我们新研究项目的核心是研究基于“测量设备无关”量子密钥分配的完全类型的量子密码协议的优点和缺点。在这里，我们的目标是构建具有无与伦比的安全性和性能的新型量子密钥分发系统。我们的工作不仅有助于基础研究，而且可能孵化加拿大第一个商业量子密钥分发系统。
