Quantum information encoded in relative degrees of freedom of multiple quantum systems offers striking advantages in communication and cryptography: it is immune to common types of noise and does not require reference systems shared between parties. This project aims to formulate a theory of relative quantum information, to develop practical information processing protocols that take advantage of relative encodings, and to propose proof-of-principle experiments in quantum optics that reveal these advantages. Expected outcomes include powerful communication and cryptographic protocols, a design for programmable quantum computation, and a fundamentally relative theory of quantum information connecting with other foundational fields of physics.

以多个量子系统的相对自由度编码的量子信息在通信和密码学方面具有显着的优势：它不受常见类型噪声的影响，并且不需要在各方之间共享参考系统。 该项目旨在制定相对量子信息理论，开发利用相对编码的实用信息处理协议，并提出揭示这些优势的量子光学原理验证实验。 预期成果包括强大的通信和加密协议、可编程量子计算的设计以及与其他基础物理领域相连接的量子信息的基本相关理论。
