Network Architecture and Protocols

Our goal is to develop an understanding of scalable quantum communication network architectures and protocols from the perspective of less studied dimensions of scalability such as interoperability (heterogeneity of devices), number of users, diversity of services provided to users, and resilience.

To achieve this, we will revisit the state-of-the-art in quantum network architectures using a systems approach to go beyond long chains of repeaters and replicas of the classical TCP/IP stack. We will design and implement quantum networking protocols on our fiber optics network testbed. Simultaneously, we will study design options for network architectures and protocols at scale using SeQUeNCe, a discrete event simulator of quantum networks developed at Argonne.
