Third Workshop for Quantum Repeaters and Networks (WQRN3)

August 19-21, 2022

Location: David Rubenstein Forum at the University of Chicago, 1201 E 60th St, Chicago, IL 60637

We are pleased to invite you to Third Workshop for Quantum Repeaters and Networks (WQRN3), to be held in Chicago, Illinois, August 19-21, 2022. The workshop will be held in person only and is locally organized by the Chicago Quantum Exchange and Q-NEXT.

The 1998 proposal introducing a quantum repeater resulted in high-profile efforts on vital components needed to establish a multi-node quantum network. Quantum repeaters utilize quantum entanglement, quantum memories, techniques for suppressing quantum errors and quantum teleportation to dramatically enhance both the reach and bit rate of quantum communication. Various experimental schemes have been proposed and components developed, and early experimental efforts are working towards the realization of a quantum repeater. Despite the progress, significant challenges remain, first in proof-of-principle demonstrations and then in the development of practical systems adequate for deployment in the field.

The goal of this workshop is to bring the active research community together to discuss the progress, challenges and new possible directions for quantum repeaters and networks. We invite participation from researchers working on key enabling technologies and system integration, protocols for connecting repeaters across network links with high fidelity, architectures for large-scale networks, and applications of distributed quantum entanglement.

A tutorial titled Quantum Repeater Networks from Scratch will be held prior to WQRN3. No quantum experience is necessary. Separate registration is required. Learn more
