  • Workshop for Quantum Repeaters and Networks

    (WQRN)

  • About WQRN

    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 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.

    The WQRN has been and continues to be a limited-attendance, few-day workshop, in which participants are given the opportunity to share ideas, directions, and concerns to advance the state of the field. Talks are by invitation only and catered to broadly cover the applications, theory, components, and worldwide directions in quantum repeaters and networks. These talks frame group discussion sessions for which all participants are welcome to contribute; participants are also welcome to contribute to a poster session.

    UPDATE (May 13, 2025): We are delighted to announce the new members of the WQRN Steering Committee. Joining us for the next several WQRNs will be Dr. Masahiro Takeoka from the Keio University in Japan, Dr. Elizabeth Goldschmidt from the University of Illinois in the USA, Dr. Alex Ling from the Center for Quantum Technologies at the National University of Singapore in Singapore and Dr. Urbasi Sinha from the Raman Research Institute in India. These esteemed colleagues will join current SC members Dr. Oliver Slattery of the National Institute of Standards and Technology in the USA, Dr. Saikat Guha from the University of Maryland in the USA, Dr. Hugues de Riedmatten from the Institute of Photonic Sciences in Spain, Dr. Eleni Diamanti from Sorbonne University in France and Dr. Paul Kwiat from the University of Illinois in the USA.

    UPDATE (May 6, 2025): The WQRN5 (2026) will be held from April 27th-29th, 2026 at 1 Rochester Park, Singapore. A website for the event will be established soon. Important dates will be listed here also in the coming weeks. Looking forward to seeing everyone in Singapore next April.

    UPDATE (March 4, 2025): The WQRN Steering Committee has selected Singapore as the location for WQRN5 (2026). The event will be hosted by the Center for Quantum Technologies at the National University of Singapore. More details will follow in the coming weeks.

    UPDATE: (February 10th, 2025): The call for host locations has now closed. Thanks to the those who submitted proposals. The Steering Committee are currently reviewing proposals and will select the WQRN-5 (2026) host by the end of February with notifications sent shortly thereafter.

    UPDATE (December 20th, 2024): The Workshop for Quantum Repeaters and Networks (WQRN) is requesting information from potential local organizers (LO) regarding hosting the next workshop in the series, expected to take place in 2026. The information requested does not constitute any form of obligation or binding proposal, but is rather an expression of interest and will be used as a guide by the WQRN steering committee (SC). The WQRN steering committee requests a brief (2 page) summary of location information by January 31st 2025. For more detailed instructions - please see here. Please direct responses by email to the WQRN steering committee at email address wqrn2026@gmail.com. Note: If you do not receive a confirmation within 2 business days, please contact Oliver Slattery at oliverslattery@gmail.com without including any attachment.
