Workshop “Quantum Information: Entanglement of Mathematics & Physics” Held at UBC

From September 21 to 23, 2026, iTHEMS held the workshop “Quantum Information: Entanglement of Mathematics & Physics” at the University of British Columbia (UBC) in Vancouver, Canada.

The workshop brought together researchers in mathematics and physics to foster cross-disciplinary discussion through the shared lens of quantum information. Its wide-ranging program covered operator algebras, quantum resource theories, quantum gravity, condensed-matter physics, quantum computing, and quantum error correction. Participants discussed entanglement in these different fields and the mathematical structures underlying quantum information.

Approximately 40 researchers from iTHEMS, UBC, and other universities and research institutions in Japan and Canada participated in the workshop. Over the three days, 21 talks were presented. Generous time was also allocated each day for discussion, allowing participants from different fields to share their perspectives and research methods and to engage in lively exchanges.

Viewing the participants’ research through the common perspective of quantum information revealed many concrete ways in which insights and methods from distinct fields can complement one another. The broad range of expertise represented by researchers from Japan and Canada gave depth to the discussions and enabled an organic exchange of ideas, with candid questions and challenges addressed across disciplinary boundaries.

On the final day, a plenary discussion entitled “Entanglement across mathematics and physics; future iTHEMS–UBC collaboration” explored how the exchanges initiated at the workshop could lead to future research collaboration between iTHEMS and UBC. The workshop also provided a valuable opportunity to build relationships toward sustained academic exchange and a possible Memorandum of Understanding (MOU) between the two institutions.

By connecting diverse areas of mathematics and physics through quantum information, the workshop expanded opportunities for new exchanges and collaborative research, while further strengthening the partnership between iTHEMS and UBC.
