Nonlocality: Driver for Quantum Advantage?

When talking about quantum technologies, the words quantum advantage usually follow
close behind: solving problems more efficiently than with classical alternatives is one of the
main drivers of this research field. While much desired, there are no clear insights into the
reasons why some algorithms or protocols have a quantum advantage and others do not.

This interdisciplinary workshop brings together researchers from quantum computing,
quantum communication, and the foundations of quantum mechanics to explore the
fundamental ingredients behind quantum advantage—the ability of quantum technologies to
outperform classical ones. While quantum advantage has been demonstrated in laboratory
settings, it remains an open question which quantum features—such as entanglement,
magic, or Bell nonlocality—are truly essential for achieving practical benefits.

A key focus of the workshop is to connect the quantum computing community with experts in
quantum nonlocality and device-independent quantum information processing, a subfield
where security and performance can be guaranteed without trusting the inner workings of
the devices used. This connection is timely, as recent research suggests that quantum
nonlocality may play a crucial role in the expressiveness and power of quantum
technologies, including quantum machine learning. 

The workshop will encourage collaboration, foster new insights, and produce a curated
Zotero library of foundational and emerging scientific papers—with comments from
participants—to support ongoing and future research.
