New Qudev website!

Welcome on the new Qudev website! We updated our website to a new software version and re-imagined the design!

We are still fixing a few final items, so do not wonder if parts of the website do not work yet as intended!

New quantum computing project launched

The Quantum Device Lab has been granted the project SuperMOOSE by IARPA, the US research funding agency. Coordinated by our group, the project aims to establish a connection between two error-corrected qubits, laying the foundation for future quantum computers. Our team collaborates with researchers from MIT, Forschungszentrum Jülich, Université de Sherbrooke in Canada and two industry partners, Zurich Instruments and Atlantic Quantum.

Loophole-free Bell inequality violation with superconducting circuits

Researchers from our group have demonstrated that superconducting circuits separated by a cryogenic link spanning a distance of 30 metres can be much more strongly correlated with each other than is possible classically. This loophole-free Bell test firmly establishes non-locality is a resource in quantum information technology based on superconducting circuits.
