AVAQUS Receives Six-Month Extension, New Project End Date Announced (August 2023)
In August 2023, the AVAQUS project received a six-month extension, pushing the new project end date to September 30, 2024. This change means that in addition to the previously scheduled review in November 2023, there will be another review in one year, which will be the final review. Details of the extension are expected to be announced in the near future, providing more time to successfully complete the AVAQUS project.
AVaQus at the Spring School on Superconducting Qubit Technology (April 2023)
The Spring School on Superconducting Qubit Technology was organized in Benasque, Spain on April 11 -- Apr 21 2023 by Pol Forn-Díaz, David López-Núñez and Fabian Zwiehoff (IFAE, Barcelona)
The AVaQus meeting took place during the school in the Centro de Ciencias de Beasque Pedro Pascual. It was the firs in-person meeting of the project.
Project advisors advisors Frank Wilhelm (Jullich, Germany), Arkady Fedorov (University of Queensland, Australia) and Tsuyoshi Yamamoto (NEC, Japan) attended the meeting.
The IFF-CSIC Group, partner of AVaQus, Leads Breakthrough in Quantum Annealing Research (February 2023)
The Madrid-based Instituto de Física Fundamental (IFF-CSIC) group, led by Juanjo García-Ripoll, has published a study in Physical Review Letters. They have discovered a more efficient method for generating thermal quantum states using quantum annealers, the type of quantum computers develped in the contextx of AVaQus. This discovery represents a significant advancement in quantum computing technology, as it outperforms conventional computers in the generation of quantum thermal states. You can find the full reference and details of their research in the following link.

Operating in a deep underground facility improves the locking of gradiometric fluxonium qubits at the sweet spots (08/02/2022)
The KIT team in Germany, in collaboration with the Gran Sasso team in Italy and with help from collaborators in Canada and Romania, demonstrated that shielding from ionizing radiation improves the stability of gradiometric fluxonium qubits locking at the sweet spots. These results illustrate the violent effects of environmental ionizing radiation on superconducting quantum devices, and they further motivate efforts to abate ionizing impacts.

European Consortium to Develop Quantum Annealer under AVaQus
Kick-off meeting (14/10/2020)
AVaQus, the FET OPEN project on novel ideas for radically new technologies to develop annealing-based variational quantum processors, led by Dr. Pol Forn-Diaz from IFAE, on Wednesday October 14th, 2020.
The project launch took place virtually with a conference call between the 8 partner institutions.
AVaQus has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº 899561 to develop an integrated, small-size and fully-functional quantum processor that demonstrates coherent quantum annealing with 5 qubits fully connected in a multi-coupler network in the next 3 years.
