Researchers from the Quantum Computing and Technologies (QCT) group at the Institut de Física d’Altes Energies (IFAE) have published a new result in Physical Review Letters reporting the direct observation of spontaneous photon down-conversion in a superconducting quantum circuit. The work demonstrates that a single microwave photon can decay into three lower-energy photons at a Josephson junction, revealing a new regime of light–matter interaction relevant for quantum optics and superconducting qubit technologies.

The IFAE spin-off ​​Qilimanjaro Quantum Tech, was recognized at the Mobile World Congress Barcelona 2024 as the best digital start-up in the world.

Researchers at the QCT group have achieved precise control over flux qubits, a crucial component for quantum annealing.

The Qilimanjaro-GMV joint venture has completed the first milestone in the construction of the quantum computer at BSC, which consists of remote access to a 5-qubit quantum chip. This chip is operational at Qilimanjaro’s Quantum Computing Technology laboratory at the Institut de Fisica d’Altes Energies (IFAE) and is, in fact, the first quantum computer located in Spanish territory.

“Cosmic muon flux attenuation methods for superconducting qubit experiments ” by members of the QCT group at IFAE has been uploaded to arXiv.

On Monday 3, May 2022 the TV program “El Cazador de cerebros” broadcasted in La2 of the Spanish National Television. The chapter focused on young students and had the title “Los Cerebros del Futuro”.

The QCT group at IFAE has observed the existence of the first superconducting flux qubit. This is a milestone for the group.These are the kind of chips that are of interest for quantum computing with quantum annealing, quantum optics and detection.
