This was a fun project and a great collaboration! Here we not only implement a new way to interconnect qubits. We also measure two mode squeezing in a calibration free manner (this was not possible in the microwave domain so far). Congrats to my PhD student Alejando Andrés-Juanes!

Excited to announce the launch of CIELO (“Cavity Integrated Electro Optics”), funded by the European Innovation Council Pathfinder Open under Horizon Europe. => Explore our research into measuring, converting & manipulating microwaves with light at www.cielo-horizon.eu

Happy to see our book "Why Nobody Understands Quantum Physics" published in English www.panmacmillan.com/authors/fran.... Unlike other popular science books, we explain quantum and its applications in the way working physicists use and understand them, without shying away from the many-body problem.

check out our latest proposal: ns timescale gates for qubits with measured bit-flip times of seconds to hours: arxiv.org/abs/2504.04807 (this is based on DC flux pulses - no RF required!)

In our latest result we show single-shot superconducting qubit readout via radio over fibre. => No microwave equipment in the fridge! Paper: www.nature.com/articles/s41... PR: ista.ac.at/en/news/when...

All-optical superconducting qubit readout - Nature Physics
Microwaves are usually used to interact with superconducting qubits, but optical photons can be processed at room temperature. The electro-optical transceiver presented here allows all-optical readout...
