Extremely happy with this collaboration, that started with the EU project Superqulan and culminated with a very nice demonstration of photon mode multiplexing in quantum links, led by @andreasateth.bsky.social's group at ETHZ

First time!
Special luggage.
Where am I going and what for?
Also will Swiss and Air Canada manage to loose my gear again?
Great start for #Switzerland 🇨🇭 into the #Olympics !
Reaching 150 km/h is challenging. You probably fall at lower speeds than that and then slow down significantly.
I doubt it.
EM&J
Up for a race?
I hear top speed is 150 km/h if you know what you are doing!
What about a warm-up drink?
Update!
Gooooood moooorrrrnnnning from … Mönch, und Jungfrau.
Doing some skiing today.
Maybe participating in the Slalom race spontaneously.
Where am I?
Goooooood moooorrrrning.
Do you recognize this place?
Any guesses on what I am here for?
Bon appetit.
More food pics from my holiday cooking adventures.

Got back to doing some cooking over the holidays!
These are meat balls with a spicy tomato-pepperoni-ginger sauce which turned out very nice.
I have not posted any food pics in a while!
Are you still into it?
We do not have a special name as far as I can tell. I will ask and let you know.

... control the qubit transition frequency on time scales ranging from nano- to microseconds.
Also make sure that there are no bias-tees in your circuit that have a non-linearity, observable as a power-dependence of the response function, which may hamper your efforts.

Do you find it challenging to accurately control the transition frequency of your superconducting #qubit by applying magnetic flux? Frequently, the frequency dependence of the response function of the electronics, the wiring, and the flux-bias circuitry must be compensated for to accurately ..

Five years ago at the @qudev Lab of ETH Zürich we have reported on the first realization of a "Microwave #Quantum Link between Superconducting Circuits Housed in Spatially Separated Cryogenic Systems" coupling #qubits across a distance of 5 meters through a #microwave waveguide.
