Finally on the arxiv, our most recent work with Chan U, @GanjamSuhas, and @JTeohQuantum: arxiv.org/abs/2402.09504! We demonstrate a new design for a bosonic superconducting quantum memory: the suspended coaxial resonator.

When I moved from a physics to an EE department, I stopped getting spam from Einstein-was-wrong types, and started getting predatory journals/conferences and requests to work in my lab. Now that I've left academia, I get much less spam total. I kind of miss that first kind though

Now that the year of quantum is over, we can return to our regularly-scheduled classical.

I should not have to spend this much time figuring out how the roman date system works to be able to read when my diploma was awarded.

Our paper that tells you how to make millisecond transmons just appeared. Congrats, Matthew, Faranak and team! In collaboration with Nathalie de Leon and Bob Cava, and building on five years of work in @C2QAdvantage arxiv.org/abs/2503.14798

.@Yale_QI and @BrookhavenLab researchers built a compact device that stored #quantum information for more than one millisecond! The design of this device was informed by their new systematic approach to understanding how energy is lost from #qubits. 🔗: bit.ly/4hA71Tm

Nothing like the smell of a freshly refurbished VNA.

(It doesn't actually smell like anything. The smell is metaphorical.)

I am excited to share that I will be joining the ECE Department at the University of Illinois Chicago (UIC) as an Assistant Professor. I am actively recruiting motivated students to join my research group starting in Spring 2025.

In the protected qubits world, the long-awaited protomon demonstration is finally available: arxiv.org/abs/2411.16648 by @iamshashwatk, @XinyuanYou_Q & Xanthe et al. Neat experiment with many subtleties; raises interesting questions about loss modelling in superconducting qubits.

Today, we published our work on the pure kinetic inductance coupling between generalized flux qubits and their readout modes (doi.org/10.1063/5.0218361). This type of coupling offers an additional tuning knob independent of the capacitance matrix!

You can apparently buy a 5N Al rectangular cavity from one of the common hardware manufacturers/distributers. What a world.

Since the field is concentrated in the centre conductor, we are less sensitive to the package quality. We achieve millisecond coherences, on par with stub cavities, in devices where the package is made of 6061 aluminium alloy. The different parts can be replaced separately.
