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.

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

Overheard at march meeting: "...they definitely don't have majoranas..."

I'm hiring at the Junior (master in quantum) and mid-senior (PhD) level. If you are interested or know someone who might be, check out the job adds below! jobs.lever.co/alice-bob/9db2… jobs.lever.co/alice-bob/e7be…

.@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

Arg @jimcramer just tanked my company

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

Nothing like the smell of a freshly refurbished VNA.

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/10.1063/5.0218…). This type of coupling offers an additional tuning knob independent of the capacitance matrix!

@JWO_Garmon Ah, pre-etched makes a lot more sense. I read it as they will send you a little etch-it-yourself kit.

@KrayzmanLev With a pre-etched option as well! quantummicrowave.com/product/3d-tra…

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

@roydherbert @ParthJatakia Thought about it! Then got too lazy...

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.

@abe_asfaw @mattjmcewen May I still choose to hide under a mountain and have my subterranean evil scientist lair?

For the record I tried to convince @mattjmcewen to add to the abstract: “on the question of hiding meters under mountains or carefully engineer micromountains, we affirmatively demonstrate that the latter achieves the desired results”

While hiding under mountains may not be needed, carefully engineering our topography looks like a near-certain necessity
