We have several post-docs available in our group focusing on experimental quantum computing with superconducting qubits covering all areas of scaling our systems from coherence to control! The application deadline is April 30. @wacqt_sweden @chalmersuniv

New preprint just in time for the #APSMarch meeting: arxiv.org/abs/2403.00285
With @sandokokosen, @JonasBylander2, and the experimental team @wacqt_sweden @chalmersuniv @QTL_Chalmers (and @VTTFinland through @OpenSuperQPlus), we characterize crosstalk on our quantum processors.

New experimental results out today with collaborators from @QTL_Chalmers! We measure the long sought-after cubic phase state that is obtained by applying the cubic Hamiltonian x³ to an initial squeezed state, by engineering the cubic gate explicitly! scirate.com/arxiv/2308.15320 (1/7)

✨ #OpenSuperQPlus kick off meeting in progress❗
Over 85 project members & associates are gathering at @upvehu in Bilbao 🇪🇸 for some interesting lectures & group discussions within work packages & across topics. Today we also had a poster session.

Congrats to the great fab effort!
Now we also have trampolines in InGaP, with a Q>10^7, new work on the arxiv: arxiv.org/abs/2211.12469

Refrigerators are very useful. What about quantum refrigerators? Can they be useful? We built one @QTL_Chalmers that is!

To our knowledge, this is the first demo of a practical quantum thermal machine.

Researchers at @QTL_Chalmers @wacqt_sweden demonstrate a three-wave mixing, traveling-wave parametric amplifier with near-quantum-limited noise, 20 dB gain and 1 GHz 3-dB bandwidth between 4-8 GHz to detect signals at the few-photon level.

We have another successful PhD from the lab of professor @WitlefW! @sushonomics did a fantastic job today defending his work on developing a platform for investigating optomechanical couplings in III-V heterostructures!

ConScience and @QTL_Chalmers are working on scaled qubit production to 4-inch wafer to facilitate commercial adoption of quantum technologies.
Here we present our first successful 4-inch Qubit wafer (proprietary designs blurred).

We have yet another successful PhD from our group! Congratulations Martí and also Proffessor @WitlefW on your first PhD student! Martí worked extensively on magnetic levitation, developing several techniques to study quantum foundations. @wacqt_sweden @chalmersuniv
Our work developing TWPAs has received an editors pick! We demonstrate in this work 20dB of gain with a 3dB BW of 1GHz in three-wave mixing. By engineering a bandgap we suppress the generation and propagation of the 2nd harmonic and all higher harmonics
