Quantum Technology Laboratory (QTL) Headed by professors Per Delsing and @JonasBylander2. Developing technologies in #quantumcomputing w/ #superconductingqubits

[Quantum Technology Laboratory @QTL_Chalmers]

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: https://t.co/ymjRgiB3io

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! https://t.co/PgxCFUvyjd (1/7)

New preprint out today with @trondhjerpekjon and @RaphaelVanLaer, @wacqt_sweden @chalmersuniv: ”Quantum resource states from heralded microwave-optical Bell pairs”. https://t.co/TJlIZEVRTS

[OpenSuperQPlus @OpenSuperQPlus]

✨ #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!

[Aamir Ali @ZackusM]

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.

New preprint out today with my postdoc Jorge Fernández-Pendás and the experimental group @QTL_Chalmers @chalmersuniv @wacqt_sweden @OpenSuperQPlus: ”Mitigation of frequency collisions in superconducting quantum processors”, https://t.co/6v2yefDFv1 (1/6)

[Applied Physics Letters @AppliedPhysLett]

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.

[Quantum Technology Laboratory @QTL_Chalmers]

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 @ConScienceAB]

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).

[Quantum Technology Laboratory @QTL_Chalmers]

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

[Quantum Technology Laboratory @QTL_Chalmers]

Great job Anita and everyone @chalmersuniv @wacqt_sweden !

[Quantum Technology Laboratory @QTL_Chalmers]

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
