ConScience and Quantum Technology Laboratory 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). #QuantumComputing

Researchers at Quantum Technology Laboratory Wallenberg Centre for Quantum Technology - WACQT 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.

New preprint out today with my postdoc Jorge Fernández-Pendás and the experimental group Quantum Technology Laboratory Chalmers University of Technology Wallenberg Centre for Quantum Technology - WACQT OpenSuperQPlus: ”Mitigation of frequency collisions in superconducting quantum processors”, arxiv.org/abs/2303.04663 (1/6)

Refrigerators are very useful. What about quantum refrigerators? Can they be useful? We built one Quantum Technology Laboratory that is! arxiv.org/abs/2305.16710 To our knowledge, this is the first demo of a practical quantum thermal machine.

Our work has now been published in Nano Letters: doi.org/10.1021/acs.na… Congrats to the great fab effort!

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

Enjoyed giving updates on scaling up superconducting QPU in multi-pronged approaches by various EU partners! Thanks Mikel Sanz and OpenSuperQPlus for organising this! cc. Jonas Bylander Quantum Technology Laboratory Wallenberg Centre for Quantum Technology - WACQT

New preprint out today with Trond Hjerpekjøn and Raphaël Van Laer, Wallenberg Centre for Quantum Technology - WACQT Chalmers University of Technology: ”Quantum resource states from heralded microwave-optical Bell pairs”. arxiv.org/abs/2308.14173

New experimental results out today with collaborators from Quantum Technology Laboratory! 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/2308.153… (1/7)
