What does quantum squeezing sound like?
👂Listen to a tone buried in “vacuum-like” noise getting squeezed!
🎧Headphones strongly recommended.

Improving capacitors in circuit QED is key to achieving longer-lived and scalable elements. Combined with mechanical functionality, vacuum-gap capacitors open new possibilities for hybrid quantum systems. Thanks to the editors for highlighting our work: journals.aps.org/prapplied/a…

High-kinetic inductance materials enable compact superinductors and nonlinear elements—but how reproducible are they? Can we measure the disorder? Is it low enough to build scalable multimode systems? Find out in our latest @NatureComms paper: nature.com/articles/s41467-0…

Great start to April with a new publication in @Nature_NPJ Quantum Information! In a simple SQUID array resonator, we demonstrate Landau-Zener transitions across the qubit, resonator, and multiphoton regimes. Take a closer look: nature.com/articles/s41534-0…

Excited to share our latest work is now published in @PRX_Quantum! We explore quantum sensing beyond linear scaling in superconducting circuits by leveraging critical phenomena. Check it out: journals.aps.org/prxquantum/…
Proud to share the details of the 'secret recipe' for our compact, low-loss vacuum-gap capacitors! Ideal for both optomechanics and circuit QED applications. Dive into it here: arxiv.org/abs/2501.03211

Collective quantum optomechanics now in @ScienceMagazine! 🚀 We prepared a collective mode of mechanical oscillators in its quantum ground state. A leap toward controlling many-body systems and probing quantum mechanics at the macroscopic scale! 👉 science.org/doi/10.1126/scie…
This work was done at @EPFL_en in Prof. Kippenberg's laboratory @LPQM_EPFL. I greatly appreciate the funding from @QSECenter_EPFL that funded my contribution.

🚀 Our new work on quantum sensing is out: arxiv.org/abs/2409.19968. We show how to go beyond linear scaling in superconducting circuits using critical phenomena. Exciting times for #QuantumMetrology 📏🔬 #Physics
Our latest publication is out today! We demonstrate a novel protocol to generate real mechanical excitations by modulating the ultrastrong vacuum of a coupled qubit-cavity system. Dive into the details here: scipost.org/SciPostPhys.17.1…

We have two fully-funded, 2-year postdoc positions open in my laboratory at Chalmers, one in spin sensing with ultralow-loss mechanical resonators and one on creating hybrid quantum systems of single atoms and optomechanical systems.
If you are interested in macroscopic quantum systems, in arxiv.org/abs/2407.02453 we ground state cool the bright collective mode of 6 mechanical resonators optomechanically coupled to a microwave cavity. We also show collective enhancement of optomechanical damping rate!
