📢 Just published in Quantum!

No extra qubits? No problem.

We show how to prepare and manipulate nonclassical states just by shaking nonharmonic potential wells.

Many thanks to my collaborators—Hannes Pichler, Cindy Regal, and Oriol Romero-Isart!

📢 New arXiv preprint: What survives decoherence in phase-insensitive force sensing?
Squeezed Gaussian states lose their advantage fast, but Fock states are more robust. Number-squeezed cat states can be optimal under realistic controls.
