📢 Just published in Quantum!
quantum-journal.org/papers/q-202...
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.
