Topological Transitions in a Kerr Nonlinear Oscillator
A Kerr nonlinear oscillator (KNO) supports a pair of steady eigenstates, coherent states with
opposite phases, that are good for the encoding of continuous variable qubit basis states …

Quantum metric and metrology with parametrically-driven Tavis-Cummings models
We study the quantum metric in a driven Tavis-Cummings model, comprised of multiple
qubits interacting with a quantized photonic field. The parametrical driving of the photonic …
