Résumé
A dynamically protected cat-qubit is an open quantum system that stabilizes a two-dimensional subspace (called code space) of a quantum harmonic oscillator and shows very promising robustness to noise. Experimental realizations of cat-qubits rely on reservoir engineering, a method of coupling a high-quality cavity with a dissipative cavity. In this talk, after an introduction to the mathematics of open quantum systems, we will present a new generalized LaSalle invariance principle to prove the long-time convergence of a cat-qubit to the code space.
