New arxiv preprint: Floquet-engineered enhancement of coherence times in a driven fluxonium qubit

In a collaboration with the Houck Lab, we use the quasienergy structure that emerges when a fluxonium superconducting circuit is driven periodically to encode quantum information with dynamically induced flux-insensitive sweet spots. The framework of Floquet theory provides an intuitive description of these high-coherence working points located away from the half-flux symmetry point of the […]
