The Floquet Fluxonium Molecule: Driving Down Dephasing in Coupled Superconducting Qubits
Matthew Thibodeau, Angela Kou, Bryan K. Clark
High-coherence qubits, which can store and manipulate quantum states for long times with low error rates, are necessary building blocks for quantum computers. Here we propose a dri…
