Protected Fluxonium Control with Sub-harmonic Parametric Driving
Protected Fluxonium Control with Sub-harmonic Parametric Driving
Protecting qubits from environmental noise while maintaining strong coupling for fast high-fidelity control is a central challenge for quantum information processing. Here, we demonstrate a novel control scheme for superconducting fluxonium qubits that eliminates qubit decay through the control channel by reducing the environmental density of states at the transition …
