Query: Driving forbidden transitions in the fluxonium artificial atom   Atomic systems display a rich variety of quantum dynamics due to the
different possible symmetries obeyed by the atoms. These symmetries result in
selection rules that have been essential for the quantum control of atomic
systems. Superconducting artificial atoms are mainly governed by parity
symmetry. Its corresponding selection rule limits the types of quantum systems
that can be built using electromagnetic circuits at their optimal coherence
operation points ("sweet spots"). Here, we use third-order nonlinear coupling
between the artificial atom and its readout resonator to drive transitions
forbidden by the parity selection rule for linear coupling to microwave
radiation. A Lambda-type system emerges from these newly accessible
transitions, implemented here in the fluxonium artificial atom coupled to its
"antenna" resonator. We demonstrate coherent manipulation of the fluxonium
artificial atom at its sweet spot by stimulated Raman transitions. This type of
transition enables the creation of new quantum operations, such as the control
and readout of physically protected artificial atoms.
