Millisecond coherence reached for fluxonium qubit

"increase relaxation time to over 1.43 ms, 10X during which qubit moves between states and during which data stored can be used,,, reduced operating frequency optimizing circuit parameters, increase coherence time of qubit, bringing nearly to that of transmons, marking them as a possible alternative... more tweaking could lead to even longer coherence times, possibly making fluxonium a better choice for use in future quantum circuit research efforts
