We report superconducting fluxonium qubits with coherence times largely limited by energy relaxation and reproducibly satisfying T2 > 100 microseconds (T2 > 300 microseconds in one…
Protecting a superconducting qubit from energy decay by selection rule engineering
Yen-Hsiang Lin, Long B. Nguyen, Nicholas Grabon +3
Quantum control of atomic systems is largely enabled by the rich structure of selection rules in the spectra of most real atoms. Their macroscopic superconducting counterparts have…
