A single shared Π-filter integrated in the feedline uses engineered microwave interference to suppress environmental admittance and deliver Purcell-limited qubit relaxation times above 1 ms across roughly 1.5 GHz while preserving readout and reset modes.
io-HEOM accurately captures non-Markovian waveguide QED arising from spatially non-local coupling and non-linear dispersion in different spectral densities.
