Abstract As quantum coherence times of superconducting circuits have increased from nanoseconds to hundreds microseconds, they are currently one the leading platforms for information processing. However, needs further improve by orders magnitude reduce prohibitive hardware overhead current error correction schemes. Reaching this goal hinges on reducing density broken Cooper pairs, so-called quasiparticles. Here, we show that environmental radioactivity is a significant source nonequilibrium...
Out of equilibrium quasiparticles (QPs) are one the main sources decoherence in superconducting quantum circuits and that is particularly detrimental devices with high kinetic inductance, such as impedance resonators, qubits, detectors. Despite significant progress understanding QP dynamics, pinpointing their origin decreasing density remain outstanding tasks. The cyclic process recombination generation QPs implies exchange phonons between thin film underlying substrate. Reducing number...
In BCS superconductors, the superfluid stiffness is virtually constant at low temperature and only slightly affected by exponentially density of thermal quasiparticles. Here, we present an experimental theoretical study on dependence $\Theta\left(T\right)$ in a strongly disordered pseudo-gaped superconductor, amorphous $\text{InO}_{x}$, which exhibits non-BCS behavior. Experimentally, report unusual power-law suppression $\delta\Theta\left(T\right)\propto T^{b}$ $T\ll T_{c}$, with...
