We have characterized devices fabricated on different substrates, used several methods to deposit the Al and Nb films, and explored various surface cleaning techniques to remove the native silicon oxide immediately prior to cooling the resonators. Your exact time may vary depending on wind speeds. It also adds an extra 30 minutes for take-off and landing. This assumes an average flight speed for a commercial airliner of 500 mph, which is equivalent to 805 km/h or 434 knots. Las Vegas, Nevada time is 0 hours ahead of PST. The total flight duration from Wisconsin to Nevada is 3 hours, 27 minutes. and done PST stands for Pacific Standard Time. Simply mouse over the colored hour-tiles and glance at the hours selected by the column. ![]() We have also implemented novel resonator designs, including tapered resonators to study the relative contributions to loss from TLS and quasiparticles, and resonators with flux pinning structures to suppress the loss contribution from trapped flux. This time zone converter lets you visually and very quickly convert PST to Las Vegas, Nevada time and vice-versa. This allows us to extract the contribution to loss from interfacial TLS defects. In this work, we measure Q i as a function of photon occupation in Al and Nb thin-film microwave resonators with different center conductor and gap widths. However, in real devices, Q i is limited by the presence of various loss channels, including two-level state (TLS) defects at amorphous interfaces, trapped magnetic flux vortices, and nonequilibrium quasiparticles. ![]() Ideally, the internal quality factors Q i of these resonators should reach ten million or higher, limited only by the loss tangent of the silicon or sapphire substrate. At the same time, these resonators are a versatile testbed for characterizing the various contributions to qubit loss. Superconducting coplanar waveguide resonators play a critical role in information storage and qubit state measurement in superconducting quantum information processing.
