Quantum interference in a three level Λ-type system can result in non-linear optical effects such as electromagnetically induced transparency, slow, and fast light. We have designed a Λ system by engineering the coupling and decay rates of an Al/AlOx/Al transmon qubit (T1 =4 us) dispersively …

Abstract: In December 1972 the final Apollo mission to the Moon, Apollo 17, spent three days exploring the 2 kilometer deep Taurus-Littrow Valley. During their time on the lunar surface, Commander Gene Cernan and Lunar Module Pilot Harrison “Jack” Schmitt sampled over 10 stations on the surface, including …
