Reduced Indium Tin Oxide as a Transparent Superconductor
Absorption of optical light in superconducting electronics is a major limitation on the quality of circuit architectures that integrate optical components with superconducting components. Such absorption causes losses in the optics and quasiparticle generation in the superconductor, decreasing the …
