Mohammad Ansari: The Kondo effect

Mohammad Ansari, Institute for Quantum Computing

Abstract

With lowering temperature, a qubit may become strongly coupled to the reservoirs. This can result into some exotic situations such as: the appearance of full conductivity instead of current blockade in a quantum dot, increasing resistivity with lowering temperature in a metal, and the appearance of microresonators in the critical current noise in a Josephson junction. In this talk, some of these phenomena are discussed.
