Podsumowanie

Quantum integrated circuits (QICs) consisting of array of planar and ballistic Josephson junctions (JJs) based on In_0.75Ga_0.25As two-dimensional electron gas (2DEG) is demonstrated. Two different methods for fabrication of the two-dimensional (2D) JJs and QICs are discussed followed by the demonstration of quantum transport measurements in sub-Kelvin temperatures.
