Niobium-buffered tantalum for a superconducting fluxonium qubit

Niobium-buffered tantalum for a superconducting fluxonium qubit

We use a magnetron sputtering system to grow a tantalum film on a sapphire substrate with a niobium buffer layer at room temperature. The tantalum film is in α -phase, which is preferred for superconducting quantum devices. We fabricate a superconducting heavy fluxonium qubit with this niobium-buffe...
