The SupraFab PDK consists of Al-AlO-Al Manhattan Josephson junctions with a Niobium layer and can be used to make qubits and other superconducting circuits. It can be used for research and prototyping purposes.
Features
- Al-Al-ALOx-AL Manhattan junctions (30-x-60 nm) thickness
- Current density around 2uA/um2,
- Sapphire substrate
- Nb layer 100 nm with a 4 ohm/square resistivity and a 0.6 pH/square kinetic inductance
- Resonators with Q-factor of approx. 1 million
- T1 and T2 of qubits from test runs of 35 us.
- 5x5 mm design space
