Case study highlights
Superconducting Qubits Case Study
- Delft, The Netherlands
- ImpaQt Consortium
- Quantum Computing
We successfully measured and characterized working transmon qubits with lifetimes up to 15 µs. Showing that Cri/oFlex® 2X is well suited for transmon qubits and can drastically reduce installation time due to their compact size, flexibility, and integrated filters.
