Qubit ZooAbstractThe superconducting transmon qubit is a leading platform for quantum computing and quantum science.
Key Results
- Building large, useful quantum systems based on transmon qubits will require significant improvements in qubit relaxation and coherence times, which are orders of magnitude shorter than limits imposed by bulk properties of the constituent materials.
- This indicates that relaxation likely originates from uncontrolled surfaces, interfaces, and contaminants.
- Previous efforts to improve qubit lifetimes have focused primarily on designs that minimize contributions from surfaces.
