Superconducting Qubit with Tapered Junction Wiring

Authors

Optimal design of a superconducting transmon qubit with tapered wiring; Analytical formulas are presented for planar capacitors used in transmon design. Tapering of the wire connecting to the Josephson junction is shown to significantly lower its loss.

At Qolab, we are at the cutting edge of quantum computing, with a focus on developing superconducting qubits that are reliable, scalable, and capable of addressing real-world computational challenges.
