Quasiparticle effects in transmons with gap-asymmetric junctions
Seminar featuring Giampiero Marchegiani - Technology Innovation Institute, Abu Dhabi
Single-particle excitations, known as Bogoliubov quasiparticles, threaten the operation of superconducting qubits. In this presentation, we theoretically revisit and generalize the qubit-quasiparticle interaction, including the gap asymmetry in Josephson junctions, which naturally arises from the deposition of aluminum layers with different thicknesses. ...
