Three-Dimensional Niobium Coaxial Cavity with second Lifetime
Takaaki Takenaka, Takayuki Kubo, Imran Mahboob +4
We report on the internal quality factor of a three-dimensional niobium quarter-wave coaxial cavity, with mid-temperature annealing, exhibiting at…
Efficient spectrum analysis for multi-junction superconducting circuit
A. Tomonaga, H. Mukai, K. Mizuno +1
The extraction of transition frequencies from a spectrum has conventionally relied on empirical methods, and particularly in complex systems, it is a time-consuming and cumbersome…
Residual--coupling suppression and fast two-qubit gate for Kerr-cat qubits based on level-degeneracy engineering
Takaaki Aoki, Akiyoshi Tomonaga, Kosuke Mizuno +1
Building large-scale quantum computers requires an interqubit-coupling scheme with a high on-off ratio to avoid unwanted crosstalk coming from residual coupling and to enable fast…
Effect of Decoherence for Gate Operations on a Superconducting Bosonic Qubit
Kosuke Mizuno, Takaaki Takenaka, Imran Mahboob +1
High-quality-factor 3D cavities in superconducting circuits are ideal candidates for bosonic logical qubits as their fidelity is limited only by the low photon loss rate. However,…
