The Flux Qubit Revisited to Enhance Coherence and Reproducibility
F. Yan, S. Gustavsson, A. Kamal +11
The scalable application of quantum information science will stand on reproducible and controllable high-coherence quantum bits (qubits). Here, we revisit the design and fabricatio…

Thermal and Residual Excited-State Population in a 3D Transmon Qubit
X. Y. Jin, A. Kamal, A. P. Sears +9
We present a systematic study of the first excited-state population in a 3D transmon qubit mounted in a dilution refrigerator with a variable temperature. Using a modified version…

Coherence and Decay of Higher Energy Levels of a Superconducting Transmon Qubit
Michael J. Peterer, Samuel J. Bader, Xiaoyue Jin +7
We present measurements of coherence and successive decay dynamics of higher energy levels of a superconducting transmon qubit. By applying consecutive -pulses for each sequenti…
