Mitigation of interfacial dielectric loss in aluminum-on-silicon superconducting qubits
Janka Biznárová, Amr Osman, Emil Rehnman +9
We demonstrate aluminum-on-silicon planar transmon qubits with time-averaged energy relaxation times of up to , corresponding to Q = 5 million, and a highest obs…
Characterization and benchmarking of a phase-sensitive two-qubit gate using direct digital synthesis
Mats O. Tholén, Riccardo Borgani, Christian Križan +2
We implement an iSWAP gate with two transmon qubits using a flux-tunable coupler. Precise control of the relative phase of the qubit-control pulses and the parametric-coupler drive…
Experimentally verified, fast analytic and numerical design of superconducting resonators in flip-chip architectures
Hang-Xi Li, Daryoush Shiri, Sandoko Kosen +10
In superconducting quantum processors, the predictability of device parameters is of increasing importance as many labs scale up their systems to larger sizes in a 3D-integrated ar…
Mitigation of frequency collisions in superconducting quantum processors
Amr Osman, Jorge Fernàndez-Pendàs, Christopher Warren +6
The reproducibility of qubit parameters is a challenge for scaling up superconducting quantum processors. Signal crosstalk imposes constraints on the frequency separation between n…
