Coherent versus stochastic error injection on a repetition-code logical qubit in superconducting hardware
S. L. M. van der Meer, M. Serra-Peralta, Y. Xin +5
The performance of quantum error correction (QEC) codes is limited by the underlying physical noise. Theoretical studies show that coherent and stochastic noise have different effe…
Wafer-scale uniformity of Dolan-bridge and bridgeless Manhattan-style Josephson junctions for superconducting quantum processors
N. Muthusubramanian, P. Duivestein, C. Zachariadis +7
We investigate die-level and wafer-scale uniformity of Dolan-bridge and bridgeless Manhattan Josephson junctions, using multiple substrates with and without through-silicon vias (T…
All-microwave leakage reduction units for quantum error correction with superconducting transmon qubits
J. F. Marques, H. Ali, B. M. Varbanov +9
Minimizing leakage from computational states is a challenge when using many-level systems like superconducting quantum circuits as qubits. We realize and extend the quantum-hardwar…
Post-fabrication frequency trimming of coplanar-waveguide resonators in circuit QED quantum processors
S. Vallés-Sanclemente, S. L. M. van der Meer, M. Finkel +9
We present the use of grounding airbridge arrays to trim the frequency of microwave coplanar-waveguide (CPW) resonators post fabrication. This method is compatible with the fabrica…
