Improved error correction with leakage reduction units built into qubit measurement in a superconducting quantum processor
Yuejie Xin, Sean L. M. van der Meer, Marc Serra-Peralta +5
Leakage to non-computational states is a source of correlated errors in both time and space that limits the effectiveness of quantum error correction (QEC) with superconducting cir…

Optimizing the frequency positioning of tunable couplers in a circuit QED processor to mitigate spectator effects on quantum operations
S. Vallés-Sanclemente, T. H. F. Vroomans, T. R. van Abswoude +8
We experimentally optimize the frequency of flux-tunable couplers in a superconducting quantum processor to minimize the impact of spectator transmons during quantum operations (si…
