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…
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…
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…
