Fault-tolerant Fusion-based Quantum Computing with the Four-legged Cat Code
Harshvardhan K. Babla, James D. Teoh, Jahan Claes +4
The four-legged cat code is a quantum error-correcting code designed to address the predominant error in bosonic modes: single-photon loss. It was the first such code to surpass th…

Characterization of drive-induced unwanted state transitions in superconducting circuits
W. Dai, S. Hazra, D. K. Weiss +11
Microwave drives are essential for implementing control and readout operations in superconducting quantum circuits. However, increasing the drive strength eventually leads to unwan…
