Autonomous Quantum Error Correction of Spin-Oscillator Hybrid Qubits
Sungjoo Cho, Ju-yeon Gyhm, Hyukjoon Kwon +1
We propose a novel measurement-free scheme for stabilizing a spin-oscillator hybrid qubit via autonomous quantum error correction. The engineered Lindbladian renders the code space…

Code-agnostic bosonic noise suppression with hybrid rotations
Saurabh U. Shringarpure, Siheon Park, Sungjoo Cho +4
Physical-level noise on traveling bosonic modes remains a critical bottleneck for scalable quantum information processing. We show that for any single-mode bosonic code (qumode) co…
