An Entanglement-Assisted Stabilizer Framework for Distributed Sensing of Local Phases
Huidan Zheng, Ilkwon Sohn, Jun Heo
Distributed quantum sensing requires spatially separated probes to acquire local parameters while maintaining compatibility with network-level quantum information processing. We de…

Low Spatial Cost CCZ Magic State Factory
Sungyeon Kook, Yujin Kang, Ilkwon Sohn +1
We propose a design framework for reconstructing gate-based magic state distillation protocols as compact joint-measurement architectures implementable with the surface code. The g…

3D Stacked Surface-Code Architecture for Measurement-Free Fault-Tolerant Quantum Error Correction
GunSik Min, IlKwon Sohn, Jun Heo
Mid-circuit measurements are a major bottleneck for superconducting quantum processors because they are slower and noisier than gates. Measurement-free quantum error correction (mf…
