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…

Improving Entanglement Resilience in Quantum Memories with Error-Detection-Based Distillation
Huidan Zheng, Gunsik Min, Ilkwon Sohn +1
The degradation of entanglement in quantum memories due to decoherence is a critical challenge for scalable quantum networks. We present an entanglement distillation protocol based…
