Direct Cultivation of Entangled Magic States
Gunsik Min, Jun Heo
Magic-state cultivation has so far focused mainly on single-qubit non-Clifford resources. We develop a direct cultivation architecture for the entangled state $|CS\rangle=CS|++\ran…
Coded Clifford Measurements for Multiqubit Magic-State Cultivation
Gunsik Min, Jun Heo
Magic-state cultivation suppresses errors by measuring logical Clifford checks and discarding inconsistent outcomes. For an entangled resource, several measurement branches are usa…
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…
Defect-Adaptive Lattice Surgery on Irregular Boundary Surface-Code Patches
GunSik Min, Yujin Kang, Jun Heo
Defect-adaptive surface-code methods have substantially advanced the construction of valid logical patches on imperfect hardware, but fault-tolerant computation also requires execu…
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…
