Direct Cultivation of Entangled Magic States
Gunsik Min, Jun Heo
Magic-state cultivation has largely targeted single-qubit non-Clifford resources. We show that the entangled state can be cultivated directly rather than…
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…
Defect-Adaptive Lattice Surgery on Irregular Boundary Surface-Code Patches
GunSik Min, Yujin Kang, Youshin Chung +1
Defect-adaptive surface-code methods construct valid logical patches on imperfect hardware, but fault-tolerant computation also requires certifying that requested logical operation…
Subspace-Confined QAOA with Generalized Dicke States for Multi-Channel Allocation in 5G CBRS Networks
Gunsik Min, Youngjin Seo, Jun Heo
Efficient spectrum sharing in the Citizens Broadband Radio Service (CBRS) band is essential for maximizing 5G network capacity, particularly when high-traffic base stations require…
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…
