Asymmetry-aided measurement-based quantum repeaters and distributed quantum computing with a decoder-free client
Wooyeong Song, Sungyeon Kook, Wonhyuk Lee +1
Distributed quantum computation needs to move logical qubits across lossy optical links, yet this transmission layer is usually designed separately from the computation it serves.…

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…
