A Folded Surface Code Architecture for 2D Quantum Hardware
Zhu Sun, Zhenyu Cai
Qubit shuttling has become an indispensable ingredient for scaling leading quantum computing platforms, including semiconductor spin, neutral-atom, and trapped-ion qubits, enabling…

Fault-tolerant Quantum Computation without Distillation on a 2D Device
Thomas R. Scruby, Kae Nemoto, Zhenyu Cai
We show how looped pipeline architectures - which use short-range shuttling of physical qubits to achieve a finite amount of non-local connectivity - can be used to efficiently imp…
