Network-Based Quantum Computing: an efficient design framework for many-small-node distributed fault-tolerant quantum computing

Soshun Naito, Yasunari Suzuki, Yuuki Tokunaga

In fault-tolerant quantum computing, a large number of physical qubits are required to construct a single logical qubit, and a single quantum node may be able to hold only a small…
