Long-range data transmission in a fault-tolerant quantum bus architecture
Abstract We propose a fault-tolerant scheme for generating long-range entanglement at the ends of a rectangular array of qubits of length R with a square cross-section of $$m=O({\log }^{2}R)$$ m = O ( log 2 R ) qubits. It is realized by a constant-depth circuit producing a constant-fidelity Bell-pai...
