“…However, this number is still several orders of magnitude away from the requirement of quantum error correction, which is essential for general-purpose quantum computers. [4][5][6][7][8] To overcome this hurdle, networking small-size quantum processors that are cooled individually, i.e., distributed quantum computation, becomes an important avenue to a large-scale quantum computer. However, the superconducting qubits work in the microwave regime.…”
