Tunneling qubit operation on a protected Josephson junction array
Tunneling qubit operation on a protected Josephson junction array
We propose a complete quantum computation process on a topologically protected Josephson junction array system, originally proposed by Ioffe and Feigel'man [Phys. Rev. B 66, 224503 (2002)]. Logical qubits for computation are encoded in the punctured array. The number of qubits is determined by the number of holes. The topological …
