Original Abstract Submitted

a first superconducting device includes two first adjacent superconducting qubits and a superconducting loop disposed between and inductively coupled to the two first adjacent superconducting qubits. the superconducting loop includes a first hotspot nanowire that is in a superconducting state when a bias current is less than a critical current and in a high resistive state when the bias current is not less than the critical current. a second superconducting device includes two second adjacent superconducting qubits and a superconducting lead extending from one superconducting qubit to the other and being capacitively coupled to the two second adjacent superconducting qubits. the superconducting lead includes a second hotspot nanowire that is in a superconducting state when a bias current is less than a critical current and in a high resistive state when the bias current is not less than the critical current.
