1. A superconducting device, comprising:
two adjacent superconducting qubits disposed on a surface of a first substrate; and
a superconducting loop disposed between the two adjacent superconducting qubits and being inductively coupled to the two adjacent superconducting qubits, the superconducting loop including a hotspot nanowire that is biased by a bias current, the hotspot nanowire being in a superconducting state when the 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.
