Quantum Computing with Superconducting Electronics
Abstract
An implementation of a quantum computer using superconducting electronics has been proposed and studied. A single Josephson junction superconducting quantum interference device (SQUID) may serve as a suitable two-state quantum system to be used as the qubits of a possible quantum computer. The quantum states of the superconducting qubits may be manipulated by single flux quantum pulses created and controlled by other "on-chip" superconducting circuitry. Gates to allow logical interactions of qubits have also been conceptualized. The parameters of the qubit SQUIDs and other associated circuitry were found to be within current technological constraints and a first experiment to demonstrate quantum coherence in a superconducting qubit was designed.
