摘要：
Measurements have been performed on superconducting flux qubits using a Josephson bifurcation amplifier (JBA). The qubit states are identified with the two stable dynamic states of a strongly driven non-linear oscillator that contains a SQUID sensor. Readout with high fidelity is achieved. Correlations in repeated measurements demonstrate that this readout is fully projective.
