摘要：

We present experimental and theoretical results showing that the distributed electromagnetic environment of a Josephson junction array can cause the junctions in the array to synchronize. Based on our experimental results and our distributed array model, we find that an external load is not necessary for junction synchronization. Also, we show that the high-frequency performance of an array can be significantly better than the performance of a single isolated junction. [S0163-1829(99)01034-6].
