One-dimensional(1D) array of Josephson junctions exhibit large and
universal response under microwave irradiation in the charge dominant
regime. As such the array is applied as an on-chip photon detector for
studying microwave emission from a biased 1D junction array. The
experiment indicates that Cooper-pair tunneling produces stronger
microwave than quasi-particle tunneling, making the array a good
emitter in superconducting state. Owing to the photon sending and
receiving mechanism mentioned above, correlated charge transport
between a pair of insulating arrays can be observed. The
current-current correlation appears in arrays separated by tens of
micrometers and the distance dependence of this correlation is
discussed. We foresee that such an photon-mediated correlation between
two distant quantum devices may find its application in remote
transferring classical and quantum information.
