One-dimensional parallel arrays of Josephson junctions are very interesting with respect to the rich dynamics inherent in this system. In quantum regime new physical phenomena are expected, which we aim to explore. The investigated system consists of several ultra-small Josephson junctions, which are arranged in parallel configuration forming an array of loops. We present preliminary measurements of such Josephson junction arrays, with novel I-V characteristics features.
