Pair tunneling to a two-dimensional superconductor is reported for the first time. It is found that flux quantization disappears due to the nature of the two-dimensional superconductor, while the magnitude of the pair tunneling current is unaffected. Also due to the specific behavior of the system under consideration, a crossover to conventional three-dimensional behavior is observed at low temperatures.
