摘要：

The macroscopic quantum tunneling rate out of the metastable state of a Josephson junction has been measured in a range of temperature where the quantum contribution is comparable with the thermal escape. From such measurements the traversal time of the barrier has been deduced and compared with the theoretical predictions of a semiclassical model.
