The theory of an elastic string trapped in a metastable state is developed in order to study the quantum creep of a single vortex line intrinsically pinned in a layered superconductor. Including Hall and dissipative dynamics, the crossover temperature separating thermal and quantum regimes is determined near to criticality and for small driving force. The decay rate is calculated in the overdamped and pure Hall limits: for overdamped systems conventional saturation is found at low-temperatures, whereas for pure Hall systems the rate vanishes following an Arrhenius law with a quantum-reduced activation energy. © 1995 The American Physical Society.
