## Description

- description: The tunability of superconducting magic-angle twisted-layer graphene
    films elevates this material system to a promising candidate for superconducting
    electronics. We implement a gate-tuned Josephson junction within a magic- angle
    twisted four-layer graphene film. Field-dependent measurements of the critical
    current show a Fraunhofer-like pattern that differs markedly from the standard
    pattern with characteristics typical for a weak transverse screener. We observe
    sudden shifts that we associate with vortices jumping into and out of the leads
    and present a quantitative analysis of this phenomenon. By tuning the leads to
    the edge of the superconducting dome, we observe fast switching between superconducting
    and normal states, an effect that we associate with thermally activated vortex
    dynamics. Time-dependent measurements of these switching phenomena provide us
    with the vortex energy scale of order Kelvin and an estimate for the London penetration
    depth of a few micrometers, in agreement with recent kinetic inductance measurements
    on twisted graphene films. Our results prove the utility of our junction as a
    sensor for vortex detection, allowing us to extract fundamental properties of
    the 2D superconductor.
