Query: Experimental Demonstration of Quantum Tunneling in IBM Quantum Computer   Quantum computers are the promising candidates for simulation of large
quantum systems, which is a daunting task to perform in a classical computer.
Here, we report the experimental realization of quantum tunneling of a single
particle through different types of potential barriers by performing digital
quantum simulations using IBM quantum computers. We consider two and
three-qubit systems to visualize the tunneling process and illustrate its
unique quantum nature. We observe the tunneling and oscillations of the
particles in a step-well, double-well, and multi-well potentials through our
experimental results. One may extend the proposed quantum circuits and
simulation techniques used here for observing the tunneling phenomena for
multi-particle systems in different potentials.
