Behera · Prasanta K. Panigrahi Received: date / Accepted: date Abstract It is known that the traditional quantum secret sharing fails to achieve when there are rational participants, who as an individual can try to obtain the secret alone by maximizing his utilities. Therefore to overcome this problem, Rational Quantum Secret Sharing (RQSS) scheme is proposed by Qin et al. [Sci. Rep. 8, 11115 (2018)], where they introduce game theory to analyze the behavior of the participants, consequently preventing them from the deviation of the protocol. The scheme, being fair and robust, achieves the Nash equilibrium when it is performed faithfully. Here, we use IBM quantum experience beta platform to experimentally realize the above RQSS protocol by designing and implementing the quantum circuits on the real chips. We collect the experimental results with good fidelity and verify the performance of the protocol on the two five-qubit chips “ibmqx4” and “ibmqx2”.
