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".

Even if the quantum computer has the power to tackle complex issues, however everyone would not be able to access it. So the client who has not obtained to quantum computers can ask for help to a quantum server, but the client does not trust the quantum server. In such type of situation, secure computation is required. The quantum server should not be able to know about the inputs and outputs of the quantum device and the task which the device is performing. This method of secure computation is called blind quantum computation (BQC). Here, we design a quantum circuit model for the generation of blind cluster states using IBM quantum experience. We propose a protocol for blind quantum computing of quantum Fourier transform (QFT) in four-qubit GHZ state and W state. The tomography plots and the fidelity of all the quantum circuits are found successfully.
