  Quantum secret sharing is a way to share secret messages among the clients in
a group with complete security. For the first time, Hillery et al. (Phys Rev A
59:1829, 1999) proposed the quantum version of the classical secret sharing
protocol using GHZ states. Here, we implement the above quantum secret sharing
protocol in 'IBM Q 5 Tenerife' quantum processor and compare the experimentally
obtained results with the theoretically predicted ones. Further, a new quantum
binary voting protocol is proposed and implemented in the 14-qubit 'IBM Q 14
Melbourne' quantum processor. The results are analyzed through the technique of
quantum state tomography, and the fidelity of states is calculated for a
different number of executions made in the device.
