  We demonstrate the implementation of quantum cheque, proposed by Roy Moulick
and Panigrahi [Quantum Inf. Process (2016) 15: 2475], using the five-qubit IBM
quantum computer. Appropriate single qubit, CNOT and Fredkin gates have been
implemented for the realization of the quantum cheque transaction in a quantum
networked banking system. Quantum state tomography reveals the accuracy of the
implementation with comparable results from the theoretical and experimental
density matrices.
