Entanglement is a key resource in the field of quantum computation and quantum technologies. One has to deal with measurement error-mitigation in the present day Noisy Intermediate-scale Quantum (NISQ) processors so as to witness advantages offered by entanglement. In this paper we implement Bell state measurements in IBM open access 7-qubit quantum processor ibmq_nairobi and mitigate errors incurred. We evaluate fidelities of all four Bell states (theoretical) with the ones retrieved experimentally before and after measurement error-mitigation. Our results reveal a clear enhancement in quantum fidelity after error-mitigation methods are employed.
