摘要：
In this work, we have applied the entanglement concentration protocols to partially entangled subsets of classes of highly entangled multi-qubit states, created on IBM quantum computer. The highly entangled multi-qubit states like Z-states and cluster states act as a powerful resource in measurement based computation model. The success of the protocol is analysed through calculating the success probability obtained from the IBM quantum computer and simulator with which the protocol can generate maximally entangled states. The results of the protocol obtained from the IBM simulator are in close agreement with the theoretical predictions of the protocol, however, the results of IBMQ computer show comparative deviations due to large amount of gate errors, qubit errors and readout errors.
