Abstract：To leverage measurement-based quantumcomputationandquantum network coding fordistributing entangled particles andtransmitingquantum informationbetweenremote nodes inthe buterflynetwork，this paperproposedameasurementbased quantum network coding scheme on two-dimensional clusterstates.The proposed schemefrstlydesigneda measurementbasedquantumrelay protocol.Then，byconstructing a graph state model that matchedthe buterflynetwork topologyand designing corresponding measurement strategies，itenabledparalelquantumoperationsbetweenremote nodes.Inadition， buildinguponexistingwork，itprovidedanin-depththeoreticalderivationof themeasurementprocessandquantumstateevo lution，therebydemonstrating thefeasibilityandcorectnessoftheproposedschemefromatheoreticalperspective.This schemenotonlyefectivelyovercametheimpactof photonloss inlong-distanceentanglementdistributionbutalsosignificantly enhanced the eficiencyandflexibilityofquantum communication，enabling eficientandreliablequantum communication in thebutterflynetwork.Securityanalysisandperformancecomparisonsshowthattheproposedschemecanefectivelyresisttypicalatack modelssuchasquantumeavesdropping.Anditachieves significant improvementsinbothresourceconsumptionand operational complexity，demonstrating superior overall performance.
