We devised a protocol that allows two parties, who may malfunction or
intentionally convey incorrect information in communication through a quantum
channel, to verify each other’s measurements and agree on each other’s results.
This has particular relevance in a modified version of the quantum coin
flipping game where the possibility of the players cheating is now removed.
Furthermore, the analysis is extended to $N$-parties communicating with each
other, where we propose multiple solutions for the verification of each
player’s measurement. The results in the $N$-party scenario could have
particular relevance for the implementation of future quantum networks, where
verification of quantum information is a necessity.
