  Blockchain is a decentralized system that allows transaction transmission and
storage according to the roles of the Consensus algorithm and Smart contracts.
Non-fungible tokens (NFTs) consolidate the best characteristics of blockchain
technology to deliver unique and bona fide tokens, each with distinctive
attributes with non-fungible resources. Unfortunately, current classical NFTs
are suffering from high costs regarding the consumed power of mining and lack
of security. Therefore, this paper presents a new protocol for preparing
quantum non-fungible tokens where a quantum state representing NFT is mounted
on a blockchain instead of physically giving it to the owner. The proposed
scheme is simulated and analyzed against various attacks and proves its ability
to secure against them. Furthermore, the presented protocol provides reliable
and cheaper NFTs than the classical one.
