The invention relates to an anti-
quantum computing intelligent household 
quantum cloud storage method and 
system based on a 
quantum key card. Each intelligent household 
assembly, the quantum communication service 
station and the security cloud are respectively provided with a quantum key card. A private key, an asymmetric key 
pool and a public key pointer random number are stored in each quantum key card, a third symmetric key 
pool is further stored in the mobile terminal, the home gateway and the quantum key card of the security cloud, and all the symmetric key pools are stored in the quantumkey cards of the quantum communication service 
station at the same time. When the smart home component and the security cloud communicate to access a file, the file signs and verifies the file by using quantum key cards of the two parties and adopting an asymmetric 
algorithm. When files are forwarded between the intelligent home component and the quantum communication service 
station and betweenthe quantum communication service station and the security cloud, a key is generated by utilizing a corresponding symmetric key 
pool, and encrypted communication is carried out by adopting a symmetricalgorithm.
