Quantum information can be copied as many times as needed provided it is encrypted, for secure, redundant quantum cloud storage

"information stored in qubits through delicate entanglement, where observing/ interacting with stored information changes state, making copying impossible... overcome by encrypting information during copying process, where even needing to use 1-time decryption key enables redundant, scalable encrypted quantum cloud services... encryption/ single-use keys make backups inherently secure... quantum cloud storage for: medicine, materials science, cryptography"
