Abstract
Systems, apparatuses, methods, and computer program products are disclosed for classical-quantum encryption and decryption. An example method for classical-quantum encryption includes receiving, by communications hardware, a symmetric key and a plaintext message, generating, by a function generator, an analytic function using the symmetric key and the plaintext message, computing, by a cryptography unit, a ciphertext based on a Taylor series expansion of the analytic function, and outputting the ciphertext. An example method for classical-quantum decryption, the method includes receiving, by communications hardware, a symmetric key and a ciphertext, deriving, by a cryptography unit and using a quantum computer, an analytic function using the ciphertext, generating, by a function generator, a plaintext message using the analytic function and the symmetric key, and outputting the plaintext message.
