Encryption system and method for quantum annealers

An encryption method for secure communication between devices during quantum annealing or QUBO-based routines, which are executed on a quantum device with configurations determined or supported by at least one classical computing device, wherein the encryption and decryption of data are managed by the classical computing device,

• wherein, within a QUBO based routine that includes set of pre-trained weak learners that provide output for test values and weight adjustment process for these weak learners and after the discretized to model it as a QUBO;
• to encrypt the weights of the weak learners, at least one of bellow step or combination more than one with storing combination order in at least one storage medium;
• using different encoding depths for different weights with the assigning the weights according to the correlation in between the weak learners with the registration of this encoding information;
• shuffling the order of the variables randomly with the registering this order information;
• and
• converting the QUBO matrix, which is stored in at least one storage medium and generating a string which includes two different number whose length matches the solution space dimensionality and registering the strings with spin flipping these numbers;
• and
• to decrypt the data which is received from at least one quantum device with encrypted by classical computing device before the transfer procedure using encoding information, order information, spin flipped result, combination order information or suitable combination of them according to the encryption.
