Authentication using key distribution through segmented quantum computing environments

A system comprising:

• one or more classical processors;
• and
• quantum computing hardware;
• wherein the system is configured to perform operations comprising:
• receiving i) a first plaintext data input from a first party, and ii) a second plaintext data input from a second party;
• applying a quantum computation translation operation to i) the first plaintext data input to generate a corresponding first sequence of quantum computations, and ii) the second plaintext data input to generate a corresponding second sequence of quantum computations;
• implementing i) the first sequence of quantum computations in a first segmented quantum computing environment to obtain a first sequence of measurement results, and ii) the second sequence of quantum computations in a second segmented quantum computing environment to obtain a second sequence of measurement results;
• generating i) a first encryption key using the first sequence of measurement results, ii) a second encryption key using the second sequence of measurement results, and iii) an encrypted authorization token using the second encryption key;
• and
• sending i) the first encryption key to the first party, and ii) the encrypted authorization token to the second party.
