Quantum Communication 101 with NASA Handbook

Researchers have made significant progress in developing quantum cryptography with classical communication, enabling secure copy-protection, verification, and more. This breakthrough builds upon previous work on universal blind quantum computation by Anne Broadbent, Joseph Fitzsimons, and Elham Kashefi. The new approach uses parallel remote state preparation, a technique that allows for the secure distribution of encrypted data. This innovation has far-reaching implications for secure communication and data protection.

Key players in this field include Andrei Gheorghiu, Thomas Metger, and Alexander Poremba, who have made significant contributions to the development of quantum cryptography. Other notable researchers in this area include Deutsch, Jozsa, Grover, and Barz, who have worked on rapid solution of problems by quantum computation, quantum mechanics, and blind quantum computing.

Organizations like NASA are also involved in this research, with projects focused on advancing quantum technologies. The work has the potential to revolutionize secure communication, enabling unconditional verification and robustness in quantum computing.
