Last year, the researcher outlined the mathematical basis of a new quantum secure direct communication (QSDC) protocol. QSDC protocols are methods of information transfer which gain security from the use of quantum mechanical effects. Due to the measurement principle, quantum communication reveals eavesdroppers with a probability arbitrarily near unity. In a world where traditional encryption is increasingly threatened by quantum computers and Shor’s Algorithm, QSDC protocols provide impregnable security to banking transfers, diplomatic wires, and general communications. In contrast to existing QSDC protocols, the researcher’s protocol does not require the use of entanglement, which can be technically difficult to create and maintain without succumbing to decoherence and collapse. Further, the researcher’s protocol can be implemented with simple optical elements, transmits information directly, and retains quantum security advantages … Recently, IBM allowed the researcher to run trials on a real quantum computer, with a success rate above 90%. Given the promising results of the project, the protocol may soon be used to protect businesses, governments, and private citizens from certain types of monitoring, espionage, and cybercrime.
