SECURE MULTI-STATE QUANTUM KEY DISTRIBUTION WITH WAVELENGTH DIVISION MULTIPLEXING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240048372 titled 'SECURE MULTI-STATE QUANTUM KEY DISTRIBUTION WITH WAVELENGTH DIVISION MULTIPLEXING
Simplified Explanation
The abstract of this patent application describes a system and method for quantum key distribution using wavelength division multiplexing and encoding information using both wavelength and polarization of photons. The system allows for the representation of ternary-coded digits, quaternary-coded digits, and higher-radix digits using single photons. The information expressed in a lower radix can be encoded in a higher radix and combined with a string of key values to produce a datastream with all allowed digit values of that radix. This enables the detection of eavesdropping without the need for the sender and receiver to exchange additional information after transmission.

Original Abstract Submitted
the performance of quantum key distribution by systems and methods that use wavelength division multiplexing and encode information using both wavelength and polarization of photons of two or more wavelengths. multi-wavelength polarization state encoding schemes allow ternary-coded digits, quaternary-coded digits and higher-radix digits to be represented by single photons. information expressed in a first radix can be encoded in a higher radix and combined with a string of key values to produce a datastream having all allowed digit values of that radix in a manner that allows eavesdropping to be detected without requiring the sender and receiver to exchange additional information after transmission of the information.
