Invention:
This technology is a method for secure, high speed quantum communication that uses ultrafast squeezed light. This ultrafast squeezed light Is generated by directing quantum light generated by a light field synthesizer (LFS) onto a silicon dioxide target. This light, which is generated at a petahertz-scale frequency, is used for quantum communication by encoding information into its waveforms. The squeezed light is transmitted to a receiver, and characteristics of the light crucial to decoding are communicated separately to decoders at the receiver. If the squeezed light is intercepted as it travels to a receiver, that interception would alter the squeezing degree of the light, revealing the attempted security breach to both the transmitter and the receiver and thwarting it. Furthermore, in order to decode intercepted light, knowledge of the intensity threshold and, of course, of the decoding key, would be necessary. These factors make for a highly secure ultrafast quantum communications system.
Background:
As many industries become more and more data-driven, and as awareness of cybersecurity risk increases, the need for secure, high speed communication systems increase as well. Quantum communications are a promising solution as they provide a much higher level of security than traditional communication methods. Quantum communication has gained prominence for its capacity to secure information through principles like entanglement and signal noise detection in the presence of eavesdropping. However, conventional quantum encryption faces vulnerabilities such as resend attacks, where intercepted signals are reconstructed and forwarded undetected. This technology offers a petahertz-scale squeezed light quantum communication method that offers increased security even over other quantum communication methods.
