Quantum Fourier Transformation and Clifford Gate-Driven Secure Communication Model for Smart Grid Environments

Smart grids (power distribution systems that communicate usage data electronically) currently use classical public-key cryptosystems (encryption methods based on mathematical problems that are hard to solve) to protect power consumption information, but quantum computing threatens to break these systems. This paper proposes QC-EAM, a new security model using quantum encryption and quantum Fourier transformation (a quantum algorithm for processing data) to protect smart grid communications, tested on IBM's quantum computing platform.
