Quantum Key Distribution Using FPGA: A Real Time Prototype, Design, and Analysis - Paperbackby Noor Kareem Jumaa (Author), Firas Ali Sabir (Author) This book presents a study and analysis to investigate of a secret key sharing in quantum technique and try to increase the key length and security level in the sifting key stage. Enhancements in sifting key stage and error correction stage are done by repeating the QKD protocol and encoding the key bits before sending them by adding a C_QUBITS technique. After that, 60% base probability is used
