| Main Objective: The main scientific objectives of this project are: 1. To propose secure bit commitment and oblivious transfer quantum protocols based on CV. To improve the security of the proposed protocols through their experimental validation in a real channel. 2. To evaluate the capacity of an optical fiber for low-energy optical signals through the investigation of the channel capacity in a scenario where each symbol used to transmit information contains only few-photons. We intend to increase the number of bits sent per photon; 3. To optimize the transmitter and the receiver for weak coherent fields. Moreover, we also intend to develop post processing techniques as a solution to improve the efficiency of phase and amplitude information recovery from low-power signals. |
