Bio:
Paolo Villoresi is a Full Professor of Physics and Director of the Padua Quantum Technologies Research Center, both at the University of Padova. He studied Physics and Applied Mathematics at University of Padova, where he is permanent faculty since 1994. He proposed in 2002 and then realized the first single photon exchange with a satellite using the ASI-MLRO telescope in Matera. He founded a research group on Quantum Communication (QC) and Quantum Optics, that demonstrated the first QC in Space using orbiting retroreflectors, adopting polarization and temporal modes. His group also have shown the first use of OAM modes in QC, the study and mitigation of turbulence in free-space QC in the 143km link at the Canary Islands, as well the implementation of novel QKD protocols and of fundamental tests of Quantum Mechanics both in Space and in the Lab. The daylight free-space quantum QKD using integrated photonics circuits as well as QKD inter-modal networking are among QuantumFuture recent results. Another research line is in the generation of random numbers using discrete and continuous quantum variables, introducing new protocols and realizing them in quantum processes reaching generation rate of tens of Gbps. He has deposited 14 industrial patents and patent applications. He is also founder and President of ThinkQuantum, a spinoff of University of Padova introducing advanced QKD technologies for Space and ground networks.
Abstract:
We present the study of the communication system designed to transmit data from an ultralight sail on an interplanetary mission. Starting with the estimation of parameters such as divergence and power required, we arrive at the dimensioning of the transmission system. This is achieved with phased-array grating couplers. Some implementation models for these devices are presented. Finally, the optimal error-correction code for this type of communication has been worked out and will be briefly presented. By drawing inspiration from the methods of Quantum Communication in space, the preparation of the pulses required for communication from the sail can also provide significant metrological information for studying the kinematics of solar sails.
