Quantum Communication is the next frontier of Optical Communication where Quantum Optics effects are exploited to revolutionize tomorrow’s communication networks providing simultaneously unconditional data security. Integrated Photonics is expected to play an important role in making Quantum Communication systems get out of the laboratory, favoring their ingress and widespread use in real life applications. PNTLab is involved in study, design, fabrication and testing of basic functional blocks and more complex subsystems on chip for quantum state manipulation to be used in terrestrial and space Quantum Communication Systems.
