Group Quantum Technologies Laboratory



Research carried in QT Lab focuses on developing novel concepts for optical communication systems, employing recent advances in quantum information science and quantum optics. Rather than transmitting information in classical variables, such as the intensity of the phase, QT Lab aims to reformulate the communication task as the identification problem for non-orthogonal quantum states describing individual inputs. This approach, supplemented by state-of-the-art optical signal processing and quantum-level characterization, opens new avenues toward sub-shot-noise error rates and superadditivity of accessible information.
