Security in the context of future communication challenges and compressive sensing


Joint project with Prof. Jens Eisert, Quantum Information Theory group, Freie Universität Berlin.



The proposal suggests a concerted effort to tackle and resolve key challenges in the development of communication technologies—examining physical layers of security in future mobile phone and quantum technologies that offer the perspective of unconditionally secure communication. It exploits and further develops methods of compressed sensing as the main “hammer” to be used. The proposal brings together significant expertise from electrical engineering and mobile phone communication, quantum information science, and applied mathematics, with both principal investigators having a significant track record in research on modern signal processing and specifically compressed sensing. Formally, it will introduce novel ideas of deconvolution further developed from the emergent sub-fields of blind deconvolution and bi-linear form estimation under new conditions of incoherence and notions of compressibility, as well as non-commutative analogs that naturally arise in the quantum setting, and apply them to the practical problems of information processing at hand.
