Keywords: analysis of quantum algorithms, quantum computation, quantum programming, quantum walks on random graphs.
While the excitement in the area of quantum computing is fully justified by the new theoret-ical developments, year by year scientists have discovered new limitations of quantum com-puting devices. In particular, unitary operation decomposition provides a number of problems including the applications to hardware with fixed topology. Moreover, quantum algorithms have been proved to be sensitive to noise, which may impact the results of the computation. This resulted in the development of a new branch of quantum computing, namely the theory of quantum error-correcting codes. This aspect became even more critical when first commer-cial quantum computing systems became available. Furthermore, for quantum cryptographic protocols, hardware attacks, based on the security holes of conventional electronics, have been discovered. This demonstrated that the theoretical security confirmed by the laws of physics in the ideal environment could lead to the creation of insecure protocols the real-world applic-ations.
The main focus of the proposed thesis is to develop theoretical methods suitable for analysing the impact of quantum program alternation – input data modification or imprecise implement-ation of the algorithm – on the efficiency of quantum algorithms. Quantum program is a se-quence of quantum operations and the quantum representation of input data which are sent to the quantum processor. In some ceases we can consider quantum program alternation as a ac-tion of a malicious party and in this scenario we can understand it as an attack on quantum processor or quantum program.
Proposed project will be conducted in the scope of Polish National Science Centre project
