Quantum Signal Processing in Strengthening Cyber Defense: A Comparative Study

Abstract

Aim: To examine the strengthening of cyber defense using Quantum Signal Processing.      Significance of Study: There is need for the application of Quantum Signal Processing in cyber security due to the vulnerable attack. This paper addresses the relevant issues on the use of Quantum Signal Processing in strengthening cyber defense. Problem Statement: The development of cyber space and its inestimable contribution in information dissemination has led to its wide patronage and usage. Thus, third party are intruding to hijack and hack secretive information to suite their own purpose.    Discussion: The concepts of Quantum Signal Processing (QSP) and cyber defense were examined. It was revealed that the measurement of Quantum Signal Processing is strongly involved in signal processing of algorithms design with significance to QSP framework such that in this framework, the processing of signals occur via the utilization of some Quantum Signal Processing measurement variables or subjecting them to a Quantum Signal Processing measurement. Also, the QSP framework is primarily assigned with the quantum physics constraints, QSP measurement design, a quantum measurement, borrowing from the principles, and axioms. Nonetheless, the measurement consistency principle, measurement concept and quantization of the measurement output principle were identified as the three interconnected fundamental principles of quantum mechanics in Quantum Signal Processing. The existing correlation between QSP framework and quantum physics together with relevant key results were also examined. was also discussed with major Considerations were given to modification of known algorithms, measurement parameters utilization, probabilistic mappings, imposition of inner product constraints and oblique projections as the algorithm design in quantum signal processing framework. Conclusion: In conclusion, Quantum Signal Processing is applicable in strengthening cyber defense.
