The Impact of Quantum Computing on Cybersecurity

In the computer based solutions of the problems in today’s world; if the problem has a high complexity value, different requirements can be addressed such as necessity of simultaneous operation of many computers, the long processing times for the operatsion of algorithms, and computers with hardware features that can provide high performance. For this reason, it is inevitable to use a computer based on quantum physics in the near future in order to make today’s crypto-systems unsafe, search the servers and other information storage centres on internet very quickly, solve optimisation problems in the NP-hard category with a very wide solution space and analyse information on large-scale data processing and to process high- resolution image for artificial intelligence applications. In this study, an examination of quantum approaches and quantum computers, which will be widely used in the near future, was carried out and the areas in which such innovation can be used was evaluated. Malicious or non-malicious use of quantum computers with this capacity, the advantages and disadvantages of the high performance which it provides were examined under the head of security, the effect of this recent technology on the existing security systems was investigated
