Quantum Computing Based Technique for Cancer Disease Detection System IntroductionThe current era is the modern era dedicated to science and technology, as science improves itself with the Over time, the human race loses its tolerance for various diseases and lifestyle and environmental changes make the condition worse than ever. As the story depicts, we never lose hope and the same thing happens in the current scenario. Cancer is one of the most devastating diseases faced by humankind and with time we are getting various diagnosis and detection technologies in this regard which create a platform for better treatment. In the same path we use classical computing as a faster tool than manual analysis and other tools, but since it also requires more time than more advanced quantum computing, there is a lot of scope here with researchers to do some work in this regard. In the following pages I will try to elaborate such things which could be a boon in the field of medicine in the near future. The detection technique used in the following work is a collaboration between Quantum Computing and Clustering Techniques. Quantum computing is a multidisciplinary research area that brings together ideas from: Information Theory, Computer Science, Mathematics and Quantum Physics.1.1 Quantum MechanicsQuantum mechanics is a set of mathematical rules or structures for building physical theories. For example, quantum electrodynamics which describes the interaction between atoms and light with extraordinary precision. 1.2 Quantum computing Quantum computing is essentially about harnessing and exploiting the amazing laws of quantum mechanics to process information. The key to improving computer performance was reducing the size of transient states......in the center of the paper......and at the same time. • Quantum computing can perform computations on all superposition states at once. • It will be able to perform any task of a classical computer. • It could process huge amounts of complex data. • Ability to solve scientific and commercial problems. • Process data at a much higher speed. • Ability to provide more accurate answers. 1.7 ChallengesThe following changes have been detected for the initiation of disease detection system.• Correlate quantum computing with cancer disease detection.• Diagnose accurate data timely.• Process data at a much faster speed.• Cancer it is not just a disease but actually such a syndrome, data collected from a single factor could be deemed incorrect. In this regard, the collection of data from different factors and their simultaneous interpretation is necessary to obtain a more accurate result.
