Quantum computers use quantum algorithms in order to perform better than standard classical computers. Quantum algorithms are used for several purposes, including solving linear equations, search optimization, and cryptography.
Quantum algorithms that run on quantum computers are used to achieve an efficiency improvement over a classic computer algorithm. For a more detailed explanation, visit Quantum Computing News. Some popular uses of quantum algorithms include:
- Financial Modelling – The finance industry and companies within it constantly need to calculate each investment; companies need to analyze the risk associated with a certain investment, whether a return will be received on it or not, and other important factors that lead to a fruitful investment. Usually, all of this is done on classical computers; but since those take up too much time, companies in the finance industry have begun to switch over to quantum algorithms on quantum computers.
- Weather Forecasting – Classical computers tend to remain slow and take more time to get things done. When predicting the weather, once a classical computer has come up with a prediction, the weather must have already changed! This is because weather forecasts must take into account a lot of information before a prediction is made, including the temperature and air density. But the more information to sift through, the slower the process is on a classical computer. Hence, weather forecasting companies are shifting towards quantum algorithms to get faster predictions and more accurate information.
- Drug Development and Design – Developing drugs and medication is a core part of the healthcare system; a new drug being developed must undergo endless testing and trials before it gets approved. Quantum algorithms help to reduce the time it takes to curate the perfect drug; these algorithms are used to predict a drug’s effects on humans even before it is developed. This helps to reduce time spent on trials and make sure that life-saving medications enter the market quicker.
- Cyber security – We all know that the Internet is not the safest place to share a lot of our personal details, but we all still do it. Quantum algorithms are used to make sure that all the information you share online is secure and is not shared with any third parties. Such algorithms are used to identify and combat cyber security threats so that personal data stays safe.
- Computational Chemistry – Since quantum algorithms maintain the existence of 0 and 1 simultaneously, they are useful in pharmaceutical research. A good example of the future use of quantum algorithms is their ability to remove carbon dioxide from our surrounding environment.
