What is Meant by Applied Quantum Computing?

The world of quantum computing is one that has excited technologists and scientists alike for some time. But what is meant by applied quantum computing? In essence, the term ‘applied quantum computing’ refers to the practical application and implementation of quantum computing algorithms and techniques to solve real-world problems. Such applications of quantum computing can be used to solve problems in fields such as medicine, finance, engineering, and many other areas where complex and extensive calculations are necessary.

A Brief Introduction to Applied Quantum Computing

Before getting into the details of what is meant by applied quantum computing, it is crucial to understand the basics of quantum computing. Quantum computing relies on the principles of quantum mechanics, the subfield of physics that deals with the behavior of matter and energy at a tiny scale. It includes understanding the nature of energy and matter on the atomic and subatomic levels.

Quantum computers use quantum bits (qubits) as opposed to traditional bits. These qubits can exist in a superposition of states and have the ability to be in multiple states at the same time, unlike classical bits that can only exist in one form at a time. This quantum computing capability allows it to tackle mathematical, physical, and computing problems that are intractable with traditional computing, store and process large amounts of data faster and more efficiently, and provide accurate results to much higher levels.

Applied quantum computing seeks to utilize these capabilities in order to provide solutions to real-world problems, which involves the application of quantum computing algorithms to a specific issue or set of problems. For example, they can calculate and simulate how drugs interact with proteins at the molecular level. This could provide information that will lead to more effective treatments for various diseases.

In addition to drug design, applied quantum computing can create more efficient and accurate financial models, develop algorithms for pattern recognition, and build models for forecasting markets and economic trends. With the ability to crunch large amounts of data in a fraction of the time traditional computers would take, applied quantum computing can provide an enormous amount of data and insights to businesses.
