Practical Uses of Quantum Mechanics

Quantum mechanics is no longer an abstract, theoretical concept; it’s the backbone on which much of today’s technology operates. Fast computers, hybrid cars, and solar panels all rely on quantum mechanics to function optimally and provide us with some amazing benefits in the process. As quantum mechanics has become increasingly intertwined with technology, scientists are only now getting a better understanding of its potential and how it can be implemented in the technology we use every day.

Here is an in-depth look at five practical uses of quantum mechanics:

Quantum Computing

The fundamental driver behind how new inventions, like those mentioned below, can harness the power of understanding quantum mechanics is the creation of quantum computing devices. Governments and large companies are currently using quantum computing software for various purposes; for example, IBM researchers are using quantum computing to design new computer chips.

The idea behind quantum computing is to use algorithms that can account for quantum mechanics, enabling humans to solve problems faster and more accurately. Solving complex problems can be extremely time-consuming, if not impossible, with traditional computers. This makes the use of quantum computing a significant advantage for the progress of humankind moving forward. There is constant work being done on new quantum computing devices, and there is still a lot to be explored. As quantum computing becomes more advanced and accessible, the possible implementations are endless.


Quantum mechanics has been used to create a variety of modern technologies, but lasers are one of the most important and exciting. The first laser was created in 1960 by Theodore Maiman; since then, they have become an integral part of our lives. In addition to being used for a wide variety of technology in the medical field, lasers are also essential components for new kinds of defense technology, like guidance systems for missiles. Also, some countries are using lasers for communication. As the information age advances and we’re forced to send more information at shorter distances, lasers will become even more critical.


In addition to lasers, quantum mechanics have been used to create various nanotechnology-based technologies. Nanotechnology is a relatively new field in which scientists aim to build extremely small machines that could revolutionize our technology and everyday lives. And while we aren’t quite there yet, the discovery of quantum mechanics led to the creation of nanoscale machines. Quantum computers and transistors are two areas of nanotechnology that have directly benefited from quantum mechanics. In addition, quantum mechanics have been used to create new artificial materials that could revolutionize how we interact with our world.

Electron Microscopes

This is a field of technology that relies almost entirely on the use of quantum mechanics. Electron microscopes are considered by many to be some of the most important tools in modern science; they have been used in everything from helping to create new kinds of materials and manufacturing technologies to being part of NASA’s Rover program exploring Mars. Like scanning tunneling microscopy, electron microscopes allow us to look at things on a molecular scale. Electrons can be manipulated more easily than light particles (photons). In addition to being used in the medical field and nanotechnology, electron microscopes are also essential in chemistry and physics.

MRI Scanners for Medical Imaging

MRI scanners are a crucial part of modern medicine, used for everything from diagnosing brain damage and cancer to aiding in organ transplants. However, these scanners rely on the laws of quantum mechanics to create images that can be used for medical purposes. MRI scanners are based on the discovery of nuclear magnetic resonance, which is the basis for a huge amount of technology in the medical field. In MRI scanning, magnetic fields are used to manipulate the protons within an object and create images that can help doctors understand what is happening inside a patient. These scanners have been crucial for modern medicine, but much more research is needed to improve their effectiveness and reliability.


Quantum mechanics is fundamental to our lives and the world around us. Recent discoveries made within quantum mechanics have led to various inventions that people use every day. Quantum physics has solved many problems in the past, but there’s still much to be explored and improved upon. With this in mind, the push to leverage our current understanding of quantum mechanics will continue to play a vital role in keeping humanity safe, healthy, and prosperous. Therefore, there is no doubt that quantum mechanics will remain an essential part of human discovery in the future.
