8 Ways Quantum Physics Is Quite Useful In Everyday Life

One of the significant benefits of enrolling children in physics tuition is that they will be able to apply what they learn to everyday life. Whether it be classical, optics, acoustics, mechanical physics, or quantum physics, children will learn everything they need to with the help of a tutor dedicated to helping them understand the subject a little deeper.

Quantum physics, in particular, discusses in depth the theory of every object that is isolated from its surroundings. Essentially, it is a theory of an atom’s microscopic world and its sub-atomic particles. This theory is used in many different ways in everyday life.

How is quantum physics used in everyday life?

1. Fluorescent lights

The Quantum phenomenon is responsible for the light you get from those tube lights or curly bulbs. A small amount of mercury vapour, which can emit light into the visible range, is exited into the plasma and gives light to fluorescent bulbs.

2. Computers and mobile phones

The computer system we can’t live without is based on the quantum physics principle. It forms the basis of the band structure of solid objects on which semiconductor-based electronics are built. Through the study of the nature of electrons, computer engineers are able to manipulate silicon’s electrical properties.

3. Bread toasters

Bread toasters are believed to be the reason why quantum physics was discovered. When the rod in your toaster gets hot, it turns red and heats the bread. The red-hot glow that your toaster emits every time you heat food in it is what started quantum physics.

4. Transistors

This electronic component is responsible for switching the electrical signals and power of different electronics. It is used in circuits in a wide array of electronic devices, including computers, mobile phones, smartwatches, microprocessors, register circuits, and more.

5. Global Positioning System (GPS)

Quantum physics has allowed people to easily navigate unknown locations using mobile devices that pick up signals from multiple clocks. Also, the distances between destinations are calculated from different satellites, each of which is equipped with an atomic clock that relies on quantum physics.

6. Magnetic Resonance Imaging (MRI)

Also known as Nuclear Magnetic Resonance, MRI involves the reversal of the spins of electrons in hydrogen nuclei, which is the shift in energies, a quantum physics application.

7. Telecommunications

Quantum physics played an essential role in making communication easier. Thanks to it, fibre optic telecommunication has been made possible, allowing people to be connected anytime, anywhere.

8. Lasers

Quantum physics is also the basis of the principle on which lasers work, which involves thermal emission, spontaneous emission, and fluorescence. The external protons, which are at a frequency associated with atomic transition, also affect the quantum mechanical state of the atom.


A lot of the electronic devices used every day are designed based on quantum mechanics. This is why it’s important that young children are encouraged to study physics so they can better appreciate its many applications.
