Quantum physics, also known as quantum mechanics, is one of the most fascinating and complex fields of science. Although it may seem intimidating at first, understanding the basics can open a new world of knowledge and curiosity. In this blog, we will discuss the fundamentals of quantum physics, making them accessible to beginners.

• What is Quantum Physics

Quantum physics is a branch of physics that studies the behaviour of matter and energy at the atomic and subatomic levels. It is totally different from classical physics, which describes the macroscopic world we can see and touch. In short, quantum physics highlights the counterintuitive behaviours of particles like electrons, photons, and atoms.

• Wave-Particle Duality

Wave-particle duality is a famous concept in quantum physics. According to this principle, particles can exhibit both wave-like and particle-like properties. Light, for example, can behave as both light and a wave depending on how it is observed. Many quantum phenomena are based on this duality principle.

• Superposition

Another key concept in quantum physics is superposition. It highlights that a quantum system, such as an electron, can exist in multiple states simultaneously until and unless it is measured or observed. For instance, an electron can spin both clockwise and counterclockwise at the same time.

• Quantum Entanglement:

This phenomenon is known as quantum entanglement, which occurs when two or more particles become interconnected. It states that one particle instantly influences the state of other particles, regardless of how far away they are. Entanglement has potential applications in quantum computing and quantum cryptography.

• The Quantum State and Wave Function

A particle’s properties are mathematically described as a quantum state. It may include the particle’s position, momentum, and spin. On the other hand, the wave function is a mathematical tool used to describe the quantum state of a system. The key feature of the wave function is that it offers probabilities of where a particle might be found.

• Applications of Quantum Physics

Quantum physics has numerous practical applications in the real world. Technologies such as transistors, lasers, MRI machines, and even GPS rely on quantum mechanics principles.

• Conclusion

Finally, while quantum physics may seem complex, the basic principles discussed in this blog are key to grasping this fascinating area of science.
