Quantum physics is a branch of physics that deals with the nature of particles at the atomic and subatomic scale.

This branch of physics is the foundation of quantum chemistry, quantum field theory, quantum technology, and quantum information science. Its theories explain the nature of energy and matter in the simplest terms.

Quantum physics is based on two concepts: quantum mechanical systems and the Planck equation. In simple terms, the Planck equation is the relation between the frequency and the energy of a particle.

One of the concepts in quantum physics is the uncertainty principle, which describes how quantum objects have multiple positions simultaneously.

It is possible for an electron to exist in many places at once, and to take on different states. This property is known as superposition.

However, quantum field theories do not explain how electrons move in solids, which determines the type of material they are.

The concept of quantum theory was first put forth by Max Planck in 1900.

He was studying the color of radiation at the time and came up with an idea that made energy quantifiable.

This assumption became the first basic assumption in the theory of quantum mechanics.
