Quantum physics is a branch of physics that studies the behavior of matter and energy at a very small scale, such as atoms and subatomic particles. It explains how particles interact with each other and the forces that govern their behavior.
Quantum physics has revolutionized our understanding of the universe and has led to many technological advancements, such as transistors, lasers, and MRI machines. It also plays a crucial role in fields like chemistry, biology, and engineering.
Classical physics describes the behavior of objects at a macroscopic level, while quantum physics deals with the behavior of particles at a microscopic level. Quantum physics also introduces the concept of uncertainty, where the exact position and momentum of a particle cannot be known simultaneously.
In quantum physics, the behavior of particles is described by wave functions, which represent the probability of finding a particle in a particular state. This means that the behavior of particles is not deterministic, and can only be described in terms of probabilities.
Quantum entanglement is a phenomenon where two or more particles become connected in a way that the state of one particle affects the state of the other, even if they are separated by large distances. This concept is still not fully understood, but it has been proven through various experiments and has potential applications in quantum communication and computing.
