Quantum Mechanics: The Building Blocks

Quantum Mechanics

Quantum Mechanics is the branch of physics that studies the behavior of matter and energy at the atomic and subatomic level. It provides the framework for understanding the fundamental properties of the universe. The theory of quantum mechanics is based on a set of principles that are quite different from those of classical mechanics. One of the key differences is that in quantum mechanics, particles can exist in multiple states at once, a phenomenon known as superposition.

Wave-Particle Duality

Another important concept in quantum mechanics is wave-particle duality. This refers to the idea that particles can exhibit both wave-like and particle-like behavior, depending on the experiment being performed. This duality is encapsulated by the Schrodinger Equation, which describes how the wave function of a system evolves over time.

Heisenberg's Uncertainty Principle

Heisenberg's Uncertainty Principle is a central concept in quantum mechanics. It states that the more precisely the position of a particle is known, the less precisely its momentum can be known, and vice versa. This principle places fundamental limits on the accuracy of measurements.

Entanglement

Quantum mechanics also introduces the notion of entanglement, where particles can become correlated in such a way that the state of one particle is determined by the state of the other, no matter how far apart they are. This phenomenon has been demonstrated experimentally and is a key component of quantum computing.
