Quantum physics is the branch of science that explores the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. Unlike classical physics, quantum physics reveals a “weird” and counterintuitive world where particles can exist in multiple states at once (superposition), influence each other instantly across vast distances (entanglement), and behave both like particles and waves.

Key principles include:

Wave-Particle Duality: Light and matter exhibit both particle-like and wave-like properties.

Superposition: Particles can exist in multiple states simultaneously until observed.

Quantum Entanglement: Two or more particles can become linked, affecting each other regardless of distance.

Uncertainty Principle: Certain properties, like position and momentum, cannot be precisely measured at the same time.

Quantum physics underpins technologies like lasers, transistors, and quantum computers. It challenges our understanding of reality, making it one of the most fascinating and revolutionary fields in science.
