Quantum

Quantum refers to the branch of physics that describes the behavior of matter and energy at very small scales, such as atoms and subatomic particles. Unlike everyday objects, which follow predictable laws, quantum particles exhibit unique phenomena like being in multiple states simultaneously (superposition) and influencing each other instantly over distance (entanglement). These behaviors challenge classical intuition but are essential for understanding the fundamental nature of the universe and have led to technological advances like quantum computing and cryptography. Essentially, quantum physics reveals that nature at tiny scales operates differently than our everyday experience suggests, governed by probabilistic and wave-like principles.
