foundational aspects of quantum mechanics

Quantum mechanics is a branch of physics that explores the behavior of very small particles, like electrons and photons. It reveals that these particles can exist in multiple states at once, a phenomenon known as superposition. When measured, they 'collapse' into one state, revealing inherent unpredictability. Additionally, particles can be entangled, meaning the state of one instantly affects another, regardless of distance. Quantum mechanics challenges our classic notions of certainty and locality, fundamentally altering our understanding of reality and leading to technologies like lasers and quantum computing.
