Quantum states of a system

Quantum states describe the condition of a tiny particle or system at the quantum level, such as electrons or atoms. Unlike classical objects with definite positions or speeds, quantum states encompass all possible outcomes simultaneously, encoded in a mathematical object called a wavefunction. When measured, the quantum state "collapses" to a specific outcome. These states contain probabilities, meaning they tell us the likelihood of finding a system in a particular condition but do not determine it with certainty until observed. Overall, quantum states provide a comprehensive way to understand and predict behaviors of microscopic particles within the probabilistic nature of quantum mechanics.
