Quantum states are the fundamental entities in quantum mechanics that encapsulate all the information about a quantum system, typically represented by wave functions or state vectors in a Hilbert space. Their probabilistic nature underlies the inherent uncertainties and phenomena such as superposition and entanglement, distinguishing them from classical states.

Wave functions are mathematical descriptions in quantum mechanics that encapsulate the probabilities of finding a particle in various positions and states. They are fundamental to understanding the behavior of quantum systems, as they provide the basis for calculating observable properties through operators and the Schrödinger equation.

Hilbert Space is a complete inner product space that generalizes the notion of Euclidean space, providing the framework for quantum mechanics and many areas of functional analysis. Its structure allows for the rigorous treatment of infinite-dimensional spaces, making it essential for understanding wave functions and operators in quantum theory.

Superposition is a fundamental principle of quantum mechanics where a quantum system can exist in multiple states simultaneously until it is measured. This principle leads to the probabilistic nature of quantum mechanics, where the act of measurement collapses the system into one of the possible states.

superposition

Entanglement is a quantum phenomenon where particles become interconnected such that the state of one instantly influences the state of another, regardless of distance. This non-local interaction challenges classical intuitions about separability and locality, playing a crucial role in quantum computing and quantum cryptography.
