Wave Function
A complex-valued function in quantum mechanics that describes the state of a quantum system, whose squared modulus gives the probability of finding a particle at a given location in space. It is the core mathematical representation in quantum simulation and quantum computing.

The Copenhagen interpretation holds that the wave function does not describe objective reality but is merely a probabilistic prediction of measurement results; collapse is not a real physical process but an update of knowledge state.
Quantum mechanics has a complete mathematical formalism and precise predictive power, yet the debate over "what the wave function actually means" has continued for nearly a century.
The wave function is the mathematical object in quantum mechanics that describes a system's state, usually denoted Ψ, containing the probability amplitudes of all possible measurement outcomes of the system.
For a system of n qubits, the dimension of the full wave function is 2ⁿ, which is the fundamental reason why the computational cost of quantum simulation grows exponentially with scale.
The wave function of N particles lives in a 3N-dimensional Hilbert space; this abstract mathematical space can have infinite dimensions, but it is a purely mathematical tool and not a physical space.
Quantum mechanics describes particles with a mathematical object called the wave function, which evolves like a wave until a measurement occurs; this wavelike evolution predicts the interference pattern observed in the double-slit experiment.
The many-worlds interpretation holds that the wave function never collapses and that every possible outcome continues to exist, distributed across different branches of reality — these branches are not the extra spatial dimensions of string theory.
