= State (functional analysis)
{wiki=State_(functional_analysis)}
In the context of functional analysis, particularly in the theory of quantum mechanics and quantum information, a "state" refers to a mathematical object that captures the information about a physical system. Here's a more detailed explanation: 1. **Quantum States**: In quantum mechanics, a state represents the complete information about a quantum system. It can be described in various ways: - **Pure States**: These are represented by vectors in a Hilbert space.
