Unitary operators are fundamental objects in the field of quantum mechanics and linear algebra. They are linear operators that preserve the inner product in a complex vector space. Here’s a more detailed explanation: \#\#\# Definition: A linear operator \\( U \\) is called unitary if it satisfies the following conditions: 1. **Preservation of Norms**: For any vector \\( \\psi \\) in the space, \\( \\| U\\psi \\| = \\|\\psi\\| \\).
