      What are Eigenvalues and Eigenvectors?

      Introduction to Quantum Computing

      Eigenvalues and Eigenvectors

      Eigenvalues / Eigenvectors

      • eigenvalue is the factor that the "span" is stretched along the eigenvector
      • the axis of rotation in 3D space
        • the eigenvector that stays on its "span"
        • think about the angle of rotation
      • is easier to think of than staying with the coordinate system
        • A is the transformation matrix
        • λ (lambda) is a scaler
        • Eigenbasis
