We also give the exact value of the real polynomial Bohnenblust-Hille constant for $2$-homogeneous polynomials in ${\mathbb R}^2$. Finally, we provide lower estimates for the real polynomial Bohnenblust-Hille constant for polynomials in ${\mathbb R}^2$ of higher degrees. %K Bohnenblust–Hille constants %K Absolutely summing operators %K Quantum Information Theory %~ Universidad de Cádiz
