A simple approach to estimation of the ground state energy of quantum antiferromagnets is developed, based on the approximation that quantum fluctuations around different bonds are independent. A transformation of the spin operators to generate bond quantum fluctuations is devised and applied to the classical ground state of the S=1/2 Heisenberg model on the square lattice. The ground state energy estimates are as good as spin wave theory or slightly better. This simple picture of quantum fluctuations might be useful in more complex models.
