Abstract We investigate nonclassical properties of the quantum state generated by operating a two-mode Hadamard operator on the vacuum state. It is found that the scale length parameter of this new state plays an important role in squeezing. The anti-bunching effect, entanglement, and nonlocality are also derived analytically.
