Yes, this came up on Facebook. They don't actually say they did it, just that they see a way of doing it.
The problem is that interference is caused by the Principle of Superposition; the E fields are algebraically additive. Without the Principle of Superposition, there could not be any resultant E field caused by the algebraic vector addition of several individual E fields. When one E field vector goes "up" and one goes "down", the resultant is only zero because of superposition and algebraic vector addition.
However, the Principle of Superposition is possible with photons only because photons are bosons. An infinite number of them can occupy the same state. Neutrons are fermions, by the Pauli Principle, there can be no superposition for fermions.
