I'm a lawyer, so my explanation can be a bit flawed.

Some variation of Einstein-Podolsky-Rosen conception? You can measure
any photon as wave. The problem is, if an entangled photon has been
measured before, it will change - statistically - the results of the
measuring of the second photon. But the problem is that you will know
what the results should be when you get the results of the first
measurement.

So you can transmit information quicker than light - but you cannot
decode it.
