Quantum Communication. All systems described by quantum mechanics can display so-called entanglement, for example, the spin of one electron cannot be known in advance of a measurement yet will be perfectly correlated with the other, even if it is in a distant location. This has recently been verified (Oct 26, 2015).

At an agreed upon time, the observer on Earth influences the particles and the party on Mars observes the states and both then know the initial states of each box. At a certain time later, the party on Earth influences the particles so as to change the states of some according to a pre-agreed “code”. Could not the party on Mars then “instantly” determine the states and the message from Earth based on the code?
