This got me thinking of quantum computers in general, the next day I came across this story from the New York times about how scientist's reported finding a reliable way of transferring data by quantum teleportation across 3 metres here is the link.

This then got me thinking what if you had the quantum computer with the quantum teleportation and where able to send information not across a distance but to the past.
So instead of sending a person back in time like back to the future which will be extremely complex you just send 1's and 0's.
The best way to send those 1's and 0's would be an email.
So the earliest you could send it would be 1974 if your father worked for the military or worked at a University. Or when email became popular in 1990's. This means history can only be altered from this time on.
What would you send?
