I've been thinking...

...about the next Mission Impossible movie.

Seeing they spend so much time on accessing encrypted information stored in places using the weirdest security systems, can't the writer look into something more realistically at the cutting edge, such as quantum cryptography?

Now, I guess the point of that is to make information genuinely impossible to break into, but there is nothing impossible to Ethan Hunt, as we were told in the last movie.  (Perhaps he can be split into a both dead and alive version in a Schrodinger's Cat upscaling.   Would that help with quantum cryptography?   Who cares?)
