Quantum computers would be  rare and exotic research resources anyplace
in the world.....

I might point you to history and the Enigma machine.

  http://en.wikipedia.org/wiki/Enigma_machine

You can research (compare and contrast) computers used
at Bletchley Park with machines today and also explore the
mathematics and  probability changes as the number of rotors
and rotor taps  change.   Changes in the taps and rotor counts
are easy in  software.

Enigma while broken in war time is still an interesting and
quality encryption method.   Especially if the virtual wheel
wiring, wheel count and other physical limits are coded to
be extended in software.

It is possible to code an Enigma machine in any modern
programming language in a portable way (Python for example).

If you feel inventive explore the Rubic's Cube as an encryption device.
As a combinatorial tangle it has challenges especially if grown
beyond the basic 3x3 face of a cube and six colors.
The puzzle has solutions because the stickers are a known text.
But what if the stickers were an unknown text....alphabet?
