BB84 Demo

This demo was originally written as a Perl CGI script for a course taught by Neal Young at Dartmouth College, which is where I studied computer science as a grad student.

I am now a software developer at athenahealth. I have rewritten the demo using PHP. Please email me with any suggestions for improvements. This demo was previously located at Dartmouth and Mercersburg.

Go on to the demo now.
