Researchers at the University of Calgary and the Southern Alberta = Institute=20 of Technology are working together to develop technology that will keep=20 information safe for the long term =E2=80=94 50 years or more.
The research involves encrypting information for quantum computers, = expected=20 to be the next generation of computer development.
Experts say current encryption systems will become obsolete.
On Wednesday, the researchers sent data, which they say cannot be = hacked,=20 between the two institutions using quantum technology.
The two post-secondary institutions are trading the information via=20 traditional telecommunications.
But Wolfgang Tittel, a U of C science professor, said the signal can = be=20 locked and cannot be copied or eavesdropped without it being noticed. An = unbreakable quantum key is used in transmitting the information, Tittel=20 said.
"Now these keys we distribute have the particular that if they are = corrupted,=20 they will tell us about being corrupted. That's a very powerful thing = that you=20 do not generally get in the traditional key distribution world, in the=20 traditional telecommunications world."
So far, the researchers can send the protected information only = within a=20 100-kilometre distance but they're working on extending that.
They are also trying to find the right firewalls, so the information = can't be=20 hacked through a back door.
