Usually when someone in tech says the word “quantum,” I put my hands on my ears and sing until they go away. But while IBM’s “quantum computing safe tape drive” nearly drove me to song, when I thought about it, it actually made a lot of sense.
First of all, it’s a bit of a misleading lede. The tape is not resistant to quantum computing at all. The problem isn’t that qubits are going to escape their cryogenic prisons and go interfere with tape drives in the basement of some datacenter or HQ. The problem is what these quantum computers may be able to accomplish when they’re finally put to use.
Without going too deep down the quantum rabbit hole, it’s generally acknowledged that quantum computers and classical computers (like the one you’re using) are good at different things — to the point where in some cases, a problem that might take incalculable time on a traditional supercomputer could be done in a flash on quantum. Don’t ask me how — I said we’re not going down the hole!
One of the things quantum is potentially very good at is certain types of cryptography: It’s theorized that …read more
