There are at least two sci fi stories based on the premise of vacuum-creating quantum black holes. In one, ("The Hole Man" by Larry Niven) aliens left such a device on Mars. Astronauts discover it, and one of them manages to release it from the force field that holds it in place, with disastrous implications for Mars.

In the other story (whose title I don't recall, but it was probably published in Analog), a bare something (perhaps a wormhole whose other end is in open space) is created, and begins to suck the Earth's air away. The hero builds a dome around it, but leaves a valve in the side to sell vacuum.
