An Invisible Quantum Tripwire

I came across this paper on arXiv today: An Invisible Quantum Tripwire. It is a short read (4) pages, and pretty interesting. It basically expands the bomb experiment, where the presence of a bomb can be detected without measurement- albeit with only a 25% chance of successful detection. (That cannot be done classically.) The paper also introduces that experiment.
