New calculations suggest that the event horizons will eventually “decohere” quantum possibilities—even those that are far away.
Importantly, your detector doesn’t have to be close to the slits to figure out which path the particle took. A charged particle, for example, emits a long-range electric field that might have slightly different strengths depending on whether it went through the right-hand or left-hand slit. Measuring this field from far away will still allow you to gather information about which path the particle took and will thus cause decoherence.
Then along comes Bob, who is attempting to measure the particle’s position from far away by measuring the particle’s long-range fields. According to the rules of causality, Bob shouldn’t be able to influence the outcome of Alice’s experiment, since the experiment should be over by the time the signals from Bob get to Alice. However, by the rules of quantum mechanics, if Bob does successfully measure the particle, it will become entangled with him, and Alice won’t see an interference pattern.
He posed a thought experiment to his collaborators: “Why can’t I put [Bob’s] detector behind a black hole?” In such a setup, a particle in a superposition outside the event horizon will emanate fields that cross over the horizon and get detected by Bob on the other side, within the black hole. The detector gains information about the particle, but as the event horizon is a “one-way ticket,” no information can cross back over, Danielson said.
