And while we may view it as probabilistic, it will either interact with our equipment or it won&#x27;t. If it doesn&#x27;t, communication failed. But yes, I wondered about that when writing my comment. Certainly photons are more than just &quot;bullets&quot; that are getting more and more sparse. So I got curious and it seems[1] that in context on our detector you can indeed put hard bounds on where the photon may be received. As far as I understand it, based mostly on the abstract, I do not really grasp it. But ignoring the paper, I think I get…</p><p><a href="https://hackerpaper.kaipfister.de/p/0903.3712/">Paper and discussion history</a>. A mention is not an endorsement.</p>quant-ph
