Too bad that you would be reading very old news Axil! By this time that alien and likely his species has become extinct.
You need a better link.

As the uncertainty in position rises with the widening of theaperture, the uncertainty in its momentum falls – allowing its direction to bedetermined with greater precision. In other words, telescopes with largerapertures have a smaller "diffraction limit". I say eliminate Heisenberg's uncertainty principle byusing weak quantum measurement. Base a photon detector on a double slit whereweak quantum measurements are performed. An optical backplane with many such nanoscale photondetectors can replace the big mirrors of the telescope. And computer orhardware logic can perform photon averaging and image reconstruction of that averagedphoton momentum data to build the image of a celestial object. This is the digitalequivalent of the analogy curve of the mirror. I want to read the newspaper of an alien over his shoulderfrom two billion light years away, so let’s get quantum digital.
