Is this what they did to bring us the high resolution picture of a black hole? If not could that method be used by these hypothetical hubbles?

- martythemaniak 6y agoIt sounds like the parent is referring to a specific type of interferometer, because yes, this is what they used on the EHT and it did not have any such entanglement or quantum effects.
- ncmncm 6y agoActually regular light-wave interference suffices, but it's quantum anyway, just because that's how light is.

That was using radio waves, something that can be measured in each telescope, saved as data, and then combined in a computer. At optical wavelengths we cannot record the data as accurately/quickly and so must instead use extraordinarily precise mirrors and fiber optics to join the light from each telescope in real time. These links must be accurate in distance to within a wavelength.
