Interesting, a sort of quantum eruv https://en.wikipedia.org/wiki/Eruv

Does anyone have any additional context on the throughput numbers? It says 20k photons per second at 99% fidelity and 500k at 90%, but what is the actual bandwidth needed for reasonable usage / computation?

This is great but why can’t i get fiber internet in my bk apartment. Still struggling with spectrum coaxial pulling less than 5mbps today. No options on my block. Sheesh

Find a new apartment? Here's the FCC broadband map: https://broadbandmap.fcc.gov/home

> In addition, it is also forbidden to transfer an object for a distance of 4 cubits

This gave me pause.

In a public area you can not transport objects, the intention being that the Sabbath is a day of rest, and you should stay home or at least near your home and not do work.

Note: Jewish law very carefully defines "public area", and it would take several pages of text to fully explain it, so before objecting be aware you may be lacking background knowledge.

20k (10^4) photons/sec is a TINY amount.

An ordinary flashlight emits something like 10^18 photons per second. Even a star in the night sky sends around 10^8 to your eye.

That few photons is not going to have much bandwidth.

Is this solution to every issue in the US? Like if something is shit then instead of fixing just run from the problem? I guess that’s why you are stuck choosing between republicans and democrats every 4 years lol.

Doesn't that map consider an entire region serviced if a single residence in that entire region can get the advertised speeds?
