I live in a large midwestern city. They aren't common by any means but they definitely exist. I'm sure more expensive properties are more likely to have features like this but I've seen starter homes in the mid $100k with scans.
They really helped me as a buyer and while I don't know what they cost, I think I'd spring a couple hundred dollars to have it whenever we sell our house.
I think the biggest problem is that as a seller, I want qualified leads, but I get the feeling realtors just want leads because there's always another house. This mis-alignment of incentives means that in my experience listing agents don't always want to take steps that would limit foto traffic to a property, even if it would be excluding parties that probably wouldn't buy.

Doesn't current quantum teleportation require optical connectivity because the state transfers along photons?
The abstract says
>Here, we report the demonstration of chip-to-chip quantum teleportation and genuine multipartite entanglement, the core functionalities in quantum technologies, on silicon-photonic circuitry
So while there may not necessarily be a phsyical connection this does require line-of-sight by my read, and "silicon-photonic circuitry" sounds like this is all on one physical board.
I guess I don't understand how this is "two different chips" as the article claims. Did they use two photomasks? Baby steps, I suppose.
This is an interesting thought. Over the holidays I've been watching my TV than I would during a normal week and I've noticed that my time in front of the screen is much different when there are commercials (forced 2 minute breaks) than when there are not commercials.
I own a couple of these. Because it has multiple options for virtual assistants, nothing is running out of the box as it wouldn't know which account to use or what service to route to. You have to go through an additional setup process after setting up the speaker for music playback.
