  • I read it. Doesn’t mention FTL, because that’s not a possibility for actually transmitting info.

    Edit: I think the way these quantum encryption systems work is that basically the photons (and I assume it’s polarization being measured) become the encryption key to a message that is sent conventionally.

    Like the sender generates a bunch of entangled photons, sends the paired ones to the recipient, measures their photons and uses the results to encrypt the message, the receiver measures theirs and gets the same results, the sender sends the encrypted message over email or whatever, and the recipient has the same key because of entanglement.
    Meanwhile an eavesdropper measuring the photons would mess them up for the recipient so the message wouldn’t decrypt.















  • Roller skating. I’m super unathletic, but skating (including teaching to others) was listed in the profile of a girl who contacted me on a dating site, so after chatting for a bit I suggested that as our first date. She was super patient with me, I had never put on skates before that day, and was in my 30s.

    We’re married now, and I now also teach skating where she does on weekends, sometimes to people who have never tried it before.
