If I understand correctly, the paper asks us to imagine Alice's friend making a 'classical' coin flip, and Alice modeling and measuring her friend's lab as if the coin flip were a quantum superposition of coin heads/coin tails.
But this is simply wrong. The error creeps in in the second assumption:
> An agent can analyze another system, even a complex one including other agents, using quantum mechanics
This is likely a good assumption, but quantum physics would tell Alice that the coin's atoms are all firmly in a state corresponding to either 'heads' or 'tails'. The author is actually making the following assumption:
> What we classically think of as chance is completely interchangeable with the unpredictability of quantum superpositions.
This notion has already been proven wrong many times over.
I think there is confusion between some of the terms he is using. I don't believe this is a secret call so much as one where the parties are unidentified. The contents of the phone can be trapped, and if there is any exchange of identifying information, an investigation can be successful.
With burners at the 7-11 they seem to want buyer information, even with cash. I have yet to find an untraceable burner.
Back when I worked at Google, a friend of mine got an unpleasant email from r@ because his Python script had a bug: it sent alerts to the individual characters of [email protected]
I've heard his email causes issues for tons of internal systems at Google because a lot are coded with the expectation of a minimum of 3 characters for the left part of the email. May just be urban legend though.
Yes and no. Yes, they belong to the same employee; no, each google.com mailbox needs to be approved, they are not automatically redirected unlike regular GMail addresses.
This leg uses advanced AI and Machine Learning algorithms with a cloud Prosthetic as a Service (PaaS) model. Utilizing the latest in state of the art open source blockchain technology, this leg will bring added value while synergizing with your efficiency to optimize your bottom line.
The true cost of a digital currency in the energy required to mine new blocks of currency. By using just a fraction of the energy naturally generated through the movement of the leg while walking, each step could bring you more wealth in STRIDE coin(™).
