laser targeted comedy. reminds me of an old friend who was genuinely a prolog fanatic.

you can get it by setting your search region to china.

a quick internet query turned this up: https://deervo.itch.io/diskclick. it includes a file for a "1984 quantum q540" and a "quantum bigfoot 2110at" and several others.

in my view the idea of "the true me" smells a lot like woodstock era burger individualism. one's identity is something which is socially determined and not essential. There isn't a formula for eudaimonia. both striving for virtue and for authenticity can become toxic. i suggest you trust the people you hold close.

no the point is that you can transfer /quantum/ states by only directly sending /classical/ information

close! Let me give some more detail.

There are 3 "objects" to consider here

  • the initial state I want to teleport, call it |ψ>
  • the bell pair, |β₀₀>, which consists of /two/ entangled photons "P1" and "P2".

First, I make a bell pair (P1,P2), and apply some quantum operation interacting P1 with |ψ>. Then I measure P1 and |ψ>, which will give me two bits of information "M1","M2". I send to my friend over the optical fibre: the photon P2 (quantum), and M1,M2 (classical). Then, they can apply some operations which are decided by M1,M2 onto P2 and they will get back the original state |ψ>.

there is an analogy to RSA (if you're familiar), where the shared bell state is kind of like the key pair, encryption corresponds to combining the original state and measuring, and decrypting corresponds to applying the operations to the other half of the bell pair.

The advantage here, over sending the initial state |ψ> directly over the optical fibre, is that the bell state can be established by e.g. a third node sending half of a bell pair to each party, so that we only need to communicate classically to achieve quantum teleportation.

But also, quantum teleportation is a means of moving quantum states between different /types/ of qubit - of which there are many, which are good for different things.
