Schrödinger's cat lives and dies in two boxes at once
Physics World ^ | May 27, 2016 | Staff

Posted on 05/27/2016 11:17:02 AM PDT by C19fan

Schrödinger's cat now has a second box to play in, thanks to an international team of physicists that has created a two-mode "Schrödinger's cat state" for the first time. The experiment brings together two purely quantum properties, in that the "cat" (i.e. the photons) is simultaneously "alive and dead" (in a superposition of states) while also in two locations at once (the two boxes are entangled with one another).

And here it is in the Washington Post — maybe easier for some people to follow:

But they don’t know what state the pair of cats is in, until they sic Schrodinger’s dog on one of them and then the jig is up for both cats.

And a reminder that the universe is a construct that is very complex

Dunno, but I'm stealing the GIF:

Schrodinger hated the thing, actually. And I've always wondered - if it takes observation to collapse the wave function, wouldn't the cat suffice?

Lots of cute cat vids too. :)

I think that is the standard answer to the paradox. The cat itself is an observer.

Depends on what the definition of "observe," is.

If Schrödinger's cat is observed by a non sentient lifeform in a forest, does it's wave function collapse?

Two Boxes. Alive and Dead at the same time: Sounds more like the basis for a backup system that saves correctly exactly half of the time.

Another possibility is that I have no idea what I'm talking about.

So maybe the transgender thing isn’t such a big deal after all......

No. More like: things don't work the way you think they do.

“if it takes observation to collapse the wave function, wouldn’t the cat suffice?”

Well, maybe, maybe not. The wavefunction might collapse as far as the cat is concerned, but since the cat cannot communicate the information of what it observed to us, then the wavefunction shouldn’t collapse from our perspective. I think...

Then again, I don’t really buy the whole “observation collapses the wavefunction” argument. It may work as an ad hoc explanation for the phenomena, but I don’t think it’s going to prove to be the true cause in the end.

Indeed cats are VERY observant. The Egyptians knew cats are the earthly eyes and ears of the gods

Well, you know how in computing, everything is ones and zeroes at the most basic level? Those are binary “bits” of information, with 2 basic states, on or off. In quantum computers, the bits have 3 states, on, off, and both on AND off at the same time.

This development has basically entangled two of those bits so that if one bit is changed, the other bit will change instantaneously to the same state.

There was/is an old saying, “Garbage in, Garbage out”.

Next saying?

“Uncertainty in, Uncertainty out”.

Physicists....nothing better to do than dig around in cat boxes.
