Hmm. That's a cat alright, Clete Orris, but it isn't Schrödinger's cat.

Fuggin Bizzy: Hmm. That's a cat alright, Clete Orris, but it isn't Schrödinger's cat.


But it could be.

As someone who dressed as Erwin Schrodinger (complete with fully sealed cat box) for a science-themed party this past weekend, I may or may not be getting a kick out of these replies.

Just use a non-colorable critical set. QED.

I submit that it is, and it isn't. Prove me wrong.

QKD Works.

Here's a little video (new window) from the place I work at explaining it.

BTW, Toshiba may be researching it, but my workplace is at the forefront of QKD research.

The cat appears to be alive. Schrödinger's cat may or may not be alive - its state is unknown.

appearances can be deceiving. prove to me that the cat in the photo is alive.

Headline win.

It's only secure if you don't read the message. Up until then, it is secure.
 
2010-12-13 04:53:00 PM  
That is the best headline I've seen in a while. Thanks!

I might have submitted this with a better headline. Or maybe I didn't.

FTA:

Last week, researchers at Toshiba's Cambridge Research Laboratory published a summary of finding that showed that this attack and others are ineffective if the hardware is set up properly.

Well, there's your first mistake. There are plenty of classical hardware systems that could be considered "secure" if things are set up properly.

But yeah, this seems more like:

"We found a potential hack."

"Ok, here's a rebuttal."

That pattern is nothing new.

The nifty thing about quantum cryptography is that it promises a *mathematically provable* secure system.

The sucky thing about QC is that like anything else the devil is in the details; We have yet to match the promise with real systems.

Stuff like this helps though.

+1 for subby for actually understanding Quantum phenomena.

Frown on your shenanigans.
