If you're flummoxed by this, you're not alone!

According to the weird rules of quantum mechanics, until a measurement is performed on a quantum particle, the property being measured has no definite value; measuring snaps the particle into a definite state, but that state is drawn randomly from a probability distribution of possible states.

I just read the whole thing. Not only am I now dumber than when I started, it hurt, too. -Wb

Well ? Don't just stand there, help the little fella up !

Whew!

I’ll sleep much better now....

This has had me concerned for some time!

I always thought an “interactive proof” was the hangover you got from mixing your drinks the night before.....

[American in Israel]

So, how do you find an unentangled particle if they are undefined to start with and the possibility of an entanglement is also unknown. All particles are interacting, and therefore entangled.

Or in otherwords, when talking Quantam Physics, vs Physics, is the same as Political Correctness vs just being Correct.

This is a big step in cryptography. If this can be practically implemented in security appliances, it could prevent DDoS attacks by requiring something akin to modern-day Captchas but by preventing automated attacks vs. attacks by a human or someone/thing that could attempt to subvert the cryptography.

For instance, modern day captchas use numbers and letters with random colors, pictures, etc. in the frame. This sort of cryptography would require plotting against questions that have yet to be asked, and that sort of thing could be required in multi-factor authentication schemes for computer logins, access to facilities, and the like.

It essentially invalidates guessing or “cheating” by pre-formulation of answers utilizing questions that aren’t yet put forward but could be guessed if the respondent already knew.

Okay, now my brain hurts.

It’s also something of a surprise, because when the question was first posed, it was immediately clear that some multiprover proofs were not resilient against entanglement.

well. duh.

I am a computer geek. I love computers. They have been the wellspring of my livelihood for decades. I hold many, many computer related certifications, and I really know my stuff.

This made no sense to me at all!
