I came across the term 'Quantum Randomness' in another online discussion and was wondering what it actually was? Could anyone explain it to someone with a very sketchy knowledge of physics, if at all possible? Thanks!
avaxtasafi said:Thanks for that guys... but is it possible that we just haven't discovered what causes the particle to move north/south/etc.? Could there really be a cause behind this 'randomness' that we're not yet aware of? Or am I simplifying things?

caribou said:No, you're right. It is possible that what we think is random isn't actually random. Someone could come up with a theory behind the apparent randomness but it's just a lot simpler to just assume that it really is random.
Thanks for pointing the way to that paper! That was great!Rhizomorph said:Has anyone read C. S. Unnikrishnan's explanation for quantum correlations (http://arxiv.org/PS_cache/quant-ph/pdf/0001/0001112.pdf [Broken])? He's written a few papers on the matter and seems to have developed a convincing proof that such correlations can still be achieved with a local/hidden variables theory. But I've seen no recognition of his findings by anyone else.

Rhizomorph said:Wow, what sarcasm...
First of all, did you even read it? Second of all, saying something isn't convincing because the "experts" aren't paying attention to it is just, well, ignorant. He makes minimal assumptions (less than Bell, in fact) and his math is sound. So if you want to refute it, go for it (in fact, I'm looking for a refutation of it, that's why I asked about it) - but do so scientifically. Don't just say "oh well must be wrong because no one else talks about it." As for other papers he may or may not have "written" (as you insist on quoting), here are some in journals...

Rhizomorph said:Zz, does the lack of "expert" recognition of his paper mean you are unwilling to comment on it? Does anyone have any opinions?
Quantum randomness refers to the inherent unpredictability and uncertainty in the behavior of particles at the quantum level. It is a fundamental principle of quantum mechanics that states that certain properties of particles, such as their position and momentum, cannot be simultaneously known with certainty.
Quantum randomness is important because it plays a crucial role in many quantum phenomena, such as superposition and entanglement, which are essential for technologies like quantum computing and quantum encryption. Additionally, it challenges our understanding of determinism and causality in the universe.
Classical randomness, as seen in everyday life, is the result of a lack of information or knowledge about a system. On the other hand, quantum randomness is an inherent property of the quantum world, where even with complete knowledge of a system, the outcome of a measurement is still unpredictable.
Yes, quantum randomness can be harnessed for practical applications such as generating truly random numbers for cryptography and enhancing security in communication systems. It is also being explored for use in simulations, optimization problems, and machine learning.
While quantum randomness is unpredictable, it is still subject to the laws of quantum mechanics. This means that although the outcomes of individual measurements may seem random, there is still a level of underlying order and structure that can be described by mathematical equations.
