Quantum Physics... Sorted!

We’ve all seen that tired old commercial of Reese’s Peanut Butter cup where someone with chocolate bumps into another with peanut butter and they say, “Hey you have chocolate in my peanut butter”.  Well, we would like to present this axiom in the Physics world, because many scientists are looking so intensely at their challenge, that they don’t raise their heads enough to see what the other guy is doing.

Hence for your scientific pleasure, we would like to present, “Hey you got your Entanglement in my Cradle”



Ingredient One – a puzzling physics phenomena for the better part of 70 years…


Quantum Entanglement is a property / state of a quantum mechanical system.  Which essentially means that any two quantum particles that are entangled 

(when two gamma photons with E=510,999 eV will collide they will produce positron and electron in pair production process

with each other behave as a "whole", even though they happen to be at the opposite ends of the universe, and the moment one of the particles' spin in determined the other particle's spin can be predicted as well. And if one of the particles' spin is reversed, then the other particle will instantaneously reverse its spin!!

However, Einstein realized that such instantaneous communication of polarization value between the two photons was forbidden by his own theory of Special Relativity (nothing travels faster than light). Hence, Einstein believed that the model of quantum mechanics was incomplete: it did not describe the physical reality of Bob's photon before observation.

Niels Bohr and Albert Einstein debating quantum theory in the mid 1920s
Einstein believed the correct way out of this paradox was to assume that Bob's photon (and all particles) possessed some sort of fixed properties which were hidden from our view (generally referred-to as hidden variables). No faster-than-light communication is then required: the particle properties were set when the particles were created. Crucially, though, this would mean the particles possessing more information than quantum theory said they should have. If particles had these hidden variables then quantum theory was wrong.

Now with that said, Ingredient Two…


A quantum Newton's cradle


The classical Newton's cradle involves a number of steel balls, usually five, suspended in a line by fine wires. If you set one ball swinging it hits the stationary balls and its momentum is transferred through each of them until exactly one ball at the opposite end swings away, the rest remaining stationary.

"The quantum Newton's cradle is just like a classical Newton's cradle, except that it's more perfectly one dimensional and instead of 5 balls there are hundreds," says David Weiss, leader of the research team. "Also, because it's a quantum system, the atoms often just go right through each other, which never happen with the executive desk toy. Another difference is that you can't buy the quantum Newton's cradle on the Internet."

Images of quantum Newton's cradles during their first cycle of oscillation. Each atom collides with half the other atoms twice each 13 ms cycle, sometimes bouncing off each other, sometimes passing through each other. The cartoon steel balls drawn at the top show the analogy between the quantum and classical Newton's cradle.

But the most exciting difference was that even after thousands of collisions, the movement of the atoms stayed the same. "A fascinating thing about this system is the remarkable stability of its momentum profile, which does not change even after each atom in the system has collided thousands of times," says Weiss. The movement of the particles never became chaotic. "We set all the atoms oscillating in the trap with almost the same amplitude. We found that even after each atom has bounced of the other atoms 10,000 times, each still oscillates with the original amplitude."

Usually the motion of many particle systems, such as gases, eventually becomes chaotic, reaching state physicists call thermal equilibrium. In this state all the parameters describing the system, such as temperature, are unchanging. However the system that Weiss and his team created never reaches this state, and instead a constant predictable motion was maintained by the atoms. The theoretical understanding about this type of system predicted that this non-chaotic behavior was possible, but the researchers were the first people to ever witness it.

OK... are we the only ones that see the correlation?  


Could in fact the instantaneous behavior of the inverse coupled pair be explained with Newton’s Cradle?

In other words, what if the plane of existence is a tightly mesh of connected molecules that when one atoms state is changed, the coupled pairing just feels the transferred energy like the cradle? So no real distance is traveled because its one big body of atoms.


Just say’n…   (Oh ya... and we said it first…)
