quantum entanglement & schrödinger's cat experiment

 

 quantum entanglement:


Before we go in-depth in general we have to know about exactly what the quantum entanglement stand for ,the concept says that ,in most basic level all particle connect or co- relate with each other ,but how it’s not possible reach any sharp conclusion .

lots n lots of assumption and  ways of describing entanglement, and there is no single definition that is universally accepted.

 But most people agree that entanglement is a unique state of consciousness, the sensation of sharing one experience with another person,And in a sense, each physical system is a local pair of entangled systems; we can associate two local variables of one system by giving them to one of the other.


In this interpretation, then, we use the term “entangled” to describe the unique way in which these two systems can be related.


For an example :quantum entanglement between two masses, A and B, do they remain distinct in terms of their physical properties mass and position ,In other words, what are the physical relationships between A and B that relate their states to each other, and hence make them different in some way? And what are the effects of changing the correlations between the states of “A” and “B” in a quantum computer…

 

quantum entanglement : term for what I’ve been calling open energy...

 

So, to get an explanation of this, I’ll be using the following abstracted definition: open energy is the amount of energy available for converting things to photons.

 

I have been calling this measure, also known as the efficient scale of open energy, the disorganized-unity, because to understand this, we need to know how to measure and calculate this. This way, we can compare photons to particles in the same way that we compare electric charges to magnetism and so on.

 

To measure open energy, we start by combining all the different measurements of photons—orbital angular momentum ,spatial coherence, temporal coherence, phase coherence, and so on…into one linear sum that tells us the energy of a particular photon.

 

A photon  then, is the sum of all the “energy states” of the quantum of a particular photon. And these states can be combined to define a larger number that tells us the actual energy of the photon. In fact, the change in energy in this calculation free orbital angular momentum, is the rest mass of the photon, is the energy of the photon, is the total angular momentum for all the other photon.


  photon was first emitted by the atom, and is the total amount of rest mass plus time that the photon has existed since its initial emission.

 schrödinger's cat experiment:


 

consider throwing a ball straight into the air can we  predict the motion of  the ball after it leaves our hand sure that's easy the ball will move upward until it gets to some highest point then
it'll come back down and land in your hand again of course that's what happens
and we know this because you have witnessed events like this countless times we've been observing it everyday phenomena of our  entire life.


the physics of the macroscopic objects we see around all the time  everyday world we know and love behaves according to the laws of classical mechanics but systems on the scale of
 according to the principle of
quantum theory this quantum world.


turns out to be a really strange place an illustration of quantum strangeness is
given by a famous thought experiment Schrodinger's cat a physicist  put a
cat during a box along side a bomb that has a 50% chance of berating after the lid is closed until we reopen the lid there is  no way of knowing either  the cat is alive or dead .


 we would say this before our observation the cat was in a superposition state it was neither alive nor dead , during a mix of both possibilities with a 50% chance for each the same sort of thing happens .


 physical systems at quantum scales like n electron orbiting in a hydrogen atom
the electron isn't really orbiting at all its sort of everywhere in space all at once with more of a probability of being at some places than others and it's only after we measure its position
that we will pinpoint where it's at that the moment a lot like how we didn't know whether the cat was alive or dead until we open the box this brings us to the strange and beautiful phenomenon of quantum entanglement suppose that instead of one cat during a box, we've two cats in two different boxes if we repeat the
schrödinger's cat experiment with the experiment can be one of four possibilities ,either both cats will be alive or both are going to be dead or one will be alive and the other dead or vice versa .


the system of both cats is again during a superposition state with each outcome having a 25% chance rather than 50% but here's the cool thing quantum mechanics tells us it's possible to erase both cats alive and both cat's dead outcomes from the superposition state.


 in other words there can be a two cat system such t outcome will always be one cat alive and the other cat dead the technical term for this is often that the states of the cats,
are entangled but there's something truly mind-blowing about quantum entanglement,
 system of two cats in boxes in this entangled position then we  move the boxes to opposite ends of the, universe the result of the experiment will  always be the same.
