Quantum systems and Entanglement

-  1828  -  Quantum systems and Entanglement.  How to connect the smallest particles in the Quantum World to the macro-world math that uses General Relativity?  Is the entire Universe a space-time fabric interconnected in this way?
-
-----------------  -  1828  -  Quantum systems and Entanglement. 
-
-  At the quantum level , when you deal with the size of atoms and smaller particles they do not behave as the sum of the parts.  Instead quantum particles take on a collective behavior.
-
-  Science is reduced to rough approximations when dealing with these quantum particles. Atoms do not have predetermined positions.  They are located at all possible positions at the same time.  They take fixed positions only the instant they are measured ( called the Uncertainty Principle).  The result is completely random at the same time at the quantum level they are somehow physically connected.
-
-  To deal with this, science is reduced to “ probabilities”  To specify a position there is a probability highest at the center of a “ cloud” and gradually diminishes towards the outer fringes of the cloud.
-
-  Then “ quantum entanglement” makes the math extremely complicated.  First calculate the probability of the first particle being measured on a certain position.  The position of the second particle depends on the position of the first particle .  The third particle depends on the positions of the first two.  And, so on……..  The correlations depend on the position of all the previous particle positions. 
-
-  The result for many, many particles become  “ quantum waves”.
-
-  The creation of these states of entanglement normally requires temperatures close to absolute zero and the application of enormously powerful magnetic fields.  ( called Bose-Einstein Condensations).  The temperatures are -270 C and the magnetic fields 1,000 times greater than everyday permanent magnets.
-
-  However, recent science has achieved entangled states on a semiconductor chip at room temperatures and using small magnetic fields.
-
-  When  photons are entangled they interact physically,  then forced to separate with the spin direction of one opposite to the spin direction of the other.  No matter how far the entangled particles are separated switching the spin of one immediately and instantaneously reverses the spin of the other.  The communication between the two entangled particles occurs faster than the speed of light.
-
-  Normally room temperatures mean thermodynamic entropy and chaos at the atomic levels.  It should be difficult to get entanglement in this completely disordered state at the atomic level. 
-
-  Normally, to get an ordered state very high energy photons from a laser are passed through a non-linear crystal.  The result at the output is a single high-energy photon that can be split into two entangled lower energy photons.  The two photons have entangled opposing spin polarizations because there were spawned from a single particle.
-
-  To achieve this same entangled state at room temperature a whole new approach is needed.  An infrared laser is used to align the magnetic states of many electrons and positive charged nuclei.  Then, entanglement is achieved applying short electromagnetic pulses,  (like magnetic resonance imaging, MRI).  The process occurs on a silicon carbide semiconductor.  The volume of entangled particles is about the size of a red blood cell.
-
-  This achievement in attaining entangled states repeatedly and economically has enormous potential in an endless number of applications.  Including:  biomedical, secure encrypted communications, information processing, high capacity data transfer, GPS satellites, and still more to be thought of………………
-
-  It all is to come from understanding “ entanglement”.   Entanglement concerns tiny particles that contribute insignificantly to gravity.  But, could there be a link to space-time that is governed by gravity and linked to the Universe as a whole?  If space has some underlying physics it may include entangled particles inherently.
-
-  Science is even going to Blackholes to study this possibility.  Inside and outside the Blackhole entangled particles might be connected by “ wormholes”.  Wormholes could be the bridge linking distant points in space.  They are hypothetical tunnels through hyperspace connecting distant separations in space.
-
-  This idea has been expanded to view the entire Universe as a quantum computer encoding space-time as a web of entanglement.
-
-  This idea is rooted in the math for holograms - the boundary enclosing a volume of space that contains all the same information contained in the inside of that space.   The 2-dimensional boundary has all the information contained in the 3-dimensional space inside.
-
-  Add to this 3-dimensional space a 4th dimension of time with space expanding at an ever increasing rate.  Quantum Mechanics math describes the boundary at the micro-scale.  Gravity and General Relativity describe the space inside.  The 2 entities share no obvious relationship yet they may be connected with entanglement.
-
-  Does entanglement tie space - time together?
-
-  Is space really entangled particles that flash in and out of existence too quickly to ever be measured?
-
-  Stephen Hawking’s idea is that Blackholes evaporate with entangled particles getting separated at the Event Horizon.  Then, all the information evaporating is the same as all the information contained inside the Blackhole.  Information is never lost.  The Conservation of Energy and Information can never be destroyed.
-
-  Is the Event Horizon of a Blackhole actually a holographic boundary?
-
-  Do all the entangled particles that escape the Blackhole remain connected to their counterpart inside the Blackhole via wormholes, tunnels in space-time.?
-
-  Is the entire Universe a space-time fabric interconnected in this way?
-
-  Could the ideas mold into one theory for Quantum Mechanics and General Relativity?
-
-  If we merge the enormous big and the infinitesimal small does that take us back to the Big Bang and the birth of the Universe.  God only knows.
-
-  Stay tuned, an announcement will be made shortly.
