Two entangled black holes (cool horizons for entangled black holes)

+ 0 like - 4 dislike

I figured out how to pairwise entangle two spheres as in the paper by Malcedona, Susskind in that a single vortex wavewguide for a laser beam (two tubes joined along the length forming at a cross section a solid 2d horn toris, like two tubes joined to make a single tube in a hornet's nest). the waveguide splits and goes in two direction, but a picture is better.  Imagine taking the center solid up and down piece (hyperbolic in shape and narrowing to a point just below center at a cross section in the original waveguide), and splitting it, so two waveguides of the same type are going away from each other to two spheres.  The two beams are entangled as the laser is vortexed and the original vortex splits into two, forming two vortexed lasers continuously flowing from a single vortexed beam in the original waveguide.

In the paper, cool horizons for entangled black holes, the author states that alice and bob have entangled qbuits (pairwise), so a train of paired qubits.  The action of each black hole scrambles them, so that any subgroup of those qubits are now entangled, as shown in their paper.  So you if a and b are pairwise entangled, c and d are pairwise entangled, then a, b, c and a,b,c,d as two groups are entangled.  The vortex laser acts like a flame in that there is a central tight vortexed beam flowing down just below midpoint of a waveguide, that splits into two spheres, with condensed matter..  Many such waveugides are directed at the two spheres, the waveugide splitting in two and entering two spheres with condensate, and laserbeams at both spheres directed at the center of each sphere.  I've already shown how this would generate an array of tori in the sphere that the vortexed beam randomly flows through, lighting the ones it does in a dyed condensate, and the ones it doesn't remain dark.  The randomizer condition is satisfied, as it was a necessary condition for the two qubits, here two vortex beams, to become randomized with other pairwise entangled qubits, in bob's A sphere, and alice's B sphere, that results in large entangled groupings, as any subgroup of the qubits, from first pick a number of them from A, and a number of them from B, they will be entangled if they are a subgroup of the pairwise entangled train that enter each sphere.  The beam splitting entangles the two new beams with each other.

Closed as per community consensus as the post is not a real question

Not a real question, voting to close. 500+ rep users can help getting it closed by upvoting the closevote there.

Also, you have already been told that PhysicsOverflow is not for posting long essays that would belong in a personal blog or even look as if created by feeding an automated text writer with some physics keywords. Pleases stop this, this is your second warning.

If the beams are instead beamed parallel to the surface of the sphere, through ports, covered by a one way mirror, the beams would cross in a hatchwork like a chain link fence.  Looking at particle wave theory, where the beams cross, the photons would build up first in a circle there, and then in a vortexed torus.  It would be twisting like that since the original beam isvortexed.  At all crossings in the hatchwork (inside surface of sphere is mirrored), of crossing beams, there would be a vrotexed torus at the crossing, which will build another level, that spirals in vortexed fashion (although locally it looks like 3d stacks) of same size tori, and at the center would be a ball of light.  I'm not sure what you have issue with.  The single laser beam splits among two spheres, with condensed light in waveguides and sphere due to a dye that phosphoresces and thermally extracts energy from the light condensing the light,  When it splits as described, the two beams are entangled.  Did you read any part of Malcadena's paper?  There would be manyh such beams splitting, into the two spheres, each entangled.  The random action of the black hole, or here random flow of vortexed light through vortexed tori, is the randomizer that is spoken of in the paper, which shows now, instead of pairwise qubits, andy subgroup of the entire set of pairs is entangled.  That's what was shown in the paper.  The point is that that would allow for entangled computation.  This is also what happens when water splashes randomly on a piece of paper.  It forms on the 2d surface of the paper, distinct channels where the water flows, in a chain link fence pattern of the channels.  The  splash of water on a hard surface looks like a spiderweb of pointy and concave areas between pointy areas.  In this example of how the light flows, that would imply something from the center of the sphere splashing on the surface of the sphere, or a reverse splash to the center of the sphere at a condensed ball.

Actually if you fire into the sphere, with many beams directly at the center, you'd have it.  Each beam would be covered by a one way mirror so the light can flow into the sphere but not out.  The beams would bounce off opposing walls, and because the beam is vortexed does create a splash similar to water.

PhysicsOverflow is not for posting personal non-mainstream ideas that would belong in a personal blog. This is your fourth and last warning. One more similar post and your IP address will be blocked.
