The image above introduces a situation. The wave movement impacts a photon. That thing makes the photon oscillate and send a wave movement. That thing can also split a photon into two pieces. When a photon travels in a quantum network. Transporting information. The system must store information about that photon. 

And after that, the system must also download information from that photon. The very thin wave bites could act like the needle of the gramophone. The system scans the depth of the waves that are on the photon’s surface. The quantum system stores information in those waves. And the number of waves determines how many states the qubit can have. Another determinant is the depth of those waves. 

Researchers at the University of Tampere split a photon into two photons. That thing proved that even photons follow one of the basic rules in physics: the conservation of angular momentum. So, if the system can make photons act like a gyroscope. And keep those photons in the same position, which makes a new advance in photonics and quantum computing. A series of superpositioned and entangled photons can transport information in nanotube-based systems.

Splitting a photon into two photons by aiming a laser beam, or a wave movement through it. It is one of the things that can make quantum networks closer to reality. In a quantum network, information is stored in particles, like photons.  In a quantum network, particles travel and transport information. In a regular network, wave movement acts as an information transporter. 

The problem with the quantum network is this. Those particles that travel in that network. Should not touch anything unexpected. Any field or unexpected error in the quantum network causes a situation. There is information that particle transport can be damaged. The problem with error detection is this. The system cannot detect errors that happen in some quantum line. 

The answer for error detection is to send information using two separate lines. If those lines create identical solutions, the answer is ” probably closer, right than wrong”. In reasonable circuits. The system makes all calculations backward. And if the answer is the original values, the system gives the right answer. But if the system transports information into two lines, it must split that thing into two routes. 

In a quantum network. That requires that the system must create two identical information packs. So, the ability to split photons can be a tool for quantum routers. But the system can use this technology in quantum computers. Splitting photons and putting them into superposition and quantum entanglement is one thing that can make the quantum chips closer to everyday reality. The information that photon also follows the principle of angular momentum is the thing. That can be important for quantum technology. If the system knows when photons “fall” in quantum entanglement, that can improve the quantum system's effectiveness.

The new quantum gravity model takes us closer to the Theory of everything, TOE.

The question of the form of gravity is interesting. Gravity is the only known force that affects light. And that makes it special. Another thing is that gravity seems to have no pushing force. This is the thing that makes gravity interesting. If we think that all particles have gravity fields and all objects like planets are entireties of those particles that means that gravity fields are the sum of those particle's gravity fields. 

Every particle is the quantum dot or quantum gravity center. The reason why the Earth-size black hole has a stronger gravity field than Earth is that there are more quantum dots in the same size object than the planet. So, the black hole can form around the structure of the quantum dots that are very close or melted together. The thing that determines the power of gravity fields is the density of those quantum gravity dots. So, we can turn any object into a black hole by pushing those quantum gravity dots together. 

That means if we think about the Theory of everything, TOE, we can make the model where the distance of those quantum dots determines which of fundamental interactions, Strong- and weak nuclear forces, electromagnetism, or gravity be in case. We can make a model where the superstrings of the extremely thin energy tube travel through those quantum gravity points. Those strings could be extremely small wormholes can also be one of the reasons why gravity acts as it acts. If something goes and cuts those strings they start to pull those things through them. 

The idea of the wormholes is that they must be extremely long and that the energy that travels through them can keep them open. The extremely long wormhole makes things travel in time. The expansion of the universe makes the other end of that energy tube a so high-energy level that the future has a lower energy field that can pull information through it. The information flow must be so strong that the outside energy cannot press that energy tube together. 

Finnish researchers from Allto University made models that should connect quantum field theory and Einstein's theory of relativity. That thing is the great step to the Theory of Everything, TOE. This model is interesting and those researchers published that in their publishings. You can find that thing in the article that is lined below this text. One of the most interesting questions of the gravity and its special nature is this: 

Can there be two or maybe three forms of gravity? 

1) Gravity that has the field effect. In that case, gravity is the field that travels into the gravity center. The gravity center or spinning particles can bind those fields inside them. And that means the system rolls those fields inside them. The field is like a river that takes everything with it. 

2) Gravity might also have a wave effect. That means gravity waves can have the shape that makes objects fall to the gravity center. And if there is a step, or false vacuum before the bottom of the gravity wave that makes objects fall to the gravity center, like I just wrote. 

The idea is that the gravity waves are at lower energy levels or they are deeper if the observer goes closer to the gravity center. The reason for that can be a similar phenomenon with the false vacuum decay. Or the gravity wave can stretch which makes it lower. That tells why outcoming energy that tries to fill the gravity wave is like a ditch that pushes particles into the gravity center. 

There might be a limit. Or the increasing mass turns the gravity waves less dominant than the field. The small mass objects can send gravity waves, but when those object's mass is rising that field pulling turns more dominating. The high-mass object simply rotates or binds a quantum field around it like dough. But does that thing cause only because massive object sends gravity waves so often? 

The last model that we can mention is virtual gravity. In some versions things like electromagnetism cause the virtual gravity effect. But another version of the virtual gravity is the particle the upper side has a higher energy level than the bottom. If that particle starts to rotate like wing gear. That was used in some early steamships. The idea is that the particle gets energy from up. And if it rotates horizontally that thing forms the energy wave below the particle. That energy wave pushes that particle forward.
