Physicists have discovered a new method for stabilizing quantum chains using crystals.

“The nitrogen-vacancy center (N-V center or NV center) is one of numerous photoluminescent point defects in diamond. It consists of a nearest-neighbor pair of a nitrogen atom, which substitutes for a carbon atom, and a lattice vacancy.” (Wikipedia, Nitrogen-vacancy center)

“NV centers enable nanoscale measurements of magnetic and electric fields, temperature, and mechanical strain with improved precision. External perturbation sensitivity makes NV centers ideal for applications in biomedicine—such as single-molecule imaging and cellular process modeling.”(Wikipedia, Nitrogen-vacancy center)

“In crystallography, a vacancy is a type of point defect in a crystal where an atom is missing from one of the lattice sites. Crystals inherently possess imperfections, sometimes referred to as crystallographic defects.” (Wikipedia, Vacancy defect)

The image of Bravais lattices explains how electrons interact around the atom. There is, of course, a ball-shaped field around atoms, but between electrons. There is also a straight energy string. Those strings are energy flows that travel between those electrons. The atom’s shell pulls those electrons into it. And that keeps electrons and atoms. In one entirety. And the energy bridges between them, the electromagnetic push between negative electrons tries to push those electrons away. 




“The seven lattice systems and their Bravais lattices in three dimensions” (Wikipedia, Bravais lattice)


In natural diamonds, the NV centers form randomly. But. There is a possibility of creating artificial NV centers. And putting them in line. This allows information to travel through that line. Those NV centers can be used as the transmitters in the quantum radars. This means that the diamonds there have the NV state line in them. Those NV-states can be used in high-resolution quantum Doppler radars. The system transmits electricity to those NV states. And then they act as the transmitting dipoles. 

In the image above, a method is introduced for stabilizing the qubit chain in the diamonds. Qubits, or their nitrogen vacancy (NV) states, are chained in the diamond.  The diamond presses that qubit chain, and keeps it in form. When information is transported into the qubit’s transmitting side, it allows the wave to travel through those NV states. In a qubit chain, the qubits form an energy staircase. There, they can transport information. Step by step. The system can adjust energy levels on those stairs. Very accurately. This means that lasers can be used to transport energy into those NV states or NV steps. The system can transport information in the static NV-state system. 




“Simplified atomic structure of the NV center”. (Wikipedia, Nitrogen-vacancy center)


When we think of this system as the tool that transports qubits through air or quantum channels, we must remember that diamond can be used as a phonon. First, the system makes the phonon. That creates the acoustic tunnel through the air. Then the information is sent to the NV states. The NV states send that wave movement into the receiver, and there, the receiving NV state starts to resonate. Another version is that the diamond takes the one NV state to its sharpest point. The system can use the corners of the pyramid-shaped diamond. To make the energy tweezers that lock the ion in front of that NV state line. Then the qubit line stores information in that NV state. And the higher energy level in that system pushes the qubit through the quantum channel. These types of systems are very interesting. They can be used to transport information in a highly secure mode. 

“Natural NV centers are randomly oriented within a diamond crystal. Ion implantation techniques can enable their artificial creation in predetermined positions as follows.” (Wikipedia, Nitrogen-vacancy center)

“Nitrogen-vacancy centers are typically produced from single substitutional nitrogen centers (called C or P1 centers in diamond literature) by irradiation followed by annealing at temperatures above 700 °C. A wide range of high-energy particles is suitable for such irradiation, including electrons, protons, neutrons, ions, and gamma photons. Irradiation produces lattice vacancies, which are a part of NV centers. Those vacancies are immobile at room temperature, and annealing is required to move them. Single substitutional nitrogen produces strain in the diamond lattice; it therefore efficiently captures moving vacancies,[producing the NV centers.” (Wikipedia, Nitrogen-vacancy center)

The first programmable quantum computer is made by using neutral atoms.





The ability to use neutral atoms in quantum computers is a remarkable thing. Until now, quantum computers used trapped ions or superconductors in their structure. But the problem with those versions is that they are very sensitive against outside effects. If trapped ion touches the core of the chamber. Or the temperature of a superconductor is rising too high. That thing causes the problems. When we think about the possibility to make the room-temperature operating quantum computer. 

The researchers must "simply" calculate the resistance of the wire is possible to calculate precise points where the qubit reaches a certain state while it loses its energy. By using that information. The computers can calculate the points where qubits are releasing their information. So what if we want to make so-called quantum brains? What would we need for that? There is the possibility that the hybrid system is made by using a nanotechnological structure. The system's core would be made of silicon-carbon material where are chambers. 

Those chambers are connected as an entirety by using nano-tubes. In each chamber is the ion. That anneals by using radio waves or some other electromagnetic radiation.  The brightness of the ion is determining the state of the qubit. The annealing system will measure the brightness of the qubit by using the photovoltaic cells. In that system, the silicon core is also acting as the independent quantum computer. Which controls the quantum annealing system. 

Light is a good data transporter. If the brightness of the laser rays can adjust. That thing can use to transport data in quantum computers. The laser ray can shoot to silicon atoms. And that reaction can turn to electricity that can act as a qubit. The silicon atom-based quantum computers can get their data by using laser rays. And maybe those systems can operate at room temperature. 


The biological quantum computer is one futuristic vision of this system. 


The use of the biological components will decrease the need for energy in the quantum annealing system. 


If we are thinking about the most futuristic way to make the quantum annealing quantum computer. There is the possibility to use the biological components in this system. If we want to put the cells that are creating light in those chambers we could make the light. 

And then the brightness of the light can adjust by using the iris. So the core of that chamber would be equipped with systems that are looking like a camera shutter. And that shutter adjusts the brightness of the light. 

The problem with quantum annealing or other quantum systems is how to make the data travel in lines. The power of the quantum computer is this.  The system can share data with multiple central processing units. The idea is similar to the book that some school classes should read. There are two ways to make this thing. All members of the class are reading the entire book.

Or the teacher can share the book with all members of the team. And then every member of the team is reading small parts of the book. So the book is shared in pieces with team members. That means every person in the team will read only 10 pages from 200 pages of text. 

And after that, the members of the team will tell what happened during their 10 pages. That model is very good if the data mass that the system handles is linear. So the row of the data is like the book. And it will share between central processing units which are operating with a small piece of that data mass. 

When the system shares data there might be some top processor. That processor is like the teacher in the classroom. It preprocesses the data as the teacher looks at the number of pages in the book. And then the teacher asks, which part of the book the members of the team are taking. When the team members are ready. They send the mark that they are done their job. 

There is the possibility. That in the middle of the system is the light source. That shares data to the entirety. In that data flow is the marks where the system cuts it. Then every single part of the system tells others which part it takes to handle. 

It eliminates the work that has no meaning. The error handling requires that somewhere in the system that makes the similar data-handling processes. If those results are the same the solution is right. 

Then the rest of the others would select from the remaining pieces of data. That thing requires complicated structures. Human brains are the biological quantum computer. But to make a copy of human brains engineers must have at least 200 billion data handling units. And controlling those units is a very complicated mission. That requires multi-level quantum computers. And complicated AI.
