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.

The 2D particles and Bloch wave function make it possible to create the 2D quantum processors.

The anyons could be the heart of the next-generation quantum computers. "Physicists are excited about anyons not only because their discovery confirms decades of theoretical work, but also for practical reasons. For example, anyons are at the heart of an effort by Microsoft to build a working quantum computer(1)".

Why anyons the two-dimension particles are interesting things? The thing is that anyons are 2D particles like pancakes. The anyon-particle can be used as the base for the new type of superconducting materials. If they connected with the Bloch wave function. The idea of superconducting is that electrons are forming pairs. 

The problem with the electron pairs is that. They are always on the opposite side of the nucleus of the atoms. So the most powerful superconducting material would be Helium. But that requires removing the nucleus of the atom from inside the electron cores. And also the position of the electrons in 3D structures is not stable. 

The electrons can be upside or downside of the nucleus. And that thing will cause the limits of the superconductivity. But what if electrons would put to orbit in one layer? That thing requires that the nucleus of the atom is replaced by using 2D particles. And the anyon could be suitable for that kind of purpose. 

The most effective superconducting wire is the electron chain. Those electrons must be stabilizing in the right position by pressing them with the magnetic field. That thing makes it possible to create the electron structure that can fundamental the computing. In that case, the positive magnetic field along with laser rays will push electrons to the chain.

"In the lower right, a near-IR laser separates the two electrons (empty circles) from the two kinds of holes (solid circles). The charges are accelerated away from each other by the fluctuating electric field from the terahertz laser (gray wave)".

"The changing field then drags the charges toward each other, at which point they combine and emit two flashes of light. The trajectories are depicted in one dimension of space. With time flowing from the bottom right to the top left". Credit: Brian Long(2) 

The diagram above introduces the Bloch wave function. That thing could also be the model of the 2D quantum processor. If the quantum processor has a 2D structure that allows stabilizing the vertical position of the qubit by using a magnetic field. The

The Bloch wave function makes it possible to create new and compact quantum computers. The anyons can be used to anchor the electrons in the core. That thing makes it possible to create a 2D quantum processor that is more powerful than any quantum system before. If the quantum system uses a 2D structure aiming the qubit to one port would be easier than in a 2D structure. 

The anyon can work as the center of the thing called Bloch wave function. The Bloch wave function requires that the electrons would be in the two-dimensional layer. And then the laser ray can separate the electron pair from the structure. The 2D particles can be used as an anchor that anchors the electrons in one layer. That thing makes it possible to make new and more powerful and more compact quantum computers.

Memory manipulation can be a tool. That removes bad memories.

But who makes the decision? What are bad memories?  The ability to select memories. It is a new thing. For. Psychotherapy. But those things ...
