Noise is the problem with quantum systems.

Above is Maurits Escher’s drawing Ascending and Descending. The drawing. It could portray the quantum system model. There is a quantum circuit where information travels. And the trunk. That mission is to deny the noise. The trunk is the cooling system that surrounds the quantum circuit. Because. In a quantum system, information travels in quantum entanglement from a higher energy quantum dot to a lower energy quantum dot. This means the quantum circuit is like a tower. 

The main problem. With quantum systems, the transmitting side in the quantum entanglement must be at a higher energy level than the receiver. That means it’s hard to make a closed quantum circuit that surrounds data. Every time data travels around the system, the last particle pulls the energy level in the system higher. 

Another problem is that. When the system processes information, it must bring information from other systems. This means that the other system must be at a higher energy level than the receiving system. But. Information rides in an energy beam, and that thing raises energy in the system. The free energy is the thing that destroys the quantum system. We can call this thing: “The last particle in the line problem”. When information reaches the last particle. The system must rise. The last particle’s energy level. Higher than the first particle. Energy level is. Or the last particle must transfer information to the hard disk. Then the system can adjust the quantum system again. 

Another solution can be the photons that are anchored around the laser beams. The photon is like a ring around that laser beam. The laser transmits information to the photon. Those laser beams also transport energy away from those photons. And that can keep their temperature stable. The important thing. It is to keep receiving particles at a lower energy level than transmitting particles. 

Information travels in the system between quantum points. The problem with quantum systems is the “noise.” The noise is free energy. In the system. Free energy forms because of the quantum field or glow that surrounds every quantum dot. When a quantum dot. Like a photon in quantum entanglement, the dot in a higher energy level transmits data to the quantum dot in a lower energy level. The information travels in the string, and when that wave movement reaches the receiver. 

It forms a flash in the quantum field. Or, the glow that surrounds the quantum dot. That flash transfers energy to the trunk. That causes oscillation in the groove that holds the quantum dot. Each quantum dot is like a light bulb. It shines energy. And that’s why those quantum dots cannot transfer all energy between each other. Lots of energy that carries information just travels into empty space in the quantum circuit.

The noise forms when energy in the system is rising. Data is traveling in the quantum circuit between superpositioned and entangled particles. The transmitting particle must be at a higher level than the receiving particle. The reason why the quantum system is so sensitive to noise is that all quantum dots are identical. Except that their energy level is different. This causes a situation where every oscillation escalates through the entire system. Because all of those particles have different energy levels, which causes the situation. Where those particles’ sizes are different. Because the transmitting particle’s size is a larger part of the energy, or information that travels between those quantum dots, it travels past the receiver. And that is one thing that forms free energy. 

Especially in the closed quantum circuit, data travels in a circle, and the system must raise the energy level within the circuit. The problem is in the cases. Where information reaches the last particle in the quantum system. Then the last particle must send information back to the first particle. So, the system must raise the last particle’s energy level over the first particle. And that means the system must raise the energy level in the entire system. The noise is another term for free energy in the quantum system. Free energy or entropy form. 

Because. Quantum entanglement cannot transmit 100% of energy to the receiver. The energy that travels between those quantum dots or particles affects the quantum glow around the particle. That glow transfers energy or wave movement between those particles and the trunk of the system. The energy level in the system. Cannot rise endlessly. If the energy in the quantum glow rises too high. That energy destroys the entire system.

A short tale about quantum computers

https://gamesandtehories.blogspot.com/

Kimmo Huosionmaa

Biggest and the most difficult problems of creating the quantum computer are to make a processor, what can make real multitasking and making the command language for that thing. The idea of the regular computer is that it would use binary numbers one and zero for making its tasks. Use of those numbers is very simple. Number one is the thing when there is voltage in the wire, and zero is the situation that the wire inside the processor is without electricity.

The binary system, what is used in computers is the thing what is created by mathematicians like Johan von Neumann, for ENIAC computer. And after that, every single computer have used that kind of architecture. If there would be another programming architecture the computer would not able to handle the data, that is stored in the elder databases. If the system what is using zero and one would be replaced by some other would the elder databases become useless, and storing that data again is a very hard process.

Also, the system what would replace the binary code in processors is hard to create. But if there would be a regular computer as the translator for the commands, what would give to the quantum computer, that would make the dream true. There would be many problems with the screens, and how they handle the data, what comes from the quantum computer. The most difficult thing would be, that the output device will be slow, and the quantum computer is very fast in comparison with regular computers. The technology, what is planned to use in the production of quantum processor would make possible to create a compact computer, what can be installed in human-size robots.

The real life that means that the regular processor can make only one task per operand, what makes it very slow when we are handling very big databases. When we are thinking about multitasking in the operating systems like Windows there is one thing that has ever mentioned. The multitasking in those operating systems is virtual, what means that we can, of course, open many programs at the same time to screen, but the processor would handle them by one by one.

In the Windows that is done by the way, that the program would leave handler in the memory of the computer, and if the window is open, will the code of program very easy to find from memory. This means when the user uses another program, would the unused program remove most of its code from the memory, and a small part of it would leave as the trigger in the memory, and the user can activate the program by clicking the icon or window of the program. If the processor would be the quantum processor, those programs can run in real mode.

When we are thinking that some calculations would be done backward with a regular computer, that means the computer would switch between programs and calculation. Modern computers are very fast,  and that thing would not disturb anybody until the needed calculations are on a very massive scale. When computer calculates extreme long series like prime numbers by using Riemann's conjecture would there need to calculate billions of numbers.

And in that kind of cases, the calculation power of the modern computers would not be enough. If the computer would be cooled in the superconducting temperature, would that make it faster, but the thing what is needed is the real multitasking. The quantum computer would give the mathematicians ability to create extremely large simulations, and that gives also the ability to drive extremely large databases at very high speed, in the real world the system what uses real multitasking have been tried to make by creating processors, where is installed multiple processors in the structure, and that is called multi-core processor. Quantum processor would be used by using another computer, and in that case, the normal computer would translate the commands to the quantum processor. And that would be making that computer real thing.
