A new quantum computer solves a math problem in 15 minutes. That binary computers can never solve.

“Scientists used a new error correction method to encode 70 logical qubits and solve a problem that is intractable for classical computers. The quantum computation took about 15 minutes, while leading classical methods would require an impractical amount of time.

“Researchers have demonstrated a quantum computation that appears to exceed the practical capabilities of leading classical simulation methods while also addressing a longstanding problem: how to verify the result.”(ScitechDaily, Quantum Computer Solves a Problem in 15 Minutes That Classical Methods Can’t Practically Compute)

A quantum computer completed a difficult calculation in about 15 minutes, while leading classical simulation methods would require prohibitive amounts of time. Just as importantly, the experiment included a way to establish confidence that the quantum result was accurate.”(ScitechDaily, Quantum Computer Solves a Problem in 15 Minutes That Classical Methods Can’t Practically Compute)

“The system completed 2,415 logical two-qubit operations and 468 logical “T gates,” two measures of quantum circuit complexity. Encoding the circuit reduced the effective logical error rate to one tenth of the physical error rate, allowing the computation to maintain high fidelity despite the large number of operations.”(ScitechDaily, Quantum Computer Solves a Problem in 15 Minutes That Classical Methods Can’t Practically Compute)

There are two major problems in quantum computers. First is that. Nothing that another quantum computer can check or inspect the result. The other problem is. How to make sure a quantum computer gets the right answer. This means. The quantum computer may make many errors in the process. From the beginning of the formula. To the complete answer. The danger is that the system can get the right answer. But using the wrong methods. The danger is that. The control formula is made using binary computers. It can give the right answer. Or an answer that seems right. 

Even if a quantum computer makes mistakes. And. If a quantum computer works incorrectly. That can cause errors in extremely long calculations. That take years. If. A computer solves a problem in one year. Inspection takes another year. So, making an answer and proving it takes two years. And this is one problem. 

“Random circuit sampling (RCS) has long served as a benchmark for testing whether quantum computers can outperform classical systems. In this task, a quantum computer produces patterns so complicated that classical computers cannot efficiently recreate them.” (ScitechDaily, Quantum Computer Solves a Problem in 15 Minutes That Classical Methods Can’t Practically Compute)

A quantum computer solved a mathematical problem. That was impossible for binary computers in 15 minutes. This means that there are limits to quantum and binary systems. The binary system is faster and better. When. Calculations are easy and small. But when complexity in calculations grows. That turns. Quantum computers. More suitable. The big problem is how to detect errors in quantum systems. The only thing that can inspect calculations that are too complex for binary systems is another quantum computer. 

When a quantum computer inspects and tries to detect errors. 

This system calculates all calculations backward. That means that getting the answer takes 15 minutes. And confirming that answer takes another 15 minutes. This looks impressive. But there are many problems. The biggest problem is that the quantum computer. It follows similar laws as other computers.

Increasing calculation capacity. It provides resources for more complex simulations and modelling. So, researchers bring more complicated formulas to computers. Increasing computing power. That increases the complexity of formulas. 

When researchers want to make a simulation. To simulate gas flow. They search for what that gas flow does. And then they try to make a fractal that follows those routes. The same way. It is possible to create material simulations at the quantum level. This thing. It makes it possible. To create very high-accuracy simulations. Those simulations are needed to control those materials with extreme accuracy.

The world's first superconducting quantum heat engine is real.

“Artistic impression of a superconducting quantum heat engine. Credit: Heikka Valja / Aalto University”  (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

Finnish researchers have created the first quantum heat engine. “Researchers at Aalto University have built the first cyclic quantum heat engine inside a superconducting circuit. The device uses a qubit, the basic unit of quantum information, as its working substance and repeatedly drives it through heating, cooling, and energy conversion.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“Quantum heat engines have previously been demonstrated with systems including trapped ions, atomic gases, nuclear spins, and defects in diamonds. Superconducting circuits are especially important because they are already among the leading platforms for quantum computing, communication, and sensing. Until now, however, no experiment had completed a cyclic quantum heat engine using this technology.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“The immediate significance is not the amount of work generated, which is extraordinarily small. Instead, the experiment shows that heat can be deliberately controlled and converted inside the same type of circuitry used to build quantum processors.”(ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

Quantum engines are the miniaturized versions of nanotechnology. If those systems. They can put particle spin very fast. When particles spin in the cage. It pulls energy through that structure. That causes a quantum glow in that cage. Basically, a quantum engine; it’s similar to other engines. e It can use the magnetic field and IR radiation combination. To make transform radiation into motion. Those systems. They just transform wave movement. Or electromagnetism. Into kinetic energy. So, when the core in a quantum engine spins. That core binds energy into it. When its speed accelerates. When it slows. It delivers energy. 

“That capability may become valuable as quantum computers grow. Today’s superconducting machines depend on large numbers of microwave cables running between room-temperature electronics and processors kept at temperatures only a fraction of a degree above absolute zero. Each cable adds cost, occupies space, and can carry unwanted heat or noise into the system.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“The researchers are now working toward a fully autonomous version of the engine. One possible application would be reading the state of a qubit without sending a microwave signal from the cold processor to room temperature. Placing more control functions directly inside the cryogenic circuit could reduce the amount of external wiring required.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

The quantum engine that transforms infrared radiation into motion is a fascinating tool. 

This. Kind of system. It can transform all radiation types. Into another by using motion. The radiation. Like radio waves. Hits the quantum engine. It starts to move. And then. It transforms that movement into electricity. Then that electricity. It can be used. As an example, an X-ray system.

Quantum system. That transforms kinetic energy into motion. That thing can be the new tool for micrometeor and armour technology. If the system can transfer impact energy into rotating movement. That can turn a surface extremely hard. In stealth technology. That ability to transfer electromagnetic radiation into movement. Makes it possible to pull standing waves out from space between atoms. Those systems. 

This kind of system. They can feed energy to quantum computers. The system. That can transform radiation into motion. This can bring interesting ideas for energy sources. To the journeys to the edge of the solar system. The quantum engine that can turn minimal energy into motion is the thing. That could replace at least some of the RTG (Radio Thermal Generators). Used in long-distance space journeys. Or those systems. They can at least make the RTG power sources more effective. By benefiting from the temperature that those isotope generators deliver. 

Nano- and quantum technology that transforms heat into motion. That is the system. That can help to create more sustainable materials. That stand the heat. The idea is that those quantum systems. They can transfer heat energy from the shell of the spacecraft or airplane into a moving part. This turns infrared radiation into movement. And then that nano-. Or quantum generator. It can transform the heat into UV light. 

This kind of transformation is quite easy to make. The nanotechnical generator. It simply transforms heat energy into electricity. Then that electricity. It can be transferred to UV light. This kind of system. It can transform almost any wavelength into another. When things like radio waves hit this kind of system. That system can transform radio waves into X-rays through motion. This kind of system. They can be the next-generation tools. For new stealth  technology.

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.

A short tale about quantum computers

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.
