Comparison of computing power between quantum computer and brain

1.

According to reports, quantum computing is a way of computing system (quantum computer) to calculate data based on quantum, such as superposition and entanglement. The basic principle is to use qubits as the basic unit of information coding and storage, and complete the computing task through the controlled evolution of a large number of qubits. Compared with the traditional equipment, the computing power of quantum computer will increase exponentially

with the improvement of software - the more you can do with quantum computer, more resources will flow into this field. Assuming that one qubit can perform two calculations at the same time, two qubits can perform four times, three qubits can perform eight times... It will proce a doubling speed. Thirty qubits is enough to perform more than one billion calculations at the same time

netizens have expressed their expectation that the quantum computer can be completed as soon as possible

2. With the further acceleration of China's reform and opening up, China is graally becoming the base of global manufacturing instry. Especially after China's entry into WTO, the mold instry, as the basis of manufacturing instry, has developed rapidly in recent years. Mold is the basic process equipment of instrial proction. In electronics, automobiles, motors, electrical appliances, instruments, home appliances and communication procts, 60% - 80% of the parts are formed by mold. The five pillar instries of the national economy, namely machinery, electronics, automobile, petrochemical and construction, all require the development of mold instry to adapt to it. Mold is a "benefit amplifier". The value of the final proct proced by mold is often dozens of times or hundreds of times of the value of mold itself. The level of mold proction has become an important symbol to measure the level of a country's proct manufacturing, which determines the proct quality, efficiency and new proct development ability to a large extent. Therefore, in order to develop China from a big manufacturing country to a powerful manufacturing country, we must revitalize and develop China's mold instry and improve the overall technical level of mold instry. At the same time, the development of mold instry has been paid more and more attention. The "decision on the key points of current instrial policy" issued by the State Council also listed the mold as the first in the sequence of mechanical instry transformation and the second in the sequence of proction and capital construction

with the continuous development of advanced manufacturing technologies such as CAD / CAM software processing and rapid prototyping, as well as the popularization and application of these technologies in the mold instry, a profound technological revolution is taking place in the field of mold design and manufacturing. The traditional two-dimensional design and analog processing methods are graally replaced by the digital manufacturing methods based on the three-dimensional digital definition of procts. In this technological revolution, it is the key to master the use of CAD / CAM software and apply it to the digital design and manufacturing of die. The development prospect of China's mould instry is very broad. Domestic and foreign mold and mold processing equipment manufacturers are generally optimistic about the Chinese market. With the continuous improvement of mold design quality and manufacturing requirements, and the large-scale promotion and application of CAD / CAM technology in mold manufacturing instry, a large number of mold design and manufacturing technical personnel who are familiar with the application of CAD / CAM technology are urgently needed. This is not only the most valuable wealth of an enterprise, but also the most fundamental foundation for an enterprise to go to the world and improve its proct competitiveness. At present, there is a lack of professionals in this field

it is understood that in the current severe employment situation, the supply of CAD / CAM Technical Talents in China's manufacturing instry is not in demand. November 1, 2005 "mold workers are extremely short, you might as well have a try" article reported: "the reporter learned from the Guangzhou Municipal Labor Department that at present, the mold instry scale in the Pearl River Delta region accounts for about 1 / 3 of the country, but the mold workers gap has exceeded 100000. Mold instry is one of the main instries of machinery manufacturing, and it is also a major instry that the State encourages foreign investment. With the transfer of manufacturing center to China after China's accession to WTO, the mold instry is expected to usher in 30% growth. " Guangdong mold instry association pointed out that there are more than 60000 mold enterprises in Guangdong Province, and there is a great demand for mold professionals, especially senior mold professionals. In 2005, the monthly salary of mold senior class graates reached more than 3000 yuan. After working for several years, it was no problem that the monthly salary rose to 8000 yuan.

3. In fact, the human brain must be smarter and more flexible without quantum computer
because the computer is developed by human beings after all
it has faster reaction speed than human beings
because there are more calculations behind it

4. This is normal, because some people don't use their brains, some people use their brains

1、 Biological computer

advantages:

1, small size, high efficiency

The area of biological computer can accommodate hundreds of millions of circuits, which is hundreds of times higher than the current electronic computer. At the same time, biological computer, no longer has the shape of a computer, can be hidden in the corner of the table, wall or floor and other places, while the heating and electromagnetic interference are greatly reced

2. Permanence and reliability of biochip

biological computer has permanence and high reliability. If the repair mechanism of organism can be brought into play, the chip can repair itself even if it fails

(this is an extremely attractive potential advantage of biological computer) protein molecules can self assemble, and can generate new micro circuits with activity, so biological computer has biological characteristics

the biological computer is no longer like the electronic computer, which can not automatically repair the damaged chip. The biological computer can play a biological regulatory function and automatically repair the damaged chip

The storage and parallel processing of biological computer

Compared with traditional electronic computers, biological computers have great advantages in storage. One gram of DNA can store the same amount of information as one trillion CDs, and the storage density is 100 billion to 100 billion times that of disk memory

biological computer also has super parallel processing ability, through a narrow area of biochemical reaction can realize logic operation, tens of billions of DNA molecules constitute a large number of DNA computer parallel operation

Fever and signal interference

the components of biological computer are biochemical components composed of organic molecules, which work by chemical reaction, so they can be divided into two parts; It only takes a little energy to work

therefore, unlike the electronic computer, the body will not heat up after working for a period of time, and there is no signal interference between the circuits of the biological computer

5. Data error rate

Another important property of

DNA strand is the double helix structure. A and t bases, C and G bases form base pairs. Each DNA sequence has a complementary sequence. This complementarity is the unique advantage of biological computer

if the error occurs in a DNA double helix sequence, the modifying enzyme can refer to the complementary sequence to repair the error

disadvantages:

1. It is difficult for biological computer to extract information from it. A biological computer can complete all the computation of human beings in 24 hours, but it takes a week to extract a piece of information from it. This is also the main reason why biological computers are not popular

Second, quantum computer

advantages:

1. Quantum computer has powerful quantum information processing ability. For the current changeable information, it can extract effective information for processing, making it a new useful information

using this method can accurately predict the weather conditions. At present, the accuracy rate of the weather conditions predicted by the computer is 75%, but using the quantum computer to predict the weather conditions can further increase the accuracy rate, which is more convenient for people to travel

Because of the non clonable quantum principle of quantum computer, these problems will not exist. When users use quantum computer, they can safely access the Internet without fear of personal information leakage

Quantum computer has powerful computing power and can analyze a large number of different data at the same time, so it can accurately analyze the financial trend and play a great role in avoiding financial crisis

It can also play a great role in biochemical research, which can simulate the composition of new drugs and develop drugs and chemical procts more accurately, so as to ensure the cost of drugs and drug properties

disadvantages:

1, quantum decoherence

The coherence of quantum computing is the essence of quantum parallel computing, but in practice, qubits will be affected by the external environment, resulting in quantum entanglement

quantum coherence is easily disturbed by quantum entanglement, which leads to the decrease of quantum coherence, which is called decoherence phenomenon

2. Quantum entanglement

As the smallest particle, the

quantum obeys the law of quantum entanglement. Even in space, the quantum may be separated, but the interaction between the quantum is inevitable

3. Quantum parallel computing

quantum computer's unique parallel computing is an important point that classical computer can't match. It is also an n-bit memory. There is only one result stored in classical computer

4

quantum non clonability means that there is no plication process for any unknown quantum state. Since there is no quantum measurement to keep the quantum state unchanged, it is impossible to achieve plication. For quantum computer, it is impossible to realize the error correction application and function of classical computer

6. Human body is a holographic agent open to the environment and space; If we regard human brain as a biological quantum computer or something, it's too childish - the depth of understanding of this view is not as deep as that of yoga, nor as deep as that of Chinese "comprehensive and learning" Apocalypse of traditional Chinese medicine
human body (including animal ontology) is actually a holographic ordered agent composed of three internal and external levels and twelve systems. In this ordered agent, the human brain actually acts as the CPU of the computer, that is, the biological holographic processing system. The holographic memory function of hard disk is mainly composed of cardiovascular system. Therefore, the ancient Chinese recognition of "mind to mind", more accurately point out the function.

7. The human brain is a quantum computer, which is a phenomenon called quantum decoherence
to build a functioning quantum computer, we need to connect qubits, which can store a lot of information. This process is called quantum entanglement. But the entangled quantum is in a very fragile state. They have to be careful to avoid any interference from their surroundings. In a quantum system, as long as one photon touches the qubit, it is enough to make the whole system dissipate, and the quantum state will "decoherence" into an ordinary state, and the information stored in the quantum state will be lost and dissipated in the surrounding environment. Quantum processing in a strictly controlled laboratory environment is already challenging, not to mention that in a warm, humid brain, it's almost impossible to maintain coherent state when the molecules are dangling and crowded like a pot of hot soup.

8. Conclusion: the brain can be simulated by quantum computer
classical computers can't simulate the brain. One is the limitation of computing power. For example, even if a large database is built, it takes quite a long time to search for content. Second, the principle determines that it can not proce real randomness
quantum computer can solve these two problems well
however, e to the current cognition of consciousness, even if we use quantum computer to simulate the brain, we may not be able to manipulate and simulate the brain.

9. The so-called photonic computer is the logic processing process proced in the process of light conction. Practice has proved that it is feasible to analyze and process the logic signal of light. The advantages are fast processing speed, long service life, low power consumption and not easy to damage. The disadvantages are complex manufacturing and high cost
quantum computer is a special kind of computer, which is only used in a special situation. It is essentially the same as photon computer. It is mainly used in the strict processing computer of confidentiality and encryption, which has advantages, but its disadvantages are that it has no great advantages in general use, and there is no need to make it complex, so it does not use quantum computer in general
biological computer is the computer of model human brain, which is constantly inefficient and complex to manufacture, but has no advantages in coding and use. It is mainly used for scientific research, and it is needed for the research of brain medicine, which is used for model brain. The computing speed is the slowest
the above three kinds of computers, mainly each computer has its own role, and cannot replace each other.

10. The realization of quantum computer needs to construct the physical system of quantum entanglement, which still has a long way to go. Human brain can carry out parallel operation, and human consciousness is quantized, which is my guess. If this conjecture is correct, then in fact the human brain is a running & quot; Intelligence & quot; The quantum computer. Based on this logic, the study of human brain and consciousness is also very promising. Maybe we just didn't find the right way to run the brain.
