1. One of the key technologies of digital currency is elliptic curve encryption, which is the core technology of digital signature of cryptocurrency. It can ensure the ownership, non plication and transaction integrity of cryptocurrency. But with the advent of quantum computers, it will no longer be secure. The quantum attack of quantum computer can solve the underlying mathematical problems, and the digital signature based on elliptic curve encryption can be forged. This is fatal for cryptocurrency, because the records of distributed ledger can not be tampered with and reversed. If elliptic curve encryption can be broken, then the security foundation of cryptocurrency will no longer exist.
2. Cloud quantum coin is a compound interest disk, in fact, there is no value, it is just speculation. At the same time, compound offer is also known as the four typical Ponzi schemes. There is no relationship between quantum coin and quantum satellite. This trick is too bad
if you are interested in digital currency, it is suggested that you pay more attention to bitcoin, Leyte, decent, Ethereum and other mainstream digital currencies.

3. Buy a computer, quantum computing digital currency, in fact, you need to have a certain understanding before you decide
4. On the afternoon of October 16, the Political Bureau of the CPC Central Committee held the 24th collective study on the research and application prospects of quantum science and technology. This is another key study of the Political Bureau of the CPC Central Committee on frontier science and technology after big data, artificial intelligence and blockchain. Quantum technology itself is one of the core contents of digital technology and the core force to promote the digital economy era
what is quantum? Quantum is an important concept in modern physics, which refers to the smallest and indivisible basic unit of a physical quantity. It is fundamentally different from the classical physics represented by Newton mechanics
for a while, quantum technology has become a hot word, and a large number of search and interpretation for the keywords of "Quantum Science" and "quantum communication" have appeared on the Internet. These three words should not be confused“ "Quantum Science" refers to the effect of quantum in science, which is a subject system of quantum information“ "Quantum communication" is the application of quantum in the field of communication, that is to encrypt the communication to ensure security. Although communication is a very important application of quantum technology, quantum communication cannot be equated with quantum technology itself
compared with some improved technologies in the scientific community, quantum technology has a subversive effect. What it subverts is the current mainstream electronic computing, that is, the traditional and mainstream computer or the computer based on von Neumann structure with electrons as the basic carrier. At the same time, the chip, the electronic component of the mainstream computer, is also based on electrons, According to the economic law of Moore's law, the process of making computer chips has developed from 14 nm, 7 nm to 5 nm
but the problem is that Moore's law is approaching the physical limit, so there is an urgent need for some disruptive technologies in the field of science and technology, which take quantum as the basic unit of calculation and innovate the computing architecture with electron as the basic unit
the "trend" in the "grasp the general trend" mentioned by the Political Bureau of the CPC Central Committee in this study is that the foundation of information technology in the whole world is changing, and it is entering a new dividing point of computing architecture and basic ability breakthrough, so it is necessary to rebuild a new system in advance, which involves basic theory, basic materials, basic technology and basic technology Basic technology and device equipment, and the formation of a wide range of applications of quantum technology, and ultimately change the entire digital technology. Once the country has mastered this technology, it will make a great breakthrough in computing power and form a revolutionary impact on social development. In this regard, the starting point at home and abroad is basically the same, and the whole world has entered the "no man's land" together. Because of this, quantum technology is also a strategic area for all countries
it can be seen that under the current situation, the development of quantum technology has great strategic significance
in the world, quantum technology is still developed by enterprises in the form of instry university research. The more typical enterprises in the world are IBM and Google. Google built the first quantum computer in 2019, which only takes 200 seconds to complete a calculation, while it takes about 10000 years to use traditional computers
in the research of quantum technology, China goes hand in hand with European and American countries, at least not in a backward position. It should be noted that the technology has made some breakthroughs in the world, but it is not in a mature stage of development, so China still has a great opportunity to lead the competition. In China, quantum technology is still dominated by enterprises. The world's first quantum science experimental satellite "Mozi" from China and China's first quantum secure communication backbone network are all the results of enterprise oriented and instry university research cooperation. Some of the projects are led by GuoDun quantum enterprises incubated by the Chinese Academy of Sciences. Tencent has set up a quantum computing laboratory, which focuses on applications in information processing, such as the help of quantum algorithms to machine learning; We are also actively exploring more classical calculation or simulation methods for some small systems and molecules, and applying them in pharmaceutical, material, chemical and other instries< In the final analysis, there are two essential meanings of quantum technology: one is to improve the security of information and communication; Second, improve the computing power. At present, quantum computing can be widely used in many instries.
quantum technology is an important force in digital technology system. Throughout the study focus put forward by the Political Bureau of the CPC Central Committee, whether it is quantum technology, or big data, artificial intelligence, blockchain, they are the core content of digital technology and the core force to promote the era of digital economy
digital technology is a science and technology that uses the data of the physical world to construct a digital world that forms a mapping relationship with the physical world, and uses computing power and algorithms to proce useful information and knowledge to guide and optimize the economic and social operation in the physical world
digital technology is an iterative upgrade of the new generation of information technology. With the continuous advancement of the digital process, the connotation of "new generation information technology" is greatly broadened, and new technologies such as cloud computing, big data, mobile Internet, Internet of things, artificial intelligence, blockchain emerge in endlessly. Quantum computing, brain computer interface and other technology fields have broken through the scope of traditional information technology fields, and will probably change the whole information computing system
from the practice of digital technology innovation of major countries and leading enterprises in the world, digital technology has graally become a new hot spot of innovation and competition among countries. On the one hand, the major digital technology giants focus on digital technology and digital technology, such as Google's AI, quantum computing and knowledge automation engine technology; Cloud computing and AI of Microsoft and Amazon; Digital twin breakthroughs of Dassault, PTC, Siemens, ESI, etc; Apple's closed digital technology ecosystem based on processor innovation
on the other hand, the innovation of digital technology giants is inseparable from data science and technology digitization. For example, Google waymo driverless needs to continuously integrate digital technology with automobile related disciplines, technologies and instries to realize the value realization from data to domain knowledge
from the perspective of economic development, digital technology has changed workers from people to "people + machines", and workers can show exponential growth; It turns the means of proction into "instrial and agricultural supplies + data", and the data changes from tangible to intangible, and there is no quantity limit; The means of labor has become "instrial and agricultural equipment + computing power driven digital technology equipment", showing exponential growth, the proctivity has been unprecedented liberation, and human society has rapidly entered the digital era. It can be said that digital technology points to digital economy in the short term and knowledge civilization in the long term
from the perspective of promoting innovation, digital technology drives network collaborative innovation mode. In the instrial age, the innovation process is a one-way linear process from basic research to applied research and then to "chain innovation" of instrial development. Digital science and technology needs to face the interaction and integration of the physical world and the digital world. On the one hand, it needs to solve the practical application, face the needs of users, and develop the scene type R & D and innovation of a new market. Starting from the needs of users, it forms a reverse traction for scientific research. On the other hand, it needs to seek breakthroughs in various basic disciplines and basic technology fields. Each innovation subject is one of the nodes in the huge network system, and will participate in the whole process of the development and application of new science, new technology and new procts, which greatly shortens the innovation instrialization cycle
therefore, with the change of proction factors and innovation mode, digital technology will eventually reshape the global economic competition pattern. In the early days of the development of digital economy, digitization triggered the service instry to enter into more complex traditional fields such as instry, energy and transportation. However, with the development of digital technology, it is now more to change the whole process from data to information to knowledge through data processing, simulation modeling and machine learning, and push it into the stage of knowledge automation, Make data into the system of value creation. This power determines that digital technology will reshape the global economic and instrial pattern, and it will inevitably be the strategic commanding point of competition between big countries and enterprises
