What is a quantum computer? Why can it change the world?

Do you think your payment procedure is absolutely safe? The appearance of the first quantum computer in the world poses a serious challenge to the security of traditional computers in the process of confidentiality. What is a quantum computer? How much do you know about this? When it comes to quantum, you may first think of various theories in quantum mechanics, such as Schrodinger's cat and quantum entanglement. It is precisely because of these theories that quantum computers can subvert traditional computers. Now, starting with bits, we will unveil the mystery of quantum computer step by step.

The first kind of quantum computer is a physical device that performs high-speed mathematical and logical operations, stores and processes quantum information according to the laws of quantum mechanics. If a device processes and calculates quantum information and runs quantum algorithms, it is a quantum computer. Quantum machine has the characteristics of fast operation speed, strong information processing ability and wide application. Compared with ordinary computers, the greater the amount of information processing, the greater the advantages of computational quantum computers, which can ensure the accuracy of calculation.

Quantum mechanics is a physical device for high-speed logical operation, storage and processing of quantum information according to the laws of quantum mechanics. Its basic laws include uncertainty principle, correspondence principle, Bohr theory and so on. It has a wide range of applications, such as electronic products mainly made of semiconductor materials, laser recording of optical disks, nuclear magnetic resonance and so on.

Theoretically, quantum mechanics has the ability to simulate any natural system and is the key to the development of artificial intelligence. Because quantum computer has powerful parallel computing ability, it can quickly complete calculations that classical computers can't. This advantage has great application in encryption, decoding and other fields.

(1) Weather forecast: If we use a quantum computer to analyze all the data at the same time and get the results, we can accurately know the direction of weather changes, thus avoiding huge economic losses.

(2) Drug research and development: Quantum computers also have great advantages in developing new drugs. It can draw the molecular composition diagram of 10 megabyte, and choose the most possible method from it, thus speeding up the invention of new drugs and making pharmacological analysis more personalized.

(3) Traffic scheduling: Quantum computer can predict traffic conditions according to the existing traffic conditions, complete in-depth analysis and optimize traffic scheduling.

(4) Secure communication: Not only in the similarity of our lives, but also because of the principle of non-cloning, the encryption of encrypted communication by quantum computer cannot be translated and eavesdropped without being discovered by intruders, which depends on the characteristics of quantum computer itself.

The theoretical running speed of quantum computer far exceeds that of any traditional supercomputer. This kind of computer may make it possible for people to simulate the state of matter at the atomic level, thus reshaping new material technology; They can also crack any existing encryption algorithm and redefine network security through unlimited examples; They can even improve the level of artificial intelligence by effectively processing massive data. The powerful ability of its quantum computer may be applied to more fields in the future. In the past few decades, the field of quantum computing has developed extremely rapidly. With the blessing of quantum computing, what can human science develop into? Let the future tell us.
