Computer science belongs to science and engineering.
There are two types of computer related majors: the first is computer applications, and the second is e-commerce professionals. Cultivate high-level specialized scientific and technical personnel with good scientific literacy and a systematic and good grasp of the basic theory, basic knowledge, basic skills and methods of computer science and technology, including computer hardware, software and application.
At present, the computer specialty in China is mainly divided into three categories: basic computer specialty, computer specialty crossing science and engineering, and computer specialty crossing arts and liberal arts. It mainly includes computer science and technology, software engineering, bank network engineering, information security, Internet of Things engineering, digital media technology, intelligent science and technology, spatial information and digital technology, electronic and computer engineering, etc.
A bare metal computer consists of a hardware system and a software system, without any software installed. It can be divided into five categories: supercomputer, industrial control computer, network computer, personal computer and embedded computer. More advanced computers include biological computer, photon computer, quantum computer, etc.
Computer inventor John von Neumann. Computer is one of the most advanced scientific and technological inventions in the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality.
Its application field has expanded from the initial military scientific research application to various fields of society. It has formed a huge computer industry, which has driven the global technological progress, thus triggering profound social changes. Computers have spread throughout general schools, enterprises and institutions, entered ordinary people's homes, and become an indispensable tool in the information society.
Peanut butter and chocolate. Rice and soy sauce. Milk and biscuits. When two good things are combined, they can create better things. This is the case with quantum information, the combination of quantum physics and computational theory. The National Institute of Standards and Technology (NIST) has contributed to most of its history and is helping shape its future.
Carl Williams, a physicist at NIST, said, "We were there from the beginning. Since the beginning of the 21st century, he has been guiding most of the work of Pailingbian in this field. Now we can see that quantum information has transferred from a pure scientific field to a technical field.
In the near future, the quantum version of the traditional computer can be used for complex simulation to generate new drugs and high-tech materials. In the long run, a more powerful quantum computer, if it can be built, can quickly break the current digital security that protects online banking and shopping. But don't be afraid: post quantum encryption can also protect data from quantum network attacks launched by opponents. Quantum random number generator can generate the most unpredictable numbers in real time for encryption and other purposes.
Many other quantum information applications may appear on the market in the next decade. They include advanced quantum sensors that can reveal underground oil and mineral deposits. Quantum information technology may lead to new portable navigation devices. Even if the GPS network is disturbed or destroyed, soldiers can use these devices to find their own way.
NIST has always been the core of this quantum information revolution because of its extensive scientific expertise and culture of fostering interaction between professionals in many fields.
It is worth noting that the partnership between NIST and public universities has created a special research institution that combines the great potential of curiosity driven research with the resources of the federal government.
Gretchen Campbell, joint director of JQI, said: "This is really for scientists to study quantum phenomena from different aspects, and learn to share ideas and speak each other's language, so as to promote the progress of this field faster." The quantum revolution is now spreading beyond universities and federal laboratories. The company is investing hundreds of millions of dollars in the race to build quantum computers, which is expected to disrupt the industry and significantly improve technology.
