Quantum information science is quantum mechanics and information product of the combination of science， including quantum cryptography， quantum communication， quantum computation and quantum In recent years， quantum information science in theory and experiment have made an important breakthrough， caused by governments， industry and IT industry Quantum mechanics in the peculiar physical phenomena in the field of information has a unique feature， in improving the computing speed， the protection of information security， increasing information capacity and improve the detection accuracy can be a breakthrough in the current information system of the classical The use of the basic principles of quantum mechanics and characteristics of a classic can solve some cases can not solve
仅作参考The quantum of quantum mechanics and informatics is a combination of information science， including quantum cryptography， quantum communication， quantum computing and quantum measurement In recent years， the quantum informatics in theory and experiment have important breakthrough， governments， and information technology industry Quantum mechanics in the strange phenomena in the field of information in a unique function， improve the calculation speed， information security， information capacity and improve the precision of the existing aspects can break through the limits of classical information Use the basic principle of quantum mechanics and characteristic can well solve the classical cases can solve some
Inertia is a very important concept in Understanding of inertia， the more recognition of objects with properties of keeping original motion state， the inertia (object will remain at rest or of uniform motion in a straight line)， the nature of reason is not in the interior of the object， also has nothing to do with But due to the uniformity of the object of time and space Along with the development of modern physics， general relativity and proposed that inertia is around by its expression objects associated with space-time quality distribution determines the nature of the An important progress for inertial understanding of relationships with energy and With inertial energy point of view to broaden the understanding of inertia， also broaden the understanding of Based on inertial essence as the research perspective， this paper expounds on inertia of the concept of development and change， human understanding of nature of various inertial phenomenon to broaden the understanding of inertia， focusing on the based on the Newton classic time-space conditions to explore the establishment of the law of inertia and the inertia in the high school physics teaching concept， the law of inertia， grasps the inertia and life closely related， introduces the application of inertia on the science and
