Chinese Navy nuclear-powered submarines

"Time" magazine Sept. 9 article, the original title: China (quantum level) of the Great Leap Forward as a pair of drums with the breast glare of the male turkey , the United States in the army to return to each other retaliation for the status of . China may be trying to the United States send a simple signal : This is our backyard.

Seen the U.S. military in the first Gulf War 's performance , the Chinese recognize the need to improve their behind troops . Over the past 20 years, China has been increasing military expenditure. While China says with the United States relations is " stable " , but given China in the region 's ambitions , the two countries tensions between will continue.

East-West Center senior fellow Denny Roy , said , China " is trying to establish spheres of influence " , with the army more powerful , they are now able to " pass before can not afford the signals . "

It also benefited from recent technological breakthroughs. When the Chinese to show off new equipment , a potentially and more important military advances largely been ignored : in May , Chinese scientists announced that 16 kilometers of " long-distance quantum teleportation . "

China is now at military communications the forefront of , is changing the password field, to focus on the increasingly fierce military communications competition on . New technologies may greatly promote China's command and control capabilities.

Why is this communications technology than the e-mail and radio communications superior it? Because , in theory, this approach "can not be cracked or intercepted . "

16 kilometers from the communications test , the Chinese from its satellite network to ground send confidential information. quickly China's satellite will be able to with the submarine communicate , without the submarine surfaced , does not need the submarine to take to break radio silence exposure to the location the risk of . It sounds like science fiction , but quantum cryptography have been in China a number of banks more small-scale to use highly sensitive information on .

no person Chinese troops will soon be more than the U.S. , but alone with a duel of the Navy exercises can not determine the strength of the order of . It also depends on the Chinese the latest technology to military on how fast , and improve accuracy , coordination and secretive , while the PLA maintaining the strength of circumstances, such as cyberspace warfare. In this sense, China has made the quantum class leap in .

The reason that the communication technology breakthrough , because the quantum transmission technology marks the of China in military communications the field of standing the world forefront of , greatly enhance the PLA's command and control capabilities to the future China's military development with To revolutionary change. of quantum states Teleportation is a new means of communication, it transmission is no longer a classical information but the quantum states carried by quantum information , of a quantum the quantum state change in information will immediately by another the quantum receive , the future quantum communication network The core elements. The result is like with two apart 10 miles papers , one in which a piece of paper to write the time , another paper will immediately show the written information.

Quantum entanglement technologies, need to transfer the quantum state as science fiction depicted in , " Macross through the " in one place mysterious disappearance , does not require any carrier to carry, and in another moment of mystery appears. quantum communication technology The reason why than the average e-mail or radio superior to superior , because in this way in theory can not be destroyed or blocked. If the laser beam in the Quantum is third-party observed , the particle itself will change , and this is physics, the so-called " Heisenberg Uncertainty Theory ", a state-dependent the particle changes in is measured . If blocked, the sender and the recipient can immediately noticed someone snooping.

in quantum transmission Technological breakthroughs , which means China now has the top military communications capabilities, give an example, the short-wave in the water transmission attenuation very quickly and spread distance very short , so the submarine in order to obtain efficient communications capabilities Take the initiative to with the shore or in the air get in touch , only through the release buoy antenna or buoyant antenna, that is the antenna cast to the surface , so that submarines underwater can launch signals. In fact, this remains a submarine self- exposure, because the submarines at long range with short-wave communications , the signal itself is not confidential and may be by the enemy intercepted to decipher , and measured the submarine the position of , and the above the surface of the buoy antenna has Be enemy radar to detect possible , which greatly increased the submarine exposure to the probability of , dramatically reducing the submarine to covert the good ability to survive.

The long wave and very long-wave in the water attenuation is relatively small , and from the air penetrate into the water long-distance transmission , so that underwater submarines to receive to the shore sent radio waves . Especially at wavelengths greater than 100,000 m very long waves , almost at the global scale of submarine communication , and the penetration the water layer depth of up to 200 meters, even at maximum distance can reach underwater 80 meters about . So , now the submarine underwater communication or by Lai Changbo or very long-wave communications, but the long-wave and very long-wave communication equipment is very large , often covering an area of several square kilometers, can not be in the submarine placed , only in the land set , and More can not stand the long-wave communications efficiency is very low, often sending a group of dozens of characters the information needs of tens of minutes , which emergency war is inconceivable .

From the beginning, the Chinese experts to consider of this technology the military applications , the reason why in the choice of the quantum transmission technology the manner of selection of the blue , not the United States used in infrared light, having regard to the the submarine fleet development needs of ( Prior to China's navy the development direction of has been focused on the submarine ), because blue light at underwater can be transmitted greater distances .

Thus can be inferred that in the future near , the Chinese military satellites and submarines to the new real-time quantum communication , and no longer need to the submarine surfaced , or launch the radio to expose themselves the location of . Might imagine , this technology, so that the PLA's submarines for their command center is completely transparent to enemy each other for increases greatly detection the difficulty , therefore, China's second nuclear counter-attack could not be prevented and Blocked , which means that to the United States the strategic threat is fatal !

Quantum transmission technology not only underwater submarine communications has revolutionized significance to the aerospace , too, was due to quantum transmission technology very high secrecy (theoretically unbreakable ), will accelerate to change China's future the Air Force the development of the form of , perhaps the PLA The fourth generation machine is just a transitional model , the real by the development of the Five Dynasties machine , that no fighters, no bombers, they are the the future Chinese air force development of main force of , after the army fans some of "secret sword "This UAV impressive bar, the night view, it is the next Five machine a silhouette of !

Perhaps one or two of advanced weapons or technology can not decide a war the outcome of , but often these super- weapons and technology will definitely affect the course of the war , to the opponent the threat is also a fact exist. Is this technology can the PLA bring what military transformation , we will wait and see.
