Quantum computing could dwarf the processing

"
China successfully launched the world's first quantum satellite from the Jiuquan Satellite Launch Center in northwestern Gobi Desert at 1:40 a.m. on Tuesday.


In a cloud of thick smoke Kenny Clark Jersey , the satellite, Quantum Experiments at Space Scale (QUESS), roared into the dark sky on top of a Long March-2D rocket.


The 600-plus-kilogram satellite will circle the Earth once every 90 minutes after it enters a sun-synchronous orbit at an altitude of 500 kilometers.


It is nicknamed ""Micius,"" after a fifth century B.C. Chinese philosopher and scientist who has been credited as the first one in human history conducting optical experiments.


In its two-year mission, QUESS is designed to establish ""hack-proof"" quantum communications by transmitting uncrackable keys from space to the ground, and provide insights into the strangest phenomenon in quantum physics -- quantum entanglement.


Quantum communication boasts ultra-high security as a quantum photon can neither be separated nor duplicated. It is hence impossible to wiretap Vince Biegel Jersey , intercept or crack the information transmitted through it.

With the help of the new satellite, scientists will be able to test quantum key distribution between the satellite and ground stations, and conduct secure quantum communications between Beijing and Xinjiang's Urumqi.


QUESS Josh Jones Jersey , as planned, will also beam entangled photons to two earth stations, 1,200 kilometers apart, in a move to test quantum entanglement over a greater distance, as well as test quantum teleportation between a ground station in Ali Kevin King Jersey , Tibet, and itself.


""The newly-launched satellite marks a transition in China's role -- from a follower in classic information technology (IT) development to one of the leaders guiding future IT achievements,"" said Pan Jianwei, chief scientist of QUESS project with the Chinese Academy of Sciences (CAS).


The scientists now are expecting quantum communications to fundamentally change human development in the next two or three decades, as there are enormous prospects for applying the new generation of communication in fields like defense, military and finance.


SPOOKY & ENTANGLED


Quantum physics is the study of the basic building blocks of the world at a scale smaller than atoms. These tiny particles behave in a way that could overturn assumptions of how the world works.


One of the strange properties of quantum physics is that a tiny particle acts as if it's simultaneously in two locations -- a phenomenon known as ""superposition."" The noted interpretation is the thought experiment of Schrodinger's cat -- a scenario that presents a cat that may be simultaneously both alive and dead.


If that doesn't sound strange enough Randall Cobb Jersey , quantum physics has another phenomenon which is so confounded that Albert Einstein described as ""spooky action at a distance"" in 1948.


Scientists found that when two entangled particles are separated, one particle can somehow affect the action of the far-off twin at a speed faster than light.


Scientists liken it to two pieces of paper that are distant from each other: if you write on one, the other immediately shows your writing.


In the quantum entanglement theory, this bizarre connection can happen even when the two particles are separated by the galaxy.


By harnessing quantum entanglement, the quantum key technology is used in quantum communications, ruling out the possibility of wiretapping and perfectly securing the communication.


A quantum key is formed by a string of random numbers generated between two communicating users to encode information. Once intercepted or measured Jordy Nelson Jersey , the quantum state of the key will change, and the information being intercepted will self-destruct.


According to Pan, scientists also plan to test quantum key distribution between QUESS and ground stations in Austria. Italy, Germany and Canada, as they have expressed willingness to cooperate with China in future development of quantum satellite constellations, said Pan.


LIFE CHANGING


With the development of quantum technology Mike Daniels Jersey , quantum mechanics will change our lives in many ways. In addition to quantum communications, there are quantum computers that have also drawn attentions from scientists and governments worldwide.


Quantum computing could dwarf the processing power of today's supercomputers.


In normal silicon computer chips, data is rendered in one of two states: 0 or 1. However, in quantum computers, data could exist in both states simultaneously, holding exponentially more information.


One analogy to explain the concept of quantum computing is that it is like being able to read all the books in a library at the same time Clay Matthews Jersey , whereas conventional computing is like having to read them one after anothe Spinal surgeries are painful.
