Popular Post seeder Posted July 12, 2017 Popular Post #1 Share Posted July 12, 2017 Quote First Object Teleported from Earth to Orbit Researchers in China have teleported a photon from the ground to a satellite orbiting more than 500 kilometers above. Last year, a Long March 2D rocket took off from the Jiuquan Satellite Launch Centre in the Gobi Desert carrying a satellite called Micius, named after an ancient Chinese philosopher who died in 391 B.C. The rocket placed Micius in a Sun-synchronous orbit so that it passes over the same point on Earth at the same time each day. Micius is a highly sensitive photon receiver that can detect the quantum states of single photons fired from the ground. That’s important because it should allow scientists to test the technological building blocks for various quantum feats such as entanglement, cryptography, and teleportation. https://www.technologyreview.com/s/608252/first-object-teleported-from-earth-to-orbit/ 12 Link to comment Share on other sites More sharing options...
seeder Posted July 12, 2017 Author #2 Share Posted July 12, 2017 This link has a soundfile explanation Quote First object teleported to Earth's orbit Chinese researchers have teleported a photon from the Gobi desert to a satellite orbiting five hundred kilometres above the earth. This is achieved through quantum entanglement, a process where two particles react as one with no physical connection between them. Hooke Professor of Experimental Physics at Oxford University Ian Walmsley tells the World At One how quantum entanglement works and how teleportation could be utilised. http://www.bbc.co.uk/news/av/science-environment-40573621/first-object-teleported-to-earth-s-orbit 3 Link to comment Share on other sites More sharing options...

Grandpa Greenman Posted July 12, 2017 #4 Share Posted July 12, 2017 Awesome, It is a big step. It will bring on a new era for communication and space robotics. They will be able to drive those little rovers in real time. 5 Link to comment Share on other sites More sharing options...

fred_mc Posted July 12, 2017 #7 Share Posted July 12, 2017 (edited) In the future, I can imagine that we will have quantum entangled particle pairs, such as electrons, where one of the particles is on Earth and the other on a Mars station. Then people on Earth and Mars will be able to communicate with each other in real-time since changing the property of one particle in the pair will immediately change the same property of the other. We will not have to care about the speed of light as we would if we communicated using radio waves. Edited July 12, 2017 by fred_mc 3 Link to comment Share on other sites More sharing options...
paperdyer Posted July 12, 2017 #8 Share Posted July 12, 2017 (edited) So much for firewalls on our computers and the evaporation of what little privacy we have left. As far as the secure quantum internet goes, nothing is hack-proof. Edited July 12, 2017 by paperdyer 1 Link to comment Share on other sites More sharing options...

Unfortunately all experiments have shown that it is impossible to use quantum entanglement for faster than light communication. 2 Link to comment Share on other sites More sharing options...

SHaYap Posted July 13, 2017 #14 Share Posted July 13, 2017 A little in depth background on 'Mozi' / Micius : Quote Source: "The ethical and political works of Motse", W. P. Mei, Probsthain, 1929 - Romanisation changed from Wade-Giles to Pinyin N.B. W.P. Mei's translation omits the Canons, Daqu, Xiaoqu, and the military chapters. English translation of the Canons is based on that in A.C. Graham's "Later Mohist Logic, Ethics, and Science", Chinese University Press, 1978 Chinese Text Project LINK ~ Quote Born in what is now Tengzhou, Shandong Province, he founded the school of Mohism that argued strongly against Confucianism and Taoism. His philosophy emphasized self-restraint, self-reflection and authenticity rather than obedience to ritual. During the Warring States period, Mohism was actively developed and practiced in many states but fell out of favour when the legalist Qin dynasty came to power. During that period, many Mohist classics are by many believed to have been ruined when the emperor Qin Shi Huang supposedly carried out the burning of books and burying of scholars. The importance of Mohism further declined when Confucianism became the dominant school of thought during the Han Dynasty, until mostly disappearing by the middle of the Western Han dynasty.[2] Mozi is known by children throughout Chinese culture by way of the Thousand Character Classic, which records that he was saddened when he saw dyeing of pure white silk, which embodied his conception of austerity (simplicity, chastity). wiki link ~ 1 Link to comment Share on other sites More sharing options...

The photons must have been entangled in a lab on Earth and then one of them sent on a rocket taking a satellite into orbit. The story got it very wrong when it said "... teleported a photon from the ground to a satellite...". The photon was not teleported. It in the satellite when it was launched. 4 Link to comment Share on other sites More sharing options...
EBE Hybrid Posted July 13, 2017 #16 Share Posted July 13, 2017 (edited) I imagine that if you were to 128 pairs of individually entangled particles, send half out into space whilst the other half are at a base station, you'd be able to have 128 bit instant telemetry and communications Edited July 13, 2017 by EBE Hybrid 1 Link to comment Share on other sites More sharing options...

Guest brizink Posted July 13, 2017 #18 Share Posted July 13, 2017 Well it sounds like that's exactly what's been done. And his proposal for 128bit communication is perfectly doable. Although technically you'd either need a quantum processor or a chipset that Includes double the entangled particles, one half for sending and the other half for receiving. And a mirror-chip on the ground. In Concept anyway. It could actually work. Link to comment Share on other sites More sharing options...

Quantum processors work by using their superpositions as replacements for the standard on/off states of traditional computers. You cannot use "entanglement" as a way of transmitting information, for the simple reason you cannot control what it is you're doing to the entanglement. Forcing a certain state on the particle breaks the entanglement. 3 Link to comment Share on other sites More sharing options...

Forcing a certain state on the particle breaks the entanglement. Sadly, exactly this. Quora has many answers that expand on this. Chad Orzel also posted a fairly decent laymen's explanation on Forbes. I don't know why but every time I read about this, this (unrelated?) quote pops into my head: Hap: "Time's funny stuff Pete. Even funnier than Einstein figured out." Pete: "Yeah? How'd he take it?" -Always (1989) Edited July 14, 2017 by Calibeliever 1 Link to comment Share on other sites More sharing options...

Guest brizink Posted July 15, 2017 #24 Share Posted July 15, 2017 Budging would be something like using entangled particles to react to circumstance along spacetime without damaging the entanglement, but still be able to detect the change in the point b particle, this allowing the flow of data but without killing your medium per bit of data. It's just a theory, but then again so is gravity. Can be done. Magnetics has shown promise in a similar concept. Entanglement could be far more efficient.
