The scientist in charge of China’s quantum satellite effort is Jian-Wei Pan, who is the senior author on the Nature paper. Scientists have now reported using this technology to reach a major milestone: Long-range secure communication you could trust even without trusting the satellite it runs through. In the new paper, Dr. Pan’s team reported that it had increased the efficiency of the communications link by upgrading the telescopes and optics as well as the fine tracking of targets among the system’s far-flung parts. 9 Oregon, Gold jewellery retail industry expects demand recovery in H2FY21: ICRA, GIJN launches comprehensive guide on ‘Investigating Health and Medicine’, THESE are the 5 most fearless zodiac signs who stand tall in the face of fear, BMW eDrive Zones help get the best from plug-in cars, How does a Ring doorbell work?

But the satellite is a strategic resource that other countries are likely to want to replicate, just as Europe, Russia and China now have their own versions of the US-controlled GPS. Dr. Earl estimated that matching China’s quantum accomplishments in orbit will take the unclassified parts of the United States program another three years “and maybe longer, which is pretty concerning. The program was initiated in 2018. Connect with friends faster than ever with the new Facebook app. But both ground stations had to talk to and trust Micius as part of their communication systems and use it as a relay before establishing a link with each other. Until now, this had never been done via satellite or at such great distances. Named after the ancient Chinese philosopher also known as Mozi, Micius is the world’s first quantum communications satellite and has, for several years, been at the forefront of quantum encryption.

If you manipulate one of the photons, the other will be similarly affected at the very same moment. The launch of Micius and the records set by the scientists and engineers building quantum communication systems with its help have been compared to the effect Sputnik had on the space race in the 20th century. But the satellite is a strategic resource that other countries are likely to want to replicate, just as Europe, Russia and China now have their own versions of the US-controlled GPS. Pan Jian-Wei credited Edward Snowden’s 2013 disclosures of internet surveillance by western governments with prompting China to boost quantum cryptography research in order to create more secure means of communication. This also involved designing the machinery for distributing the keys and a mechanism for preventing malicious attacks, such as blinding the telescopes with other light signals. Duncan Earl, a former scientist at Oak Ridge National Laboratory and president and chief technology officer of Qubitekk, a company in Vista, Calif., that is exploring quantum encryption, said that the Chinese advance appeared to be significant. Traditional communications satellites used radio waves to send signals. Micius has previously produced entangled photons and delivered them to two ground stations (observatories) 1,200km apart via special telescopes. We believe information is a powerful driver for the new tomorrow. Named after the ancient Chinese philosopher also known as Mozi, Micius is the world’s first quantum communications satellite and has, for several years, been at the forefront of quantum encryption. However, the news of a successful long-distance quantum communications link is a sign that we are already living in a new era of communication security. In the middle of the night, invisible to anyone but special telescopes in two Chinese observatories, satellite Micius sends particles of light to Earth to establish the world’s most secure communication link.

Secure long-distance links such as this one will be the foundation of the quantum internet, the future global network with added security powered by laws of quantum mechanics, unmatched by classical cryptographic methods. It posits that a pair of widely separated subatomic particles can still seem instantaneously linked: Measuring a property of one will simultaneously affect the measured results on its companion, even if the two are millions of light-years apart. Quantum encryption relies on entangled particles of light. it intends to use a laser system on the International Space Station.

In contrast, the quantum communication satellite uses pairs of entangled photons, or light particles, whose properties remain entwined even as one photon is transmitted over a long distance. This article has been amended to correct the time at which distribution machinery and attack prevention were developed, Harun Šiljak, Postdoctoral Research Fellow in Complex Systems Science for Telecommunications, Trinity College Dublin. In the journal Nature on Monday, the team of 24 scientists describe successfully testing the transmission of a “secret key” for encrypting and decrypting messages between a satellite and two ground stations located roughly 700 miles apart. It fired concentrated beams of laser light to relay the quantum signals between two telescopes built at ground stations in Delingha and Nanshan, in China, 700 miles apart. But this time the satellite sent simultaneous streams of entangled photons to the ground stations to establish a direct link between the two of them. The satellite provided entangled photons as a convenient resource for the quantum cryptography and the two ground stations then used them according to their agreed protocol.

A 2012 profile of Dr. Pan in Nature reported that he was in his early 30s when, in 2001, he set up China’s first laboratory for manipulating the quantum properties of photons.
