    Default 'Hack-proof' Quantum Communications Chinese Satellite

    One Giant (Quantum) Leap as China Launches 'Hack-Proof' Satellite

    Once upon a time in China, scientific discoveries and tech inventions were celebrated, and to this day are still revered for their historical significance and as symbols of ancient China's advanced innovation in these areas.

    What is referred to in Chinese culture as the "Four Great Inventions" that had a significant impact on the development of civilisation throughout the world are inventions such as the compass, gunpowder, paper-making and printing.

    Over the last decade there has been a steady revival in both science and tech innovation in China again, mainly as a result of the rise in economic developments, and now it is said to have put in place one of the world's largest army of scientists and engineers to reclaim the same glory days of history.

    ​Something that could certainly make (quantum) leaps in innovation has been announced this week as China launched the world's first quantum 'hack-proof' satellite. It is said to help it establish "hack-proof" communications between space and the ground, and one of the latest advances in it's ambitious wider space programme.

    The overall program is a priority as Xi Jinping, the president, has urged China to establish itself as a space power, and apart from its civilian ambitions, it has also tested anti-satellite missiles.

    ​The Quantum Experiments at Space Scale (QUESS) satellite, was launched from the Jiuquan Satellite Launch Centre in the remote northwestern province of Ga nsu in the early hours of Tuesday this week, as reported by China's state media.

    "In its two-year mission, QUESS is designed to establish 'hack-proof' quantum communications by transmitting uncrackable keys from space to the ground," it was reported.

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

    The satellite is said to enable secure communications between Beijing and Urumqi, according to media reports referring to the capital of China's violence-prone far western region of Xinjiang, where the government says it is battling an Islamist insurgency.

    It was eight years ago that quantum physicist Pan Jianwei and space engineer Wang Jianyu teamed up to build this world's first quantum satellite in the hope of finding the portal to a whole new universe.

    ​"The newly-launched satellite marks a transition in China's role — from a follower in classic information technology development to one of the leaders guiding future achievements," Pan Jianwei, the project's chief scientist, told national press in China.

    Talking to Chinese press, Wang Jianyu, fellow physicist on the project also added:

    "The QUESS missions are something never attempted by other nations. China has been trailing the footsteps of others for more than a century and QUESS is a tiny step, but it is a step for the entire human race," he said.

    Quantum communications is said to hold "enormous prospects" in many areas of tech development, including in the field of defence.

    China insists its space programme is for peaceful purposes, but the US Defense Department has highlighted its own increasing space capabilities, saying it was pursuing activities aimed to prevent adversaries from using space-based assets in any crisis.

    The quantum satellite for the first time may also prove that quantum communication on a worldwide scale can be possible as has been studied and debated by physicists worldwide.

    ​So we will watch this "space" for further leaps in Quantum Science such as the possibility of worldwide Quantum Internet networks also becoming an ever-closer reality one day.

    I have always believed that the Chinese will make first contact and I don't know why I think that.

    Pretty sure first contact has already been made, Assuming you mean the first country where it is out in the open, then, I think as you do. The more Chinese people I get to know (and there are lots in Chinese in Sydney!), the more I get validation that this hunch is accurate.

    Chinese scientists have announced that they have received the first batch of data from the recently-launched Micius satellite, which is designed for quantum physics research with the aim of potentially establishing “hack-proof” communication links.

    The Chinese Academy of Sciences announced that the Remote Sensing Satellite Ground Station (RSGS) in Miyun, on the outskirts of Beijing, has established a link with the newly-launched satellite, Xinhua reported.

    The first batch which was transmitted on Wednesday included 202 megabytes of data and was received in “good quality,” according to the publication. The data was transferred to China’s National Space Science Center for further analysis.

    The world’s first quantum communications satellite took off from the Jiuquan Satellite Launch Center in Gobi Desert on Tuesday for at least a two-year mission. The main task of the Chinese satellite is to potentially secure communications in an age of cyberattacks and global electronic surveillance.

    The 600+kg Quantum Experiments at Space Scale (QUESS) is nicknamed 'Micius' in honor of the fifth century BC Chinese philosopher and scientist.

    The satellite is positioned in a sun-synchronous orbit, some 600km (373 miles) above the Earth, and, as well as the RSGS in Miyun, it will in the future be linked to a station in Kashgar, northwestern China, and in Sanya, southern China.

    The world's first quantum satellite was launched in China Tuesday. Nicknamed Micius, the satellite will be able to send ciphers that are virtually impossible to wiretap. Let's try to understand its working theory.
