The Hacker News - Cybersecurity News and Analysis: Quantum Communication

In what appears to be the world's first quantum satellite transmission, China has successfully sent an "unbreakable" code over a long distance from an orbiting satellite to the Earth, achieving a milestone in the next generation encryption based on "quantum cryptography." In August last year, China launched the world's first quantum communication satellite into the Earth's orbit aboard a Long March-2D rocket to test the fundamental laws of quantum mechanics at space. Dubbed Quantum Science Satellite , nicknamed Micius or Mozi (Chinese: 墨子), the satellite was designed to establish a 'Hack-Proof' communications system in this age of global surveillance by transmitting unbreakable encryption keys from space to the ground. Now, it has been reported that using this satellite, the Chinese scientists at the Quantum Experiments at Space Scale (QUESS) project were able to send secret "quantum key distribution" (QKD) data by beaming photons

Quantum Computers – Boon or Bane? Quantum computers can perform operations much more quickly and efficiently even with the use of less energy than conventional computers, but that's bad news for encryption — a process which scrambles data according to a massively complex mathematical code. In theory, quantum computers can break almost all the existing encryption algorithms used on the Internet today due to their immense computing power. Quantum computers are not just in theories; they're becoming a reality. With countries like China that holds the top two position in the world's most powerful supercomputers (Sunway TaihuLight and Tianhe-2), followed by the United States' Titan, the day is not far when Quantum computers will work on an industrial scale. Although it's hard to move quantum computing to an industrial scale, it has become a matter of concern for the United States' National Institute of Standards and Technology (NIST) over the fact that

China has taken one more step forward towards achieving success in Quantum communication technology. China has launched the world's first quantum communications satellite into orbit aboard a Long March-2D rocket earlier today in order to test the fundamental laws of quantum mechanics at space. 'Hack-Proof' Communications System The satellite, dubbed Quantum Science Satellite, is designed to develop a ' Hack-Proof ' communications system in this age of global electronic surveillance and cyber attacks by transmitting uncrackable encryption keys from space to the ground. The 600-plus-kilogram Quantum Science Satellite , better known as Quantum Experiments at Space Scale (QUESS) satellite, took off from the Jiuquan Satellite Launch Center in Gobi Desert at 1:40 AM local time on a 2-year mission on Tuesday. The QUESS satellite will help China perform unprecedented levels of experiments in quantum communication by sending entangled photons from the satellite
