A satellite, nicknamed Micius or Mozi after the ancient Chinese philosopher and scientist, is operated by the C The US and China are in a quantum arms race that will transform warfare. Quantum communications could make stealing secret messages much harder, or impossible.
Tiangong-2 carries a total of 14 mission and experiment packages, including Space-Earth quantum key distribution and laser communications experiment to facilitate space-to-ground quantum communication. Chinese researchers have already built a satellite that can send quantum-encrypted messages between distant locations, as well as a terrestrial network that stretches between Beijing and Shanghai. Long ground networks require way stations similar to the repeaters that boost signals along an ordinary data cable. Any that are must have originated at the radar station. Quantum Experiments at Space Scale, is a Chinese research project in the field of quantum physics. A professor at the University of Waterloo in Canada, Baugh is working on a device that’s part of a bigger project to develop quantum radar. Quantum communication through satellite transmission is, in simple terms, the mixture of two distinct technological realms: quantum mechanics-based communication and satellite communication (SATCOM). A change in one photon immediately influences the state of the other, even if they are separated by vast distances.Quantum radar operates by taking one photon from every pair generated and firing it out in a microwave beam. That might mean the devices could be used in the future to spot submarines at much longer ranges.It’s still early days for militaries' use of quantum technologies. The distance is about 10 times further than the old, optic fiber-based quantum tech could do.
it is unhackable. Using this satellite, Chinese researchers at the Quantum Experiments at Space Scale (QUESS) project, were able to transmit secret messages from space to … While China lags on research into quantum computing, it’s quickly catching up.

It's another kind of "quantum supremacy" – a Chinese team of scientists have successfully established a satellite-based quantum network that can send passwords 1,120 kilometers away. Baugh’s radar research, for instance, is funded by the Canadian government, and the US is planning a joint research initiative with its closest military partners—Canada, the UK, Australia, and New Zealand—in areas like quantum navigation.All this has given the US has a head start in the quantum arms race. China's 2016 launch of the first experimental quantum communications satellite represented a "notable advance in cryptography research," according to a Pentagon report to Congress released on Tuesday.
The satellite passes 500km over China for just less than five minutes each day - or rather each night, as bright sunlight would easily swamp the quantum signal.

Research into quantum navigation and sensing technology is under way at various institutes across the country, according to the CNAS report.As well as being used for navigation, magnetometers can also detect and track the movement of large metallic objects, like submarines, by fluctuations they cause in local magnetic fields. This poses a risk because an enemy could falsify, or “spoof,” GPS signals—or jam them altogether.Lockheed Martin thinks American sailors could use a quantum compass based on microscopic synthetic diamonds with atomic flaws known as nitrogen-vacancy centers, or NV centers. But they also count on signals from the Global Positioning System (GPS), a network of satellites orbiting Earth. There’s no guarantee they will work well at scale, or in conflict situations where absolute reliability is essential. As well as unstealthing aircraft, they could bolster the security of battlefield communications and affect the ability of submarines to navigate the oceans undetected. “The developer of the satellite claimed it has ‘enormous prospects’ in defense, moving China closer to more secure communications,” the report said. Because they are very sensitive, the magnetometers are easily disrupted by background noise, so for now they are used for detection only at very short distances.
These qubits are typically photons that can travel easily across fiber-optic networks or through the atmosphere. quantum satellite Blogs, Comments and Archive News on Economictimes.com
