Chinese quantum satellite sends ‘unbreakable’ code which will self-destruct if hacked or tampered
Always trust the Chinese to do the unthinkable. They have come a long way from reverse-engineering products made in United States, Japan, and South Korea to build their own hack proof quantum satellite. Even in light of people making jokes about Chinese products being third class, their scientists are toiling hard to make new breakthroughs in teleportation tech which we had reported earlier. Now the Chinese scientists have made a new record by using their quantum satellite to send an unbreakable hack-proof code which will self-destruct if it is accessed by an unauthorized person or is tampered with.
Most people associate self-destruct tech with Snapchat so it would be right to call that Chinese scientists have managed to send “unbreakable” Snapchat code from a satellite to the Earth which will self-destruct in case if it is accessed by an unauthorized person or tampered with. China was the first country to teleport a ‘Photon’ 500 km into space like we used to see in the Star Trek movies and in the Star Trek TV show. Now Chinese have created another record by marking the first time space-to-ground quantum key distribution technology.
The teleportation and now the unbreakable code were sent using world’s first quantum satellite that China launched last August, to help establish “hack proof” communications, a development the Pentagon has called a “notable advance”.
The satellite sent totally hack-proof quantum keys to ground stations in China between 645 km (400 miles) and 1,200 km (745 miles) away at a transmission rate up to 20 orders of magnitude more efficient than an optical fibre, Xinhua cited Pan Jianwei, lead scientist on the experiment from the state-run Chinese Academy of Sciences, as saying. “That, for instance, can meet the demand of making an absolute safe phone call or transmitting a large amount of bank data,” Pan said.

What makes Chinese scientists attempt to send the unbreakable code from space to Earth is its self-destruct feature. Any attempt to eavesdrop on the quantum channel would introduce detectable disturbances to the system and make it destroy itself. “Once intercepted or measured, the quantum state of the key will change, and the information being intercepted will self-destruct,” Xinhua said.
The above news has to be taken with a pinch of salt as no other scientists from the world fraternity have confirmed it. China still lags behind the United States, India, and Russia in space technology though China is attempting to close in on the difference.
