The first 'impregnable' Internet network in the world

China has begun to establish the world's first "hackable" internet communication network with quantum technology.

Despite being a country famous for internet restriction policies, China seems to be at the forefront of developing a new generation internet communication network.

Jinan City has recently been selected as the center for developing a quantum information network. This is said to be the world's first "inviolable" information transmission network.

Quantum cryptography is arguably one of the best ways to secure internet communications - (Photo: EP).

Unlike encryption methods that hide the key with complex formulas, quantum information and quantum cryptography using 'quantum entanglement' or ' quantum entanglement' to create protection class.

Specifically, the key is embedded in photons (photonic / photonic particles) and sent before the message is encrypted - a method called quantum key distribution QKD (Quantum key distribution).

In this way, the information transmission network will not be hacked, because any attempt to intercept the keys will be immediately detected by the sender and the recipient and they will no longer use that key.

Even more impressive is that China has the technology to expand quantum communication up to 400km. This was previously demonstrated in a study in Hefei, Anhui Province.

It seems that China is leaving the West behind in the race for quantum technology.

While the West has not focused much on this technology, China has the ambition to use it for its entire communications system in the future - (Photo: PW).

Speaking to the BBC, Professor Myungshik Kim, Royal University of London, said: "For a long time, people do not think that it is necessary to develop new technologies because of the complexity of today's coding system. high'.

Recent security vulnerabilities and cyber attacks have proved that this way of thinking is completely wrong and that is why China pursues quantum communication.

Zhou Fei, a technician of the China Quantum Technology Assistant Institute, revealed to the Financial Times: "We plan to use the network in Jinan to protect national security, finance, as well as the If you succeed, it can be used across China and around the world ".

Quantum entanglement is a phenomenon in which two photons (photons) are created at the same time in connection with each other. Indeed, if two photons are created at the same time and placed in two different positions, they will not exist separately, but on the contrary, there will always be close ties - the state of This photon determines the state of the other photon.

If we force this photon to follow a certain quantum state, the other photon immediately has a corresponding quantum state as well. In other words, if you know the state of this photon, you will immediately know the state of the other photon.
