Zhou Fei, Assistant Director of the Jinan Institute of Quantum Technology, says of the network, “We plan to use the network for national defense, finance and other fields, and hope to spread it out as a pilot that if successful, can be used across China and the whole world.” He suggests the system will have a global impact.
China is already becoming a world leader in quantum communications technology; a satellite that delivers quantum communications will be a cornerstone for translating cutting-edge research into a strategic asset for Chinese power worldwide.The program marks a significant shift in Chinese space programs, which have largely focused on human and robotic space exploration rather than space science. Pan noted that the unbreakable security of quantum cryptography would be vital to any Chinese regional warfighting capabilities.QUESS fits into a broader series of experimental quantum encryption programs which may be intended to address concerns over China's information security, particularly in the post Snowden era.Quantum encryption thus takes advantage of this feature, using it to detect would-be eavesdroppers, whose presence causes quantum states to collapse and reveal their spying to legitimate parties.Additionally, the complexity of quantum mechanics makes it virtually impossible to reverse engineer the quantum key generated through quantum entanglement.In the age of relentless cyberattacks and global electronic surveillance, nations and citizens are looking for any means to secure their communications.
China is poised to launch a project that may provide the path to an uncrackable communications system, by turning messages quantum and taking them into space.
The government has requested ¥300 million from the 2018 budget to kickstart the project by developing a satellite hosted laser capable of the communication.
The newly developed laser is set to be tested in 2022 using either satellites or aircraft capable of high-altitude flights. Japanese newspaper Yomiuri Shimbun reported that the government is looking to team up with private companies to realize its ambitious communications project.
These complex systems apply the properties of quantum mechanics to a communication system.
The proposed Japanese system would work when an orbiting satellite receives instructions to deliver a set of keys to both communication sender and receiver.
Quantum secured communications, like other forms of encryption, are vulnerable to denial of service, physically tampering of the quantum communications device, human failures in operational security and impersonation of sender).
