In order to enable new applications like ultra-secure communication and a new generation of high-performance computing, quantum communication makes use of the special qualities of quantum entanglement.
The range of current quantum networks is constrained. A quantum satellite communicates with a ground station by using photons that are inextricably linked or “entangled” by the laws of quantum mechanics.
Pairs of entangled photons, twinned light particles whose properties remain interwoven regardless of how far apart they are, are produced by the satellite. Parallel quantum computing is made possible via quantum communication, which allows qubits to communicate across vast distances.
The Global Quantum Based Satellite Communication Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
On Wednesday, China launched a brand-new quantum satellite that may mark the beginning of the establishment of a highly secure global communications network.
According to Xinhua, it was one of six satellites that the Lijian fast response rocket launched at midday from the Jiuquan Satellite Launch Complex in the Gobi Desert. The Chinese Academy of Sciences’ quantum satellite would carry out experiments involving the dissemination of quantum keys in low-Earth orbit.
Whereas regular communication satellites primarily act as a relay, a quantum satellite’s primary function is to produce entangled particles that can be utilised as quantum keys. In the future, the quantum keys might be a crucial resource for international communication.
Entangled particles are used in a quantum key network to encrypt data. Due to the principles of quantum physics, any attempt to steal or decode the information will physically change the message and notify the recipient. China launched the world’s first quantum satellite, Mozi, into orbit before launching this second one.
After a month of testing, Jinan 1 would go into service, and it was described as “only the beginning step.” In the near future, more of these satellites will be deployed in order to allow quantum communication for more than 100 people worldwide. That is a crucial stage as well. As a result, China becomes the first nation in the world to successfully implement real-time, satellite-to-ground quantum key distribution using miniature satellites and ground stations.
