China's new Dawn: Pan Jianwei reveals high-orbit quantum satellite for global network
China is developing the world's first high-orbit quantum communication satellite to enable more efficient, globally accessible quantum networks and lay the groundwork for redefining the international standard of the second, according to Pan Jianwei , the country's 'father of quantum'. Set to launch around 2027, the satellite will operate in geostationary orbit more than 35,000km (21,700 miles) above the Earth, Pan revealed during a pre-recorded keynote speech at a conference in Germany this month to mark the centenary of quantum mechanics. The satellite will carry an optical atomic clock and serve as a new platform for quantum metrology research, including efforts to improve the short-term stability of atomic clocks through global entanglement distribution, and potentially pave the way for a redefinition of the International System of Units (SI) base unit of time – the second. 11:05 Space race elevates Asia in new world order Space race elevates Asia in new world order The satellite – named Dawn – follows Micius , the world's first quantum satellite that was launched into low Earth orbit in 2016 by Pan's team at the University of Science and Technology of China. Pan revealed the satellite's name during a live Q&A session with more than 300 quantum physicists, including four Nobel laureates, who gathered on the island of Helgoland for the week-long meeting. Dawn was designed to extend entanglement distribution distances to over 10,000km, he said. 'A high-orbit satellite is incredibly powerful. It can simultaneously see two locations on Earth that are 10,000km apart,' he told state broadcaster CCTV in May. 'That makes it possible for us to establish key distributions between Beijing and South Africa.' Entanglement distribution from high orbit could also take place around the clock, thanks to the satellite's stationary position over Earth. 'That provides continuous coverage and ensures secure communications 24/7,' Pan told Chinese state broadcaster CCTV. He had previously told Chinese media that long-distance quantum communication through fibre-optic cables was limited by signal loss.

China scientists put direct quantum communications tech to test in space flight
China has tested how the core components of a quantum-based network might withstand the rigours of space travel, in what is believed to be the start of efforts to build an integrated space-ground system for ultra-secure communications that do not need encryption keys. A laser module and a phase encoding device, developed at the Beijing Academy of Quantum Information Sciences, were on board a Yuanxingzhe-1 rocket that reached 2.5km (1.55 miles) during a two-minute vertical flight testing its reusability last Thursday. 'The launch mainly tested the robustness of the modules against various environmental stresses encountered during rocket ascent, such as vibration and radiation,' the academy said on its official social media account on Wednesday. The test marked a key step in China's transition from experimental validation to the construction of a fully integrated space-air-ground quantum secure direct communication (QSDC) network, the academy added. First proposed by Chinese physicists in 2002, QSDC is considered complementary to another form of quantum secure communication, known as quantum key distribution (QKD). While QKD involves generating encryption keys for use over conventional communication channels, QSDC skips the key-sharing step and sends the actual message directly through a quantum channel. This makes the system more efficient and, in principle, more secure, which has led to some experts referring to QSDC as the 'ultimate form' of secure communication.

China team triples distance record set by direct quantum communication founder
Chinese scientists have achieved a record in quantum-based secure direct communications – trebling the distance of a multi-user network to around the same length as a drive from Paris to Brussels, according to a new paper. While the transmission rate is still too low to handle images, the researchers at Shanghai Jiao Tong University said the 300km (186 miles) optical fibre network was theoretically scalable, showing the viability of this kind of quantum network. According to the paper, published in the May issue of the peer-reviewed Science Bulletin, the quantum secure direct communication (QSDC) network uses multiple lasers or pumps to send paired photons between users, with added noise to help hide the signals. 'The transmission distance or the number of users acts as a constraint on the construction of long-distance, large-scale quantum communication networks,' the researchers said in the paper. 'The realisation of a 10,000km-level quantum communication network containing hundreds or thousands of users represents a significant challenge that requires urgent attention,' they added. There are three main forms of communication that take advantage of quantum physics phenomena to securely send data using particles – typically photons – along optical fibre cables.
