Secure networks using quantum key distribution (QKD) could transmit sensitive data for things like financial transactions and provide utmost secrecy for military operations and communications. MANILA, Philippines — China announced it is temporarily closing its borders to non-Chinese nationals from the Philippines in a move to prevent entry of fresh cases of coronavirus disease (COVID-19).

In 2014, there were a similar number of patents filed in the United States and China, but by 2017 China filed almost twice as many, according to Patinformatics. “In the last five years, China has invested very heavily in quantum technologies,” says Robert Young, director of the Lancaster Quantum Technology Centre, and an adjunct professor at the Institute of Fundamental and Frontier Science in Chengdu. The man behind this achievement is Jian-Wei Pan. “We could have a race, but people need to talk and collaborate with each other.”, – Why the iPad Pro won’t save the free-falling tablet market, – Small robots will make farming efficient and kill tractors, – Scientists explain why Hyperloop is so dangerous and difficult, – China wants to make supersonic trains. It’s tempting to paint the development of quantum computing and cryptography as a zero-sum game – China vs America for the global technological crown. “We were only the follower and the learner at the birth of modern information science,” he said. “But influenced by Google and IBM or Intel and Microsoft - all the Chinese e-commerce companies now have their own quantum technology projects.”, By “It’s clear this is going to be the next revolutionary technology, it’s clear there’s going to be a whole plethora of interesting devices and they’re investing in that potential.”. In the US, the big tech companies are focussed on pushing up the qubit-count and bringing down the error rate on quantum computers. Less than an hour later, the satellite passed over Austria and dispatched another data packet to a station near the city of Graz. But it’s not quite like that. What made this event so special was that the keys distributed by the satellite were encoded in photons in a delicate quantum state. The field is fragmenting, with different research groups trying varied approaches, and countries putting their resources behind a diverse range of projects. While money matters, there’s more to China’s success than the bankrolling of satellites and other projects. This means they were far more secure than keys sent as classical bits—a stream of electrical or optical pulses representing 1s and 0s that can be read and copied. Some researchers contacted for this article were en route to South Africa for a collaborative workshop, to share ideas with their international colleagues. Instead of bits – which are either 1s or 0s – quantum computers use qubits, which can exist in more than one state. In August 2016, China sent the world’s first quantum satellite into space from a launchpad in the Gobi Desert. UNTV is a major TV broadcast network with 24-hour programming. “The really exciting thing, and the reason that the Chinese are investing in this is that they don’t know what the potential will be,” says Young. Some Chinese cities are also building municipal networks. Big Chinese tech companies like Alibaba and Baidu are investing heavily in quantum computing, too. “The above-mentioned measures will be assessed in accordance with the evolving situation and any adjustment will be announced accordingly,” the embassy said. A more optimistic view sees China remaining open to the kinds of interchanges that have helped turn it into a quantum superpower, and doing its utmost to profit from a new, quantum-inspired data economy. "I think we have started a worldwide quantum space race," he said. The decision to share it is part of the sovereign rights,” explained Presidential Spokesperson Harry Roque. They won't work, – Inside the intensely political philosophy of the Fallout games, Get the best of WIRED in your inbox every Saturday with the WIRED Weekender newsletter, By admin   •   July 4, 2018   •   14122, Lu Chaoyang, professor with University of Science and Technology of China, leading team on quantum bits research (Image grabbed from Reuters video). Big companies like China Shipbuilding Industry Corporation, one of the country’s largest builders of warships and submarines, are working with universities on quantum projects. Chinese scientists make breakthrough in quantum computing technology. Some of the money will be for a new USTC campus on the same site to train quantum researchers. Looking much further ahead, the technology could one day be used to secure everything from smartphones to laptops. “It’s not good enough to invent a telephone, for example, if it’s just you who has the unit and you have no one to call. That’s why the bulk of China’s initial progress has been in the field of secure quantum communications – through projects such as Micius, as well as a ground-based quantum network in the northern province of Shandong. In the future, the machines could be used to discover new materials and drugs by running simulations of chemical reactions that are too much work for classical computers. In an interview with MIT Technology Review, Pan talked about the importance of international collaboration, but he also made clear that China sees a unique window for it to shape the next meta-shift in the technology landscape. “Our next plan is to surpass the conventional computers using integrated circuits in human history, then surpass the fastest commercial computers of our times, and then surpass the supercomputers. A group of Chinese scientists for the first time entangled as many as 18 quantum bits by adopting a new technology called the multi-degrees of freedom photon control method. Nations, such as China and the US are involved, as well as some of the world's biggest companies and organisations, including: Google, Nasa, Microsoft, Lockheed Martin and Alibaba.
