Quantum computing has become the buzzword of the early 21st century. From the Western world to Asia, everyone is trying to get a head start in this futuristic technology. It seems the Chinese have, for the next week at least, taken the lead. Scientists from China have managed to entangle 18 optical quantum bits – a vital achievement that will hugely boost quantum computing speeds.
Entangling the highest possible number of quantum bits can result in a massive increase of quantum computing speeds. Scientists, though, have to deal with major challenges in their attempts to entangle such large numbers of quantum bits.
A team of scientists from China managed, for the first time, to entangle 18 quantum bits by using a novel technology known as the ‘multi-degrees of freedom photon control’ method.
A professor with China’s University of Science and Technology, Lu Chaoyang, said that if one was able to control a photon’s third degree of freedom that would amount to tripling it. The control of higher degrees of freedom, he added, was another great way for them to further boost the controllable quantum bit count. Chaoyang continued by saying that, to attain the entanglement of a large number of quantum bits, they have adopted a variety of approaches at the same time.
This achievement, Chaoyang concluded, can prove useful in high-efficiency, large-scale quantum information applications, and could be seen as a breakthrough in the development of quantum computers that might surpass the fastest supercomputers of our era.
