It is built by the Chinese scientists; theoretically it can do calculations 24,000 times faster than its international counterparts
Another remarkable achievement is achieved by China. They already have the world’s fastest supercomputer (TaihuLight) Now they have developed a quantum computer that can work 24,000 times faster than any existing supercomputer, including TaihuLight.
Other technology organizations like IBM and D-Wace have already manage to build quantum computers of their own, the property which differentiates China’s quantum computer is using multiple photons( the visible particles of light), Five of them specially, and it gives it the computing speed a super boost.
Earlier to this, Pan Jianwei : the research team leader from the University of Science and Technology of China, multi-photon quantum computer is built by him – together with one of his colleagues, Lu Chaoyang, was recognized with developing the world’s best semiconductor quantum dots- based single photon source. An electronically programmable photonic circuit and this photon source made it possible for them to construct their own multi photon quantum computing machine.
Pan Jianwei ‘s device can do calculations 10 to 100 times faster than ENIAC, which was the first electronic digital computer constructed in the 1940s. Yet there is no practical use for it, its ability to calculate the highly complex behavior and movement of photon (traditional computer are unable of doing this) is a clear evidence of the potential of quantum computers.
Conventional machines store and process data in bits that can represent either 0 or 1. Alternatively, quantum machines use qubits (short for quantum bits) that can represent 0, or 1, or 0 and 1 at the same time through the quantum concepts super positioning (being able to exist in two states at once) and entanglement. This property makes a quantum computer extraordinary — it can process data and calculate outcomes concurrently. And the more qubits that can be manipulated, the faster its computing ability becomes.
Reading books in a library is a general resemblance used to explain the concept of quantum. Conventional computing is like reading one book at a time, finishing one before moving on to another. While quantum computing is like reading all the books at the same time.
This presumption has been around for a while, but researchers have yet to figure out the best method that can change this quantum computing vision into a reality.
This is what makes China’s achievement so important. Their newest quantum machine — which they are calling a Boson sampling machine — isn’t just capable to do calculations for five photons; it’s capable to do so at a speed that’s 24,000 times faster than what earlier proof-of-concept experiments showed. Even better, the team says that scaling up their architecture to a higher number of photons is feasible, adding up to its potential to compete and defeat the performance of classical computers.
According to Shanghai Daily, the researcher are trying to be able to manipulate 20 entangled photons by the end of the year. Their work was just published on Nature Photonics.
