Quantum leap from Australian research promises super-fast computing power | technology



An Australian research team led by the famous quantum physicist Professor Michel Simmons has announced a major breakthrough in quantum computing, which researchers hope to deliver much more computational power within a decade.

Simmons, a former Australian of the Year, and her team at the University of New South Wales, reported in a report published in Nature magazine on Thursday that they had managed to reach the first two-cell gate between atomic cubes in silicon, allowing them to communicate with each other 200 times higher than the previous one at 0.8 nanoseconds.

Cubite is a quantum bit. In this project it is made up of single phosphorous atoms in silicon. In standard calculations, the bit can exist in one of two states ̵

1; 1 or 0. For the cubes, it can be 1 or 0 or both simultaneously, which is called a superposition.

By being able to exist in both states simultaneously, qubit can solve problems much faster than bits. This allows for much faster processing than current computers, which means that complex problems can be solved much faster.
The double-cell door functions as a logical gate in traditional calculations, and the UNSW team has achieved faster work by bringing together two atomic cubes more than ever – just 13 nanometers – and real-time

Scanning tunneling microscope was used for insertion of the silicon atoms after the optimum distance between the two cubes has been constructed.

The study was carried out two decades after researchers from Australia decided to build a quantum computer on silicone material.

Simmons told Guardian Australia he was "a pretty bold move" to try to build a silicon quantum computer, but it began to pay off. is still not as far ahead as Google or IBM, who have built up 72 cubic and 50 cubic processors, respectively.

However, the reduction in percent error is key, before quantum computing reaches the scale, and what is quoted in quantum superiority, where quantum computing can solve what can not be solved by today's computers.

When choosing silicon, Simmons said the research team has shown that their atomic circuits have the lowest electrical noise of any system that is still in place

The next stage of the study for the team will be to reach 10 -cabits over the next five years, and we hope to be commercialized within a decade.

Simmons said the work with the UNSW Researchers' Team was "ruthlessly systematic", with no room for error but very rewarding. I think this is one of the key things: we work hard, but we play hard.
