A team from the University of Sydney (USyd) working with Microsoft, together with Stanford University in the United States, has announced the development of a miniaturized component trumpeted as essential for the expansion of quantum computing.
According to the University, the work represents the first practical application of a new phase of the material that was discovered for the first time in 2006, "topological insulators", which are materials that function as insulators in most of their structures, but they have surfaces that act as conductors. 19659004] "The manipulation of these materials provides a way to build the circuits necessary for the interaction between quantum and clbadical systems," USyd said in a statement.
As a result, USyd said that they are vital to building a practical quantum computer.
The Sydney team developed a microwave circulator, which acts as a traffic roundabout by ensuring that electrical signals only propagate in one direction, clockwise or counterclockwise, as required.
"Similar devices are found in the base stations of mobile phones and in radar systems, and will be required in large quantities in the construction of quantum computers," the university added.
Usyd explained that previously, an important limitation was that typical circulators are bulky objects the size of a human hand. However, with its miniaturization equipment of the common circulator device by a factor of 1,000, USyd believes that miniaturization paves the way for many circulators to be integrated into a chip and manufactured in the large quantities that will be needed to build quantum computers.
Miniaturization has been achieved by exploiting the properties of topological insulators to decrease the speed of light in the material.
"It's not just about qubits, the fundamental building blocks for quantum machines." The construction of a large-scale quantum computer also needs a revolution in clbadical computing and device engineering, "said Professor David Reilly, leader of the Sydney team.
"Even if we had millions of qubits today, it is not clear if we have the clbadical technology to control them.
" The realization of an enlarged quantum computer will require the invention of new devices and techniques at the clbadical quantum interface ".  Although a practical quantum computer is still within a few years, compact circulators are promoted for use on a variety of quantum hardware platforms, regardless of the particular quantum system used.
Professor Reilly is director of the Microsoft Quantum Laboratory from the University of Sydney, with the multimillion-dollar part of the partnership for a global effort by Microsoft to build the world's first practical quantum computer.
The badociation is located at the Sydney Nanoscience Hub, Station Q, which at a cost of AU $ 150 million will see Microsoft provide equipment, allow the recruitment of new people and helping to develop scientific and engineering talent, as well as helping researchers to progress in their work in the development of quantum technologies.
The approach of Reilly and his team at the Q Sydney station is to take quantum computing out of the lab into the reality world where it can have a genuine impact.
Reilly's team has already demonstrated how quantum spin-off technologies can be used in the vicinity – future to help detect and track early-stage cancers using the quantum properties of nanodiamonds. University scientists have also developed an automatic learning technique to predict the disappearance of quantum computing systems in an attempt to prevent the breaking of quantum bits.
Quantum computing is expected to revolutionize the world, with Australia well positioned to be the first in the quantum finishing line.
Speaking at the recent D61 + Live conference in Melbourne, Professor Michelle Simmons, director of the Center for Quantum Computing and Communications Technology (CQC2T) at the University of New South Wales, said that 40 percent of The entire industry in Australia will be affected by quantum computing.
