A so-called quantum particle, he can exist in two places at the same time, and even strangely connect with each other, despite being millions of kilometers apart.
Quantum computers take advantage of the strange properties of elementary particles.
A team from the University of Sussex has transferred quantum information between his computer chips with record speed and precision.
Computer scientists have been trying to build effective quantum computers for over 20 years. Companies such as Google, IBM, and Microsoft are developing simple machines. But according to Professor Winfried Hensinger, who led the research at the University of Sussex, the new development paves the way for systems that can solve complex real-world problems that today’s best computers can’t.
“We now have quantum computers with very simple microchips,” he said. “What we have achieved here is the ability to realize a very powerful quantum computer that can solve some of the most important problems facing industry and society.”
Now the computer solves problems in a simple linear way where he does one calculation at a time.
In the quantum domain, particles can exist in two places at the same time, and researchers hope to take advantage of this property to develop computers that can perform multiple computations simultaneously. Quantum particles can be millions of kilometers apart, combine in strange ways, and even instantly reflect each other’s actions… Again, this could be used to develop much more powerful computers. can.
A stumbling block has been the need to transfer quantum information between chips quickly and reliably. Information is degraded and errors occur. But Professor Hensinger’s team has made a breakthrough that may overcome this obstacle, published in Nature Communications.
The team has developed a system that can move information from one chip to another with 99.999993% reliability and record speed. According to the researchers, this shows that in principle chips can be connected to form a more powerful quantum computer. Professor Michael Cuthbert, director of the newly established National Center for Quantum Computing in Didcot, Oxfordshire and independent from the Sussex Research Group, said in a “very important step to make this development possible”. I explained that there is. But more work is needed to develop a working system, he said.
“To build the kind of quantum computers we will need in the future, we start by connecting chips the size of thumbnails so that we get something the size of a dinner plate. It showed stability and speed. “But to do any realistic and useful calculations, we need a mechanism to connect these plates and scale the machine up to the size of a football field, but the technology to communicate at that scale is not yet available.”
