Future quantum computers will make miraculous calculations even for existing supercomputers. Researchers from the swiss federal institute of technology in Zurich eth have shown, for the first time, that quantum systems can be automatically corrected for errors, quickly and continuously allowing the use of quantum systems in practice.
Andreas Wallraff, director of the Quantum Center of the Institute above, says: “The possibility of correcting the quantum computer, which works with quantum bits (qubits) – mistakes quickly and repeatedly is the best step in the way of making a practical quantum computer.”
Because they rely on quantum systems, the operating units of these new computers are very sensitive and must remain kept at temperatures shallow, just above absolute zero.
absolute zero = 273°c below zero.
What is Quantum Computing?
So, Quantum Computing is a rapidly-emerging technology that harnesses the laws of quantum mechanics to resolve problems too complex for classical computers.
Today IBM Quantum types real quantum hardware. Tools Scientists Just Started Imagining 30 Years Ago, Available to hundreds of thousands of developers. Our engineers regularly deliver increasingly powerful superconducting quantum processors and significant advances in classical quantum orchestration and software. This work drives the quantum computing speed and capacity essential to change the world.
These machines are very different from the classical computers that have existed for over half a century. Here’s a primer on this transformative technology.
Why do we want Quantum Computers?
For some issues, supercomputers aren’t that super.
When scientists and engineers encounter complex problems, They look to supercomputers. These are vast classical computers. They often use thousands of traditional CPU and GPU cores. However, even supercomputers struggle to solve certain kinds of problems.
If supercomputers are stuck, it’s probably because big classic machines were asked to solve very complex problems. When traditional computers fail, it’s often because of complexity. Complex problems are problems with many variables that interact in complex ways. Modelling the behaviour of individual atoms in molecules is a complex problem as all the different electrons interact. Arranging ideal routes for hundreds of tankers in the worldwide shipping network is also complicated.
Error corrections are existence investigated
Error corrections investigate and explore, and the system under study uses 17 cube bits and operates at a temperature of no more than 0.01 kelvin, very low above absolute zero.
In this heat, the kibbutz is an excellent carrier of electricity that passes through them without resistance. Nine of those 17 cups make up a three-line square. All accounts pass on those nine units, the computer mastermind.
The remaining eight units act as operational control and allow system errors to be under detection. If the cubes can see errors, the system will correct itself. Thanks to this process, the computer can access problems affecting the plan to remain.
“We don’t currently correct errors in the cubes directly. But this is not necessary for most calculations,” says Sebastian Kreiner. And also, co-author of the research paper.
The new research confirms that a fault-correcting system is feasible and practical. But we are not at a time when the quantum computer is still infallible.
What Does the Paper State for Quantum Computers?
The paper also states: “through high-performance, fast and frequent quantum cycles to correct errors – along with developments in ion fisheries – we have shown that error-correcting quantum computing is possible.”
It is not the only approach to correcting errors. As there have recently been some other potential quantum solutions.
Therefore, today’s quantum computer may not exist in practice. But scientists spare no effort in addressing the dilemmas in their way.
