Home Science News UNSW Team Reports Breakthrough in Quantum Computing has indeed proved quite its worth.
UNSW Team Reports Breakthrough in Quantum Computing does make qubits superior to conventional bits as it is in addition to just occupying a 0 or 1 position and they can occupy both at the same time.
UNSW Team Reports Breakthrough in Quantum Computing
A team of scientists from the University of New South Wales (UNSW) in Australia has indeed measured for the first time accuracy of two-qubit operations in silicon – a feat that would indeed enable companies to build a full-scale quantum processor.
Computers today do process information in binary bits that take either a 0 or 1 value while quantum computers tend to depend on the related but superior concept of the qubit.
What does make qubits superior to conventional bits is that in addition to just occupying a 0 or 1 position, as they can occupy both at the same time, what is known in quantum mechanics as the superposition.
All quantum computations can indeed be made up of one-qubit operations and also two-qubit operations. They are the central building blocks of quantum computing.
The research which was published in the prestigious journal Nature, promises quantum computers that would no doubt enable a vastly more powerful and faster way of making calculations than the computing power one has had till date.
In 2015, Dzurak along with fellow researchers built the world’s first quantum logic gate in silicon, so that two qubits could communicate with one another.
A number of groups all across the world have since demonstrated two-qubit gates in silicon but the true accuracy of such a two-qubit gate was unknown.
Fidelity is a critical parameter which does determine how viable a qubit technology is. One can only tap into the tremendous power of quantum computing if the qubit operations are near perfect, with only tiny errors being allowed.
In a study, the team implemented as well as performed Clifford-based fidelity benchmarking which happens to be a technique that can assess qubit accuracy across all technology platforms demonstrating average two-qubit gate fidelity of 98 percent.
Quantum computers will indeed have a wide range of important applications in the future thus appreciating to their ability to perform far more complex calculations at much greater speeds, including solving problems that are indeed simply beyond the ability of today’s computers.
But for most of those important applications, millions of qubits will rather be needed, and one is going to have to correct quantum errors, even when they are small.
The researchers said that silicon as a technology platform is ideal for scaling up to the large numbers of qubits that are needed for universal quantum computing.
In another paper published in the Nature Electronics journal, it was recorded for the world’s most accurate 1-qubit gate in a silicon quantum dot, with a remarkable fidelity of 99.96 percent.
Both Redmi K20 Pro vs Redmi K20 has a lot of similarities, and the Redmi K20 and Redmi K20 Pro sport a triple rear camera setup as well as a mechanized pop-up selfie camera setup.
