Quantum IT fleas release major manufacturing obstacles

A startup has proven that its quantum silicon chips can be made on a large scale without losing precision.

The Startup Unsw Sydney Diraq has shown that its quantum chips are not only effective in controlled laboratory conditions, but also maintain performance when produced in real world production. Fleas constantly reach 99% precisionA reference considered essential to make quantum computers practical.

To reach this milestone, the Diraq has teamed up with the interuniversity microelectronic center of Research Institute (IMEC). Collaboration has confirmed that fleas offer the same high reliability when they are produced through standard semiconductor manufacturing processes as in UNSW research laboratories.

According to UNSW engineering teacher, Andrew Dzurak, founder and CEO of Diraq, he had not previously been demonstrated that the level of precision reached in laboratory prototypes – known in quantum calculation As a loyalty, could be successfully reproduced in large -scale manufacturing.

“Now it is clear that the Diraq chips are entirely compatible with the manufacturing processes that have existed for decades.”

World benchmarks

In an article published in NatureThe teams report that devices designed by Diraq and fully designed have obtained more than 99% loyalty in operations involving two quantum bits – or “qubits”. The result is a crucial step towards the scale of quantum processors of Diraq to be carried out, the point where the commercial value of a quantum computer exceeds its operational cost. It is the key metric set out in the quantum benchmarking initiative, a program managed by the Defense Advanced Research Projects Agency in the United States (Darpa) to assess if Diraq and 17 other companies can achieve this objective.

Quantum computers at the level of public services should be able to solve problems out of reach of high performance computers the most advanced available today. But the violation of the threshold of the public services scale requires storing and manipulating quantum information in millions of qubits to overcome errors associated with the fragile quantum state.

“The realization of the scale of public services in quantum IT hinges on the search for a commercially viable means of producing high -scale quantum bits on a large -scale,” said Professor Dzurak.

“The collaboration of Diraq with the IMEC clearly shows that quantum computers based on silicon can be built by taking advantage of the mature semiconductor industry, which opens a profitable path to chips containing millions of knitting while maximizing loyalty.”

The edge of silicon in quantum development

Silicon emerges as the first row of the materials explored for quantum computers – it can pack millions of qubits on a single chip and operates transparently with the micro -cup industry of billions of dollars today, using the methods that put billions of transistors on modern computer chips.

The DIRAQ previously shown that the qubits made in an academic laboratory can reach high fidelity during the execution of logical doors with two qubit, the basic construction block of future quantum computers. However, it was not clear if this loyalty could be reproduced in qubits made in a semiconductor foundry environment.

“Our new discoveries show that Diraq silicon qubits can be manufactured using processes that are widely used in semiconductor foundries, respecting the thresholds of tolerance to the breakdowns in a profitable and compatible with industry,” said Professor Dzurak.

Diraq and IMEC previously shown that the quit made using CMOS processes – the same technology used to build daily computer flea – could carry out single qubit operations with a precision of 99.9%. But more complex operations using two qubits which are essential to reach the scale of public services had not yet been demonstrated.

“This last realization opens the way to the development of a functional functional computer and tolerant entirely to breakdowns which is more profitable than any other qubit platform,” said Professor Dzurak.
