While tunneling reactions are remarkably hard to predict, a group of researchers were able to experimentally observe such an effect, marking a breakthrough in the field of quantum chemistry.

Tunnel Effect

Predicting tunnel effects is very difficult to pull off. The mechanically exact quantum description of chemical reactions that cover over three particles is quite hard. If it covers over four particles, it is almost impossible to pull off. In order to stimulate the reactions, scientists use classical physics but have to push aside the quantum effects. However, EurekAlert reports that there is a limit to classically describing these chemical reactions. What, then, is the limit?

In an interview with EE Times, Classiq CEO Nir Minerbi said Classiq’s academic program is an essential part of its broader strategy to expand the platform’s reach and promote the quantum computing business.

“We believe that offering this program will give students the tools and knowledge they need to learn practical quantum software-development skills while also providing researchers with a streamlined means of developing advanced quantum computing algorithms capable of taking advantage of ever more powerful quantum hardware,” he said. “In addition, our program enables students and researchers to test, validate and run their quantum programs on real hardware, providing valuable real-world experience. Ultimately, we think that our academic program will have a significant impact on the quantum computing community by promoting education and research in the field—and helping to drive innovation and progress in the industry.”

Classiq and Microsoft are among the top companies developing quantum computing software. The quantum stack developed by the firms advances Microsoft’s vision for quantum programming languages, which was published in the 2020 issue of Nature.

Tunneling reactions in chemistry are difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four particles it is almost impossible. Theorists simulate these reactions with classical physics and must neglect quantum effects. But where is the limit of this classical description of chemical reactions, which can only provide approximations?

Roland Wester from the Department of Ion Physics and Applied Physics at the University of Innsbruck has long wanted to explore this frontier. “It requires an experiment that allows very and can still be described quantum-mechanically,” says the experimental physicist. “The idea came to me 15 years ago in a conversation with a colleague at a conference in the U.S.,” Wester recalls. He wanted to trace the quantum mechanical tunnel effect in a very simple reaction.

Since the tunnel effect makes the reaction very unlikely and thus slow, its experimental observation was extraordinarily difficult. After several attempts, however, Wester’s team has now succeeded in doing just that for the first time, as they report in the current issue of the journal Nature.

Skyrmions are extremely small with diameters in the nanoscale, and they behave as particles suited for information storage and logic technologies. In 1961, Tony Skyrme formulated a manifestation of the first topological defect to model a particle and coined it as skyrmions. Such particles with topologically stable configurations can launch a promising route toward establishing high-density magnetic and phononic (a discrete unit of quantum vibrational mechanical energy) information processing routes.

In a new report published in Science Advances, Liyun Cao and a team of researchers at the University of Lorraine CNRS, France, experimentally developed phononic skyrmions as new topological structures by using the three-dimensional (3D) hybrid spin of . The researchers observed the frequency-independent spin configurations and their progression toward the formation of ultra-broadband phononic skyrmions that could be produced on any solid structure.

OAKLAND, Calif. Feb 28 (Reuters) — Intel Corp (INTC.O) on Tuesday released a software platform for developers to build quantum algorithms that can eventually run on a quantum computer that the chip giant is trying to build.

The platform, called Intel Quantum SDK, would for now allow those algorithms to run on a simulated quantum computing system, said Anne Matsuura, Intel Labs’ head of quantum applications and architecture.

Quantum computing is a new approach founded on quantum mechanics principles to perform calculations. Unlike classical computers, which store information in bits (either 0 or 1), quantum computers use quantum bits or “qubits” that can exist in multiple states simultaneously. This physics property allows quantum computers to perform specific calculations much faster than classical computers.

The potential applications of quantum computing are vast and include fields such as cryptography, finance and drug discovery. It promises to transform multiple industries and tackle challenges that classical computers cannot solve.

Heat causes errors in the qubits that are the building blocks of a quantum computer, so quantum systems are typically kept inside refrigerators that keep the temperature just above absolute zero (−459 degrees Fahrenheit).

But quantum computers need to communicate with electronics outside the refrigerator, in a room-temperature environment. The metal cables that connect these electronics bring heat into the refrigerator, which has to work even harder and draw extra power to keep the system cold. Plus, more qubits require more cables, so the size of a quantum system is limited by how much heat the fridge can remove.

To overcome this challenge, an interdisciplinary team of MIT researchers has developed a that enables a quantum computer to send and receive data to and from electronics outside the refrigerator using high-speed .

Google scientists said Wednesday they have passed a major milestone in their quest to develop effective quantum computing, with a new study showing they reduced the rate of errors – long an obstacle for the much-hyped technology.

Quantum computing has been touted as a revolutionary advance that uses our growing scientific understanding of the subatomic world to create a machine with powers far beyond those of today’s conventional computers.

However, the technology remains largely theoretical, with many thorny problems still standing in the way – including stubbornly high error rates.
