who is and what has an Israeli computer guru come to do in the country

It is not all to do the best mobile, the best search engine or the best online shopping system. There is another race today in the world of technology: to build bigger and better quantum computers.

Abstract sound? A lot of “laboratory”? Yes. But it is the current obsession of the technological giants who accompany us in our daily activities: Google, IBM and Amazon. Not everything is even in the United States. Israel also just unveiled its first quantum computer.

These computers have the potential to perform huge information processing tasks which are beyond the reach of more advanced classical computers. And they may also have an unexpected ability to store information.

If the construction of these more “sensitive” systems materializes, it would be like reset the field of information technology. That complex skill level is known as “the quantum advantage”.

Is this goal very far from our country? No.

Clarione interviewed Professor Roee Ozeri, head of the team that created it at the Weizmann Institute of Sciences, in Rehovot, 30 kilometers from Tel Aviv, who visited Buenos Aires and met at UBA those who know more about quantum , to bet on the future and very close to us.

The idea is to advance in a technology exchange and even offer scholarships for local scientists. It is not just to know that at the top of the Israeli quantum field, in the Weizmann factories, at least 10 Argentines.

“This is a race between academic laboratories and institutions, but also between companies and countries. Several countries invest huge sums of money to facilitate quantum technologies. This is something disruptive,” begins Ozeri.

Ozeri today is “the Quantum Professor” in Israel. This expert became a quantum pioneer 15 years ago when he returned from the United States after doing postdoctoral research in David Wineland’s Nobel Physics team in 2012.

What is the goal in the quantum race? “The goal is to build a large-scale quantum computer, with trillions of quantum bits. And that doesn’t depend on noise and error (meaning more investment is needed). The players are now in the US, China, the Union. Europe – which has launched massively funded programs to advance on the ground – and in Israel, “he says.

It is not a detail that puts “errors” and “noises” in the same sentence. One of the biggest challenges in developing quantum computers is finding ways to do it attenuate the effect of noise in quantum systems. Since information is extremely “fragile” (susceptible to change), noise is its greatest nemesis. He meddles in the construction of large and complex systems.

In the region, Kuatomu was the first quantum computer since 2021, in Brazil.

Two noise-suppressing innovations have already been successfully implemented in the quantum computer they built in that Israeli lab. One has passed laser pulse.

It’s been a little over five years since the tech giants got into this race, but with huge investments and wholly owned devices, they are already ahead. In fact, the largest quantum computers were built by multinationals and star ups. Not from universities.

How does the world benefit from quantum computers? It should generate many “practical” applications. From the drawing by unbreakable codes (anti-hacking) and forecasting fluctuations in financial markets, accelerating the development of new drugs, materials and artificial intelligence systems.

An example in Health? The creation of a drug would no longer be based on the classic “trial and error”, the drug would be created, let’s say, directly. “Because a quantum computer could design large molecules, which are quantum systems, too complex for ordinary computers and are what we need to discover new drugs or medical treatments,” he explains.

Large molecules must also be designed for food safety, fertilizers (more effective and harmless) and other chemical materials. Furthermore, quantum already has the short-term goal of optimizing day-to-day processes such as traffic in big cities, logistics and finance.

Are there any benefits of quantum computers that we are already taking advantage of today? “Yes, but marginally”says Ozeri. “Quantum computers are still relatively small. They need to grow in size and performance to have a wider reach, more commercial and other value.” The computer he developed is not for commercial purposes, but for research purposes only.

IBM has a quantum cloud service which, for example, is already used in the UK optimize the supply of renewable energy. What you buy is the running time, the use of the computer. Amazon also has its own cloud service. The quantum, therefore, is approaching.

What did the “Quantum Professor”, who is also Weizmann’s Vice President, bring to Argentina? Strengthen the bond with scientists in all academic fields of science, beyond the qubit. Like the institute’s focus on solutions to climate change.

At the end of the month they will sign an agreement with the Argentine Ministry of Science and Technology for funding postdoctoral studies at the Israeli institute. “We will all win. Israel will get Argentine talent, which is brilliant, and the idea is that they return to the country with the knowledge that they also acquire in Israel,” she says.

Returning to the quantum, Ozeri met Christian Schmiegelow, physicist, professor and researcher at the Department and Institute of Physics of UBA and Conicet on Tuesday, who directs the Laboratory of Ions and Cold Atoms. His colleague “silver”.

How do you see local quantum technology? “They use the same technology I use in Israel. My country is Argentina share the same challenges in the quantum race: we are not as big as the United States and China and we need the resources to invest in this field. That’s why I think that improving relations and collaboration between countries like ours is important “.

The ABC of the quantum

how much is the science of the little one. And, at the very least, a large-scale quantum computer will allow us to better understand nature.

What’s the benefit? Unlike today’s most advanced computers, which are limited by the limitations of classical physics, quantum computers obey a completely different set of laws: those of quantum mechanicsthat rule the microscopic world.

People, dogs, or even bits – the basic units of information in classical computing – can only be in one place at a time. Quantum bits, called qubits, can be simultaneously in more than one location or statewhich allows you to perform multiple calculations in parallel.

This shakes our common sense, makes everything seem “abstract”, but it is the key to opening the door to “great computing power”. AND Yalla, says the physicist, to imitate our “Dale!” Argentine.

Now, the more “complex” to understand. Just as bits can move between two states, 0 and 1, qubit ion-based can switch from one state to another, defined by different flight paths of an electron around the atomic nucleus.

Today’s Weizmann computer is a machine of cinco qubitmore or less the level reached by the version of IBM when the company started offering quantum computing as a cloud service.

WeizQC, the “largest” computer already built in Ozeri’s laboratory, is programmed to run on 64 qubits. It is expected to demonstrate the quantum advantage so far achieved only with computers built in two labs: at Google and the China University of Science and Technology.
