Nvidia positions for quantum computing with new products – Reuters

March 21 (Reuters) - Nvidia Corp (NVDA.O), the computing company powering the bulk of artificial intelligence, is positioning itself as a key player in quantum computing with the launch of new software and hardware.

On Tuesday at its developer conference GTC, Nvidia unveiled CUDA Quantum, a platform for building quantum algorithms using popular classical computer coding languages C++ and python. The program would help run the algorithm across quantum and classical computers depending on which system is most efficient in solving the problem.

The new platform is named after CUDA, the software most AI developers use to access Nvidia's graphics processing unit (GPU) and which has given Nvidia chips a huge competitive edge.

"CUDA Quantum will do the same for quantum computing, enabling domain scientists to seamlessly integrate quantum into their applications and gain access to a new disruptive computing technology," said Tim Costa, Nvidia's director of HPC and quantum.

One difference, Costa said, is while CUDA is proprietary, CUDA Quantum is open source and was developed with input from many quantum computing companies.

Nvidia also launched a new hardware system called DGX Quantum to connect the quantum computer with classical computers. It was designed in partnership with Israeli-based startup Quantum Machines whose hardware communicates with quantum processors.

"We see more and more demand to integrate these quantum computers with standard computers," said Itamar Sivan, co-founder and CEO of Quantum Machines.

While quantum computers could potentially speed up some calculations millions of times faster than the fastest supercomputer, it is still uncertain when that would happen. And even when they become good enough to be useful, they would have to be paired with powerful digital computers to operate, said Sivan.

"All quantum today is research, not production, and that isn't going to change next week," said Costa. With DGX Quantum, researchers will be able to develop hybrid applications and critical methods for quantum computing's future, he added.

From ChatGPT to Quantum Computing, New Tech Could Reshape … – Foreign Policy

More than a year into Russias war of aggression against Ukraine, there are few signs the conflict will end anytime soon. Ukraines success on the battlefield has been powered by the innovative use of new technologies, from aerial drones to open-source artificial intelligence (AI) systems. Yet ultimately, the war in Ukrainelike any other warwill end with negotiations. And although the conflict has spurred new approaches to warfare, diplomatic methods remain stuck in the 19th century.

More than a year into Russias war of aggression against Ukraine, there are few signs the conflict will end anytime soon. Ukraines success on the battlefield has been powered by the innovative use of new technologies, from aerial drones to open-source artificial intelligence (AI) systems. Yet ultimately, the war in Ukrainelike any other warwill end with negotiations. And although the conflict has spurred new approaches to warfare, diplomatic methods remain stuck in the 19th century.

Yet not even diplomacyone of the worlds oldest professionscan resist the tide of innovation. New approaches could come from global movements, such as the Peace Treaty Initiative, to reimagine incentives to peacemaking. But much of the change will come from adopting and adapting new technologies.

With advances in areas such as artificial intelligence, quantum computing, the internet of things, and distributed ledger technology, todays emerging technologies will offer new tools and techniques for peacemaking that could impact every step of the processfrom the earliest days of negotiations all the way to monitoring and enforcing agreements.

Although the well-appointed interiors of Viennas Palais Coburg and Genevas Hotel President Wilson will likely remain the backdrop for many high-level diplomatic discussions, the way parties conduct these negotiations will undoubtedly change in the years ahead. One simple example is the need for live language interpreters. The use of automated language processingas exemplified by Googles language-translating glassescould smooth negotiations, reducing the time spent on consecutive interpretation.

While some tools will speed negotiations, others will better inform diplomats ahead of talks. As Nathaniel Fick, the inaugural U.S. ambassador at large for cyberspace and digital policy, recently quipped, briefings generated by the AI-powered ChatGPT are now qualitatively close enough to those prepared by his staff. As large language models improve, AI will be able to search and summarize information more quickly than a team of humans, better preparing diplomats to enter negotiations.

Although these systems will need some degree of human oversight, allied parties can also compare notes, leveraging their respective AI systems. As more and more parties develop their own AI, we could see AI hagglebotscomputers that identify optimal agreements given a set of trade-offs and intereststake on a key role in negotiations. Ever more sophisticated AI systems may even one day reach a level of artificial general intelligence. Such systems could upend our understanding of technology, allowing AI to become an independent agent in international engagements rather than a mere tool.

As negotiations begin, parties may augment their delegations with AI, providing real-time, data-informed counsel throughout discussions. IBMs Cognitive Trade Advisor has already assisted negotiators by responding to questions about trade treaties that might otherwise require days or weeks to answer.

New technologies also allow countries to solicit citizen input more easily in real time. More than a decade ago, Indonesia pioneered a platform called UKP4, allowing everyday citizens to submit complaints about anything from damaged infrastructure to absent teachers. Although technology can be misused for manipulation and misinformation, artificial intelligence can also serve as a powerful tool to identify these misbehaviors, creating an ongoing struggle in the arms race between AI that will help and AI that will harm.

Intelligent systems can also help negotiators test various positions and scenarios in a matter of minutes. During the first round of Iran nuclear negotiations, a team at the U.S. Energy Department built a replica of an Iranian nuclear site to test every permutation of Iranian nuclear enrichment and development. In the future, an AI system will be able to run similar scenarios and virtual experiments faster and at a much lower cost.

When I worked on then-U.S. Secretary of State John Kerrys team negotiating the Joint Comprehensive Plan of Action (JCPOA) in 2014 and 2015, diplomats would meet in a variety of configurationsfrom large plenaries to one-on-one sessionstrying to discover the intentions behind the positions each side took and discern even minor differences among individual negotiators. While traditionally the privy of the espionage community, computer vision can now aid in this effort, identifying micro-expressions and other emotions by analyzing videos of negotiations. Even if diplomacy remains an art, it will increasingly rely on hard science.

When negotiators reach an agreement, they need to secure the support of their capitals and leadership, creating the need for secure communication. Negotiators have long faced the risk of spies and leaks and are now more exposed than before to the threat of intercepted calls and cybersecurity breaches.

New technology can both secure communication and put it at risk. Most strikingly, powerful quantum computers are likely to one day crack present-day encryption. The furor caused by the WikiLeaks revelations would pale in comparison to the bedlam that could unfold as foreign intelligence agencies decrypt thousands of confidential diplomatic cables.

As of today, many intelligence agencies are likely already intercepting and storing cables with the hope of decrypting them once they develop the requisite technological capabilities. In response, countries have developed new techniques to ensure the integrity of diplomatic communication through post-quantum encryption. In a December 2022 demonstration, French President Emmanuel Macron sent the French diplomatic services first quantum-secure telegram.

After parties announce a deal, technology can still play a role in ensuring their agreement enters into force. When the JCPOA went into effect in January 2016, the United States had difficulty releasing Iranian assets frozen after the revolutionbanks were still afraid to transfer money for fear of running afoul of the sanctions regime. In the end, the U.S. government delivered $1.7 billion in cash to Iran, flying $400 million on pallets to Tehran through Switzerland.

Distributed ledger technology has the potential to transparently ensure parties receive compensation and could be used to openly transfer funds while keeping in place sanctions for other purposes. Already, blockchain is showing its promise across a variety of use cases, including transferring information securely out of Ukraine. Working together with social enterprise company Hala Systems, a lab at Stanford University has used blockchain to document Russian war crimes, ensuring that original evidence of war crimes cannot be manipulated.

After agreement and implementation, monitoring is key to ensuring an agreement holds. In 2015, Iran agreed to a monitoring regime of unprecedented rigor. As Kerry explained at the time, Irans nuclear program will remain subject to regular inspections forever. In the future, the internet of thingsor the ability for items of daily use to be connected to the internetmay make such inspections far more effective by creating many new data points. Teams at Los Alamos National Laboratory, for example, have already used AI to detect signs of nuclear explosive tests by relying on data from international sensor networks.

Remote sensing can also play a role in ensuring parties follow through on their commitments. For example, once the exclusive domain of intelligence agencies, a team at Stanford has now used open-source geospatial imagery to monitor activity at Irans nuclear facility in Natanz. Once quantum sensing matures, it will become even more difficult for malicious actors to disguise their activities. Quantum sensors have already proven successful at mapping underground tunnels and identifying seismic activity. Granted, some of these applications are still far in the future; in any upcoming negotiations, monitoring will have to rely on more traditional methods. But the promise of these new technologies is vast.

Although our ways of waging war have evolved, our ways of waging peace have not yet made similar strides. Ukraines defense has laid bare the importance of bringing innovation to the battlefield. Its success at the negotiating table will be in no small part a result of technological innovation too.

Researchers have discovered a way to "translate" quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking.

The research was published in the journal Nature on Wednesday. It represents a new way to convert quantum information from the format used by quantum computers to the format needed for quantum communication.

Photonsparticles of lightare essential for quantum information technologies, but different technologies use them at different frequencies. For example, some of the most common quantum computing technology is based on superconducting qubits, such as those used by tech giants Google and IBM; these qubits store quantum information in photons that move at microwave frequencies.

But if you want to build a quantum network, or connect quantum computers, you can't send around microwave photons because their grip on their quantum information is too weak to survive the trip.

"A lot of the technologies that we use for classical communicationcell phones, Wi-Fi, GPS and things like thatall use microwave frequencies of light," said Aishwarya Kumar, a postdoc at the James Franck Institute at University of Chicago and lead author on the paper. "But you can't do that for quantum communication because the quantum information you need is in a single photon. And at microwave frequencies, that information will get buried in thermal noise."

The solution is to transfer the quantum information to a higher-frequency photon, called an optical photon, which is much more resilient against ambient noise. But the information can't be transferred directly from photon to photon; instead, we need intermediary matter. Some experiments design solid state devices for this purpose, but Kumar's experiment aimed for something more fundamental: atoms.

The electrons in atoms are only ever allowed to have certain specific amounts of energy, called energy levels. If an electron is sitting at a lower energy level, it can be excited to a higher energy level by hitting it with a photon whose energy exactly matches the difference between the higher and lower level. Similarly, when an electron is forced to drop to a lower energy level, the atom then emits a photon with an energy that matches the energy difference between levels. A diagram of the electron energy levels of Rubidium. Two of the energy level gaps match the frequencies of optical photons and microwave photons, respectively. Lasers are used to force the electron to jump to higher levels or drop to lower levels. Credit: Aishwarya Kumar

Rubidium atoms happen to have two gaps in their levels that Kumar's technology exploits: one that exactly equals the energy of a microwave photon, and one that exactly equals the energy of an optical photon. By using lasers to shift the atom's electron energies up and down, the technology allows the atom to absorb a microwave photon with quantum information and then emit an optical photon with that quantum information. This translation between different modes of quantum information is called "transduction."

Effectively using atoms for this purpose is made possible by the significant progress scientists have made in manipulating such small objects. "We as a community have built remarkable technology in the last 20 or 30 years that lets us control essentially everything about the atoms," Kumar said. "So the experiment is very controlled and efficient."

He says the other secret to their success is the field's progress in cavity quantum electrodynamics, where a photon is trapped in a superconducting, reflective chamber. Forcing the photon to bounce around in an enclosed space, the superconducting cavity strengthens the interaction between the photon and whatever matter is placed inside it.

Their chamber doesn't look very enclosedin fact, it more closely resembles a block of Swiss cheese. But what look like holes are actually tunnels that intersect in a very specific geometry, so that photons or atoms can be trapped at an intersection. It's a clever design that also allows researchers access to the chamber so they can inject the atoms and the photons.

The technology works both ways: it can transfer quantum information from microwave photons to optical photons, and vice versa. So it can be on either side of a long-distance connection between two superconducting qubit quantum computers, and serve as a fundamental building block to a quantum internet.

But Kumar thinks there may be a lot more applications for this technology than just quantum networking. Its core ability is to strongly entangle atoms and photonsan essential, and difficult task in many different quantum technologies across the field.

"One of the things that we're really excited about is the ability of this platform to generate really efficient entanglement," he said. "Entanglement is central to almost everything quantum that we care about, from computing to simulations to metrology and atomic clocks. I'm excited to see what else we can do."
