As large language models (LLMs) continue their rapid evolution and domination of the generative AI landscape, a quieter evolution is unfolding at the edge of two emerging domains: quantum computing and artificial intelligence. A growing cohort of researchers and companies are now exploring whether principles of quantum computing can address some of the limitations facing today's AI infrastructure, particularly around scalability, efficiency, and reasoning complexity.
One of the more notable developments comes from Dynex, a Liechtenstein-based firm that recently unveiled its Quantum Diffusion Large Language Model (qdLLM) as a finalist in the SXSW 2025 innovation awards. The company claims that its qdLLM can generate genAI outputs faster and more efficiently than traditional transformer-based systems that depend on current technology infrastructure.
How does this compare to other emerging approaches, and what does it mean for the broader future of AI?
At its core, quantum computing differs from classical computing by leveraging quantum bits (qubits), which can exist in multiple states simultaneously thanks to quantum superposition. This allows quantum computers to evaluate a vast number of potential solutions in parallel, potentially offering advantages in tasks that require large-scale optimization, simulation, or pattern recognition.
In the context of AI, researchers have explored how quantum properties might improve tasks like natural language processing, machine learning optimization, and model training efficiency. However, most of these efforts remain at an early stage. For example, IBM and MIT have studied how hybrid quantum-classical models could reduce training time for specific deep learning tasks, while startups like Zapata AI are experimenting with quantum-enhanced models for sentiment analysis and forecasting.
Against this backdrop, Dynex's approach introduces a new architecture that uses quantum-inspired algorithms to run LLMs more efficiently via decentralized hardware.
Unlike transformer-based models that generate responses one token at a time using autoregressive techniques, Dynex's qdLLM is built on a diffusion model that creates output tokens in parallel. According to Dynex, this approach is more computationally efficient and yields better contextual consistency.
'Traditional models like GPT-4 or DeepSeek work sequentially,word after word,' says Daniela Herrmann, Co-founder and Global Head of Leadership at Dynex. 'qdLLM works in parallel. It thinks more like the human brain,processing patterns all at once. That's the power of quantum.'
Several academic projects, including those at Stanford and Google DeepMind, as well as initiatives out of the major AI technology providers have recently begun exploring diffusion-based transformers.
Dynex further differentiates itself by integrating quantum annealing, a form of quantum optimization, to improve token selection during text generation. The company claims that this improves coherence and reduces computational overhead compared to conventional LLMs.
One unique feature of Dynex's model is its reliance on a decentralized network of GPUs that emulate quantum behavior, rather than requiring access to actual quantum hardware. This design allows the system to scale to what Dynex describes as up to one million algorithmic qubits.
Herrmann explains, 'Any quantum algorithm, for example qdLLM, is being computed on a decentralised network of GPUs which are efficiently emulating the quantum calculations.'
This type of emulation draws some parallels to the work of TensorFlow Quantum (by Google and X), which also simulates quantum circuits on classical hardware to prototype algorithms. Similarly, a number of technology startups and vendors are developing platforms to simulate quantum logic at scale before physical hardware is ready.
In addition to software, Dynex plans to introduce its own neuromorphic quantum chip, named Apollo, by 2025. Unlike superconducting quantum chips that require cryogenic cooling, Apollo is designed to run at room temperature, supporting integration into edge devices.
'Using neuromorphic circuits allows Dynex to emulate quantum computing on a large scale, of up to 1 Million algorithmic qubits,' Herrmann explains. 'Dynex will start producing actual quantum chips, which are also based on the neuromorphic paradigm.'
Dynex states that qdLLM achieves 90% smaller model sizes, is 10x faster, and uses only 10% of the GPU resources typically required for equivalent tasks. These are significant claims, particularly given increasing scrutiny on AI's energy usage.
'The efficiency and parallelism of the quantum algorithm reduces the energy consumption, because it is 10x faster and requires only 10% of the number of GPUs,' says Herrmann.
While independent verification is still needed, Dynex's approach echoes efforts by Cerebras Systems, which has created wafer-scale chips that use less energy per training task. Another example is Graphcore, whose intelligence processing units (IPUs) aim to reduce the energy footprint of AI workloads through specialized parallel architecture.
Dynex reports that qdLLM is performing strongly against leading models,including ChatGPT and Grok, on benchmarks requiring strong reasoning. Though public benchmark data has not yet been released, the company states it will publish comparative studies as it moves closer to a 2025 market launch. Until peer-reviewed benchmarks are available, Dynex's performance assertions remain anecdotal but intriguing.
'We are publishing qdLLM benchmarks regularly and have demonstrated that certain questions, which require strong reasoning, cannot be correctly answered by ChatGPT, Grok or DeepSeek,' Herrmann notes.
In the long term, Dynex sees quantum computing becoming central to the AI field.
'We think that quantum will be dominating AI in the next 5 years,' Herrmann says.
That projection remains speculative, though it's not without precedent. Analysts from McKinsey, BCG, and Gartner all note that quantum computing could dramatically improve optimization and simulation tasks, but likely not until beyond 2030 for most use cases. A more measured view suggests that quantum-AI hybrids will emerge first in niche applications, such as drug discovery, financial risk modeling, or cybersecurity.
For now, Dynex stands among a growing field of players experimenting with quantum-enhanced or quantum-inspired AI methods. Whether their decentralized, diffusion-based qdLLM can scale beyond benchmarks remains to be seen, but its arrival signals that the search for new foundations in AI is far from over.

Major supermarket chain closing 60 locations
We're in the midst of very strange economic times. On the one hand, unemployment is low, and the economy is supposedly in good shape. Inflation is also cooling. Don't miss the move: Subscribe to TheStreet's free daily newsletter So then why are so many people facing higher costs than ever and struggling to keep up with their bills? Related: Walmart makes bold move to help inflation-battered consumers Part of the problem stems from the fact that while inflation isn't horrendously elevated these days, it's been sitting at higher-than-average levels for years. And as a result, a lot of people have been paying more for essentials since 2021. Unfortunately, tariff policies could make matters even worse as the year progresses. Right now, there's a pause on tariffs. But once it ends, we could see the price of all sorts of products increase. And one key category that's likely to rise is food. This stretch of pesky inflation has changed the way a lot of people spend their money. These days, many can't afford to shell out extra for restaurant meals, so they're turning to their neighborhood supermarkets for groceries instead. Related: Costco quietly pulls popular product, upsets fans This trend is clearly bad news for the restaurant industry. But it's good news for grocery chains. Even if food costs increase once tariffs take hold, consumers will have no choice but to stock their pantries and fridges. And as it gets even costlier to dine at restaurants, the demand for groceries could increase. Given these trends, you'd think grocery stores these days would be making plans to open their doors, not close them. And to be fair, some of them are. Aldi, for example, is working on an expansion strategy that will add 225 stores to its lineup by the end of 2025. But one major supermarket chain is doing the opposite. Kroger, one of the largest supermarket chains in the country, is making plans to close 60 stores in the next 18 months. Related: Costco, Trader Joe's have one huge problem customers hate The Cincinnati-based grocer says it's specifically looking to shutter locations that have been underperforming. The move should free up money on Kroger's balance sheet to move forward with other plans, such as remodeling existing stores in need of a refresh. The company said earlier this year that it's looking to invest in an improved customer experience. Kroger is also looking to expand its selection of private-label products. At a time when consumers are looking to conserve funds as much as possible, offering up store brand products at competitive prices makes sense for Kroger. So does shuttering less profitable locations, to a degree. But if demand for groceries picks up, Kroger could end up regretting the decision to close some of those stores, especially if it means losing customers to competitors. At the end of its most recent fiscal year, Kroger operated over 2,700 stores across 35 states. The 60 planned closures represent just a small portion of the company's overall footprint.

Dog's ashes among dozens to rocket into orbit this weekend
Bone voyage! A beloved dog named Franz will take his final leap this weekend — into Earth's orbit. The yellow labrador's ashes will be on board the inaugural Perseverance Flight from Texas-based Celestis Inc., which is scheduled to launch around 5:30 p.m. Sunday from Vandenberg Space Force Base in Santa Barbara, CA. 4 Franz was like a sibling to Elizabeth Moore before he died at age 13 in October 2020. Celestis, Inc Carrying a total of 166 titanium and aluminum capsules, each about a quarter to a half-inch in size and filled with DNA or cremated remains, the 23-foot-tall SpaceX Falcon 9 rocket will take two trips around Earth's low orbit at a mind-boggling 17,000 mph. The space flight will last about three hours before the rocket — still carrying its priceless payload — re-enters the atmosphere and lands in the Pacific Ocean somewhere between Alaska and Hawaii, according to Celestis CEO and co-founder Charles Chafer. A recovery ship, which was already out at sea Friday in anticipation of the launch, 'will track the incoming rocket, hopefully get a visual on it, and then go pick it up out of the ocean,' Chafer explained. 4 The Texas-based company Celestis Inc.'s inaugural Perseverance Flight will take two trips around Earth's Lower Orbit after blastoff on Sunday. The capsules will first be transported to Germany, then, within two months, distributed back to the families, who each paid a whopping $3,500 to send their loved one to the stars. While the price to send Franz on the voyage was 'a lot more' than the pooch itself, his owner, Harvin Moore, said with a laugh, it was only fitting for the 'space-fanatic' Moore family to send the pup beyond the stratosphere. 'He was the best dog, just so soft and nice and loved hugs,' recalled Moore, 60, who lives in Dripping Springs, Texas, just outside Austin. 4 The Moore family can't wait to watch their beloved pooch go galactic. Celestis, Inc Franz, who was 13 when he died in October 2020, was more like a sibling than a pet to Moore's now 26-year-old daughter, Elizabeth, and son, Quinn, 21, he said. Now, the family can't wait to watch the good boy go galactic. 'The emotional power of being with a group of people who are celebrating the life of a loved one in this way … it's amazing. It's nothing we'll ever forget,' said Moore. 'It's just pure joy.' 4 The Perseverance Flight will carry a total of 166 titanium and aluminum capsules, ranging in size from a quarter to a half-inch, filled with DNA or cremated remains. Celestis, Inc 'Many people whose ashes and DNA are flying are people that always wanted to go to space in their lifetime but were never able to do that. It also helps families move from feelings of grief to joy,' Chafer said. The cremated remains of Wesley Dreyer — an aerospace engineer who helped investigate the cause of the Space Shuttle Challenger's shocking explosion after takeoff on Jan. 28, 1986 — will also be on board the Perseverance Flight, as well as DNA from a living, 3-year-old German boy.
