Chinese scientists have developed a programmable quantum computing prototype called Jiuzhang 4.0 that has set a new world record for optical quantum information technology, according to a study published May 13 in the journal Nature.
Led by the University of Science and Technology of China (USTC), the team used the prototype to solve the Gaussian boson sampling problem at a speed more than 1054 times that of the world’s most powerful supercomputer, the study said.
The researchers said they manipulated and detected quantum states of up to 3,050 photons —a significant leap from the 255 photons achieved with the previous Jiuzhang 3.0.
Not every query needs a supercomputer. We benchmarked model quantization across OpenClaw’s full task spectrum and developed a router plugin that sends each query exactly where it belongs. Cut costs by ~20%, speed up ~15% without sacrificing capabilities.
A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it. Researchers used the method to simulate extraordinarily complex quantum materials known as quasicrystals, opening the door to powerful new quantum devices and ultra-efficient electronics. The work could help scientists design advanced topological qubits and materials for future quantum computers.
Why does an ant, with a brain smaller than a grain of sand, find the shortest path better than a human engineer?
Richard Feynman didn’t learn about ants from a textbook. He learned by sitting on his bathroom floor with a sugar cube and a stopwatch. What he discovered wasn’t just biology—it was a biological supercomputer solving the \.
Statistics show clear differences in the population’s immune system according to sex: men are more susceptible to infections and cancers, while women have stronger immune responses, which translate, for example, into better responses to vaccines. Even so, with a more reactive immune system, the probability of the body attacking itself also increases, causing 80% of autoimmune disease development to occur in women.
In this context, understanding the aging of the immune system is key since, with age, the composition of immune cells changes and their protective functions deteriorate, causing a greater susceptibility to diseases. However, understanding how sex influences this profound transformation was not possible until now.
A new study by the Barcelona Supercomputing Center—Centro Nacional de Supercomputación (BSC-CNS) published today in Nature Aging demonstrated, for the first time, that immunological aging follows different dynamics between men and women, identifying the cells and genes responsible for the process, and providing a molecular explanation for the differences that previously were only observed globally in the population.
PRESS RELEASE — Groove Quantum today announced it has raised €16 million in combined funding and demonstrated an 18-qubit semiconductor spin-qubit processor, the largest of its kind ever built. The result marks a step beyond small-scale laboratory prototypes toward a quantum processor architecture designed for large-scale integration. The combined funding consists of €10 million in equity and €6 million in grants. The equity seed round is co-led by Innovation Industries, a leading European deep tech fund, and 55 North, the world’s largest pure-play quantum fund, with participation from Verve Ventures and the European Innovation Council Fund. Additional funding is provided by grants from the EIC Accelerator programme and JU Chips Act funding programme further underscores institutional confidence in Groove’s approach.
Groove will use the capital to scale qubit count exponentially and to begin manufacturing its processors at established semiconductor foundries.
Quantum computers create a fundamentally new way of computing. This opens the door to solving complex challenges that would take today’s most powerful supercomputers impractically long to address, like the discovery of new medicines, and the design of advanced materials for renewable energy – challenges that are highly important and have a profoundly positive impact on humanity.
Despite affecting half of the world’s population, menopause has historically been understudied and misunderstood, both in biomedical research and clinical practice. However, with the increase in life expectancy, the number of women in the postmenopausal stage continues to grow and, in 2021, those over 50 already represented 26% of the world’s population, according to the WHO.
Its effects go far beyond the reproductive system and are associated with an increased risk of cardiovascular, metabolic, neurodegenerative, and bone diseases. Nevertheless, few studies analyzed in depth how this process affects the female reproductive system as a whole, beyond the ovaries.
In this context, a new study by the Barcelona Supercomputing Center—Centro Nacional de Supercomputación (BSC-CNS), published in Nature Aging, presents the first large-scale atlas of female reproductive system aging, providing a new vision of how this process impacts health.
The most demanding calculations in quantum chemistry can now be solved with graphics processing unit (GPU) supercomputers. A recently published study shows that software adapted to use GPU hardware can provide not just speed, but also the accuracy needed to solve complex chemistry problems. The work solved the two chemical structures often seen as too complex and expensive to tackle. The advance, published in the Journal of Chemical Theory and Computation, could allow researchers to make meaningful progress in designing new catalysts and improve predicted behaviors of magnetic and electronic materials.
Specifically, the research team—led by computational chemists from NVIDIA, Sandbox AQ, the Wigner Research Centre in Hungary, the Institute for Advanced Study of the Technical University of Munich in Germany, and the Department of Energy’s Pacific Northwest National Laboratory—showed that NVIDIA Blackwell architecture effectively tackles complex simulations. Here, the researchers used a mixture of mathematically precise and approximated approaches to accomplish their goal.
“Our study shows that AI-oriented hardware can do more than provide speed—it can also power chemically accurate, strongly correlated quantum chemistry at the frontier of what is computationally feasible,” said Sotiris Xantheas, a computational chemist at PNNL and study author. Xantheas also serves as the principal investigator of Scalable Predictive methods for Excitations and Correlated phenomena (SPEC), a Department of Energy initiative.

*Description:* Can scientists really simulate a full human brain now? In this video, we explore the latest study claiming that supercomputers may soon be powerful enough to simulate the human brain. We break down how this new method works, why previous brain simulation projects failed, what makes this new research different, and the big ethical questions that come with it. Is this the future of neuroscience and artificial intelligence, or are we still far from creating a true digital human mind? Watch till the end to understand the science in simple words.
