Researchers from Skoltech and the University of Cambridge have shown that polaritons, the quirky particles that may end up running the quantum supercomputers of the future, can form structures behaving like molecules—and these “artificial molecules” can potentially be engineered on demand. The paper outlining these results was published in the journal Physical Review B. …

Light-Based Quantum Computer Exceeds Fastest Classical Supercomputers
An anonymous reader quotes a report from Scientific American: For the first time, a quantum computer made from photons — particles of light — has outperformed even the fastest classical supercomputers. Physicists led by Chao-Yang Lu and Jian-Wei Pan of the University of Science and Technology of China (USTC) in Shanghai performed a technique called Gaussian boson sampling with their quantum…
Amazon Is Laying the Groundwork for Its Own Quantum Computer
Amazon is laying the groundwork for a quantum computer, deepening efforts to harness technology that can crunch in seconds vast amounts of data that take even the most powerful supercomputers hours or days to process. From a report: Amazon has been hiring for a Quantum Hardware Team within its Amazon Web Services Center for Quantum Computing, according to internal job postings…
Cerebras’ Wafer-Size Chip Is 10,000 Times Faster Than a GPU
An anonymous reader quotes a report from VentureBeat: Cerebras Systems and the federal Department of Energy’s National Energy Technology Laboratory today announced that the company’s CS-1 system is more than 10,000 times faster than a graphics processing unit (GPU). On a practical level, this means AI neural networks that previously took months to train can now train in minutes on the…
Researcher sets record for quantum chemistry calculation
A researcher from The Australian National University (ANU) has used one of the most powerful supercomputers in the world to predict the quantum mechanical properties of large molecular systems with an accuracy that surpasses all previous experiments. …
AI Has Cracked a Key Mathematical Puzzle For Understanding Our World
An anonymous reader shares a report: Unless you’re a physicist or an engineer, there really isn’t much reason for you to know about partial differential equations. I know. After years of poring over them in undergrad while studying mechanical engineering, I’ve never used them since in the real world. But partial differential equations, or PDEs, are also kind of magical. They’re…

Nvidia Pledges To Built Britain’s Largest Supercomputer Following $40 Billion Bid For Arm
U.S. chipmaker Nvidia pledged Monday to build a $52 million supercomputer in Cambridge, England, weeks after announcing it intends to buy British rival Arm for $40 billion. CNBC reports: The supercomputer — named “Cambridge-1” and intended for artificial intelligence (AI) research in health care — is being unveiled by Nvidia founder and Chief Executive Jensen Huang at the company’s GTC 2020…
Will New Object Storage Protocol Mean the End For POSIX?
“POSIX has been the standard file system interface for Unix-based systems (which includes Linux) since its launch more than 30 years ago,” writes Enterprise Storage Forum, noting the POSIX-compliant Lustre file system “powers most supercomputers.” Now Slashdot reader storagedude writes: POSIX has scalability and performance limitations that will become increasingly important in data-intensive applications like deep learning, but until now it…
