Novel theorem demonstrates convolutional neural networks can always be trained on quantum computers, overcoming threat of ‘barren plateaus’ in optimization problems. Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can. While a fundamental solvability problem known as “barren plateaus” has limited the application of these neural networks for large data sets, new research overcomes that Achilles heel with a rigorous proof that guarantees scalability.

New results on nucleon structure. Two independent studies have illuminated unexpected substructures in the fundamental components of all matter. Preliminary results using a novel tagging method could explain the origin of the longstanding nuclear paradox known as the EMC effect. Meanwhile, authors will share next steps after the recent observation of asymmetrical antimatter in the proton.

Both groups will discuss their experiments at DOE’s Thomas Jefferson National Accelerator Facility and Fermilab during the 2021 Fall Meeting of the APS Division of Nuclear Physics.

One study presents new evidence on the EMC effect, identified nearly 40 years ago when researchers at CERN discovered something surprising: Protons and neu...

The University of Surrey has developed a new, cost-effective, ecological solution for augmenting the printed page with rich, uptodate digital content. The development overcomes one of the most significant advantages e-books have over paper books, helping paper maintain its strong position in its competition with electronic media.

Researchers at the University of Surrey’s Advanced Technology Institute and Digital World Research Centre have designed an elegant and intuitive electronic system that allows the readers of a paper book to access related multimedia content by simply placing a bookmark on a page. The Magic Bookmark uses optical contrast sensors to discern a pattern printed next to the book’s spine on each page...
