Scite or leave a comment on SciRate.AbstractWe construct a lower bound of the tensor rank for a new class of tensors, which we call $textit{persistent tensors}$. We present three specific families of persistent tensors, of which the lower bound is tight. We show that there is a chain of degenerations between these three families of minimal-rank persistent tensors that can be used to

Darkness and light: dark solitons have been created in an electrically-injected laser. (Courtesy: iStock/agsandrew) Dark solitons – regions of optical extinction against bright backgrounds – have been seen spontaneously forming in ring semiconductor lasers. Made by an international team of researchers, the observation could lead to improvements in molecular spectroscopy and integrated optoelectronics. Frequency combs – pulsed lasers that output light with equally-spaced frequencies – are one of the most important achievements in the history of laser physics. Sometimes referred to as optical rulers, they are the basis of time

The frequency of the MOT lasers is controlled by a reinforcement learning agent. (Courtesy: Malte Reinschmidt) Cold atoms solve many problems in quantum technology. Want a quantum computer? You can make one from an array of ultracold atoms. Need a quantum repeater for a secure communications network? Cold atoms have you covered. How about a quantum simulator for complicated condensed-matter problems? Yep, cold atoms can do that, too. The downside is that doing any

China has given itself a goal to become a world-leading source of AI infrastructure by 2027, the country's Ministry of Industry and Information Technology (MIIT) announced in a policy document released on Monday. The document lists facilities and technologies that Beijing has declared important to a technologically advanced future economy – including an "ultra-large-scale new intelligent computing center" that can handle iterative training of large models. To make this "innovative iconic" product happen, Beijing said it must accelerate breakthroughs in GPUs, clustered low-latency interconnection networks, and heterogeneous resource management tech
