So many climate models, so little time ... A new way of measuring ocean temperatures helps scientists sort the likely from unlikely scenarios of global warming.

Researchers develop new tool for analyzing large superconducting circuits

Posted: 13 Sep 2021 10:58 AM PDT

New research tools are needed to fully develop quantum computers and advance the field. Now researchers have developed and tested a theoretical tool for analyzing large superconducting circuits. These circuits use superconducting quantum bits, the smallest units of a quantum computer, to store information. Circuit size is important since protection from detrimental noise tends to come at the cost of increased circuit complexity. Currently there are few tools that tackle the modeling of large circuits.

A universal system for decoding any type of data sent across a network

A new silicon chip can decode any error-correcting code through the use of a novel algorithm known as Guessing Random Additive Noise Decoding (GRAND).

Emissions from computing and ICT could be worse than previously thought

Posted: 10 Sep 2021 09:17 AM PDT

Researchers claim that previous calculations of ICT's share of global greenhouse emissions, estimated at 1.8-2.8%, likely fall short of the sector's real climate impact as they only show a partial picture. The researchers point out that some of these prior estimates do not account for the full life-cycle and supply chain of ICT products and infrastructure -- such as: the energy expended in manufacturing the products and equipment; the carbon cost associated with all of their components and the operational carbon footprint of the companies behind them; the energy consumed when using the equipment; and also their disposal after they have fulfilled their purpose.
