For years, quantum computing’s news cycle was dominated by headlines about record-setting systems. Researchers at Google and IBM have had spats over who achieved what—and whether it was worth the effort. But the time for arguing over who’s got the biggest processor seems to have passed: firms are heads-down and preparing for life in the…
Ultrafast computer processing speeds are possible with optical chirality logic gates that operate about a million times faster than existing technologies. Processing devices based on polarized light run one million times faster than current technology. Logic gates are the basic building blocks of computer processors. Conventional logic gates are electronic, working by shuffling around electrons….
In case you had not noticed, computers are hot—literally. A laptop can pump out thigh-baking heat, while data centers consume an estimated 200 terawatt-hours each year—comparable to the energy consumption of some medium-sized countries. The carbon footprint of information and communication technologies as a whole is close to that of fuel use in the aviation…
