Quanta

[:es]The quest for «quantum supremacy» – unambiguous proof that a quantum computer does something faster than an ordinary computer – has paradoxically led to a boom in quasi-quantum classical algorithms. […]

[:es]Quantum computers should soon be able to beat classical computers at certain basic tasks. But before they’re truly powerful, researchers have to overcome a number of fundamental roadblocks.[:]

[:es]A series of fossil finds suggests that life on Earth started earlier than anyone thought, calling into question a widely held theory of the solar system’s beginnings.[:]

[:es]Compact genomes and tiny cells gave flowering plants an edge over competing flora. This discovery hints at a broader evolutionary principle.[:]

[:es]For decades, physicists have struggled to create a quantum theory of gravity. Now an approach that dates to the 1970s is attracting newfound attention.[:]

[:es]Corina Tarnita deciphers bizarre patterns in the soil created by competing life-forms. She’s found that they can reveal whether an ecosystem is thriving or on the verge of collapse.[:]

[:es]For decades, an origin-of-life story starring RNA has prevailed. New research may be shaking that theory’s hold on our understanding of life’s beginnings.[:]

[:es]Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave.[:]

[:es]Edward Witten reflects on the meaning of dualities in physics and math, emergent space-time, and the pursuit of a complete description of nature.[:]
