Encoded

Ocean bays that pinch West Antarctica are home to two distinct populations of Turquet's octopus (Pareledone turqueti). The shared secrets of their ancestors do not bode well for the future health of our planet.A new DNA analysis of the two geographically separated octopus populations indicates they were once part of one big family.This direct historical connection suggests that around 125,000 years ago, the massive 2.2 million cubic kilometer (530,000 cubic mile) West Antarctic Ice Sheet (WAIS) that separates the two…

Credit: HRL LaboratoriesHRL Laboratories, LLC, has published the first demonstration of universal control of encoded spin qubits. This newly emerging approach to quantum computation uses a novel silicon-based qubit device architecture, fabricated in HRL’s Malibu cleanroom, to trap single electrons in quantum dots. Spins of three such single electrons host energy-degenerate qubit states, which are controlled by…
