Dartmouth and MIT research advances noise cancelling for quantum computers

A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, “non-Gaussian” noise processes that are routinely encountered in superconducting quantum computing systems. The characterization of non-Gaussian noise in superconducting quantum bits is a critical step toward making these systems more precise. … Read more

Light and sound in silicon chips: The slower the better

Integrated circuits in silicon enable our digital era. The capabilities of electronic circuits have been extended even further with the introduction of photonics: components for the generation, guiding and detection of light. Together, electronics and photonics support entire systems for data communication and processing, all on a chip. However, there are certain things that even … Read more

‘How We Respond’ spotlights how US communities are addressing climate change impacts

Communities across the United States are working with scientists to respond to climate change impacts, shows a new report and multimedia resources developed by the American Association for the Advancement of Science (AAAS). How We Respond shares details and perspectives from 18 communities using scientific information to adapt to climate change impacts and/or reduce greenhouse gas emissions. … Read more

Early exposure key to recognising ‘other-race’ faces

New research led by The Australian National University (ANU) has shown exposure to people from other racial backgrounds during childhood could help us better recognise faces across different races as adults. The study, led by Professor Elinor McKone, examined the ‘other-race effect’, a phenomenon in which people have difficulty telling apart individuals of a different … Read more

Paramagnetic spins take electrons for a ride, produce electricity from heat

An international team of researchers has observed that local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material – where spins weren’t thought to correlate long enough to do so. This effect, which the researchers call “paramagnon drag thermopower,” converts a temperature difference into an electrical voltage. … Read more

Team discovers polymorph selection during crystal growth can be thermodynamically driven

Technology is getting smaller – which is good news. The ability to fabricate materials with optical, electrical and mechanical properties out of very small particles could have far-reaching applications. For example, micro-particles grafted with DNA can be used in medicine for better sensing, imaging and treatment delivery. An improved understanding of how these materials behave … Read more

‘Soft tactile logic’ tech distributes decision-making throughout stretchable material

Inspired by octopuses, researchers have developed a structure that senses, computes and responds without any centralized processing – creating a device that is not quite a robot and not quite a computer, but has characteristics of both. The new technology holds promise for use in a variety of applications, from soft robotics to prosthetic devices. … Read more
