Quantum technologies—and quantum computers in particular—have the potential to shape the development of technology in the future. Scientists believe that quantum computers will help them solve problems that even the fastest supercomputers are unable to handle yet. Large international IT companies and countries like the United States and China have been making significant investments in the development of this technology. But because quantum computers are based on different laws of physics than conventional computers, laptops, and smartphones, they are more susceptible to malfunction.

An interdisciplinary research team led by Professor Jens Eisert, a physicist at Freie Universität Berlin, has now found ways of testing the quality of quantum computers. Their study on the subject was recently published in the scientific journal Nature Communications. These scientific quality control tests incorporate methods from physics, computer science, and mathematics.

Quantum physicist at Freie Universität Berlin and author of the study, Professor Jens Eisert, explains the science behind the research. “Quantum computers work on the basis of quantum mechanical laws of physics, in which or ions are used as computational units—or to put it another way—controlled, minuscule physical systems. What is extraordinary about these computers of the future is that at this level, nature functions extremely and radically differently from our everyday experience of the world and how we know and perceive it.”

The battery can be charged for up to 200 cycles and does not contain wires or toxic heavy metals.

Researchers at the Nanyang Technological University (NTU) in Singapore have devised a micrometer-thin battery that can power smart contact lenses and be charged with tears, a university press release said.

Contact lenses have long been used for vision correction. With technological advancements, companies have been working to make smarter versions, connecting to devices like smartphones and displaying information close to the wearer’s eyes. Such applications require the lenses to have an internal battery.

Many users who want more from their smartphones are glad to use a plethora of advanced features, mainly for health and entertainment. Turns out that these features create a security risk when making or receiving calls.

Researchers from Texas A&M University and four other institutions created malware called EarSpy, which uses machine learning algorithms to filter caller information from ear speaker vibration data recorded by an Android smartphone’s own motion sensors, without overcoming any safeguards or needing user permissions.

Parents who limit their kids’ screen time, it seems, may be doing them a service: a new study has found that babies who spend a lot of time looking at iPads and other screens experience developmental delays.

Published this week in the Journal of the American Medical Association of Pediatrics, this new research out of Japan suggests that watching screens may limit infants’ practicing of real-life motor skills that they glean from mimicking the people near them.

In a questionnaire, the parents of the more than 7,000 kids surveyed were asked a simple question: “On a typical day, how many hours do you allow your children to watch TV, DVDs, video games, internet games (including mobile phones and tablets), etc?”

The company calls it the iPhone of bots as development partners will further applications of this humanoid robot.

Texas-based Apptronik unveiled its first commercial humanoid robot designed to complement the industrial workforce by doing repetitive tasks that humans do not want to do, a press release said. The bot is pocket-friendly and aims to be interaction friendly, making it easier to work alongside humans even in some of the toughest environments, a definite competitor for Tesla’s humanoid bot Optimus.

The use of robotics in industrial workspaces is inevitable, and companies such as Amazon have already deployed them in large numbers to increase the efficiency of their operations. A … More.

It’s notoriously difficult for doctors to identify a wound that is becoming infected. Clinical signs and symptoms are imprecise and methods of identifying bacteria can be time-consuming and inaccessible, so a diagnosis can be subjective and dependent on clinician experience. But infection can stall healing or spread into the body if it isn’t treated quickly, putting a patient’s health in grave danger. An international team of scientists and clinicians thinks they have the solution: a device run from a smartphone or tablet app, which allows advanced imaging of a wound to identify infection.

“Wound care is one of today’s most expensive and overlooked threats to patients and our overall health care system,” said Robert Fraser of Western University and Swift Medical Inc., corresponding author of the study published in Frontiers in Medicine. “Clinicians need better tools and data to best serve their patients who are unnecessarily suffering.”

The scientists developed a device called the Swift Ray 1, which can be attached to a smartphone and connected to the Swift Skin and Wound software. This can take medical-grade photographs, infrared thermography images (which measure body heat), and bacterial fluorescence images (which reveal bacteria using violet light).

The team used acupuncture needles to deliver the trigger for 10 seconds a day, and the blood sugar levels in the mice returned to normal within a month. The rodents even regained the ability to manage blood sugar levels after a large meal without the need for external insulin, a normally difficult feat.

Called “electrogenetics,” these interfaces are still in their infancy. But the team is especially excited for their potential in wearables to directly guide therapeutics for metabolic and potentially other disorders. Because the setup requires very little power, three AA batteries could trigger a daily insulin shot for more than five years, they said.

The study is the latest to connect the body’s analogue controls—gene expression—with digital and programmable software such as smartphone apps. The system is “a leap forward, representing the missing link that will enable wearables to control genes in the not-so-distant future,” said the team.

Metal oxide’s properties could enable a wide range of terahertz frequency photonics.

Visible light is a mere fraction of the electromagnetic spectrum, and the manipulation of light waves at frequencies beyond human vision has enabled such technologies as cell phones and CT scans.

Rice University researchers have a plan for leveraging a previously unused portion of the spectrum.
