Skyrocketing AEC data pushes need for data governance best practices

Posted by in categories: computing, engineering, governance

As the architecture, engineering and construction (AEC) industry is undergoing a staggering growth in the creation of data, organizations need to place a strong focus on data governance best practices.

That is one of the findings of a new study of the AEC sector that reveals it has experienced a 31.2% compound growth rate in data storage since 2017. The amount of new data being captured or created is staggering, but getting full value from it depends on how the data is managed, stored, accessed and protected.

Entangled photons tailor-made

Posted by in categories: computing, particle physics, quantum physics

This will be very useful in progressing the field of quantum computers and communication.

Researchers at the Max Planck Institute of Quantum Optics set a new record after achieving a quantum entanglement of 14 photons, the largest on record so far, an institutional press release said.

Quantum entanglement, famously described by Albery Einstein as “spooky action at a distance” is a phenomenon where particles become intertwined in such a way that they cease to exist individually, and changing the specific property of one results in an instant change of its partner, even if it is far away.

Reversing cause and effect is no trouble for quantum computers

Posted by in categories: computing, quantum physics

Watch a movie backwards and you’ll likely get confused—but a quantum computer wouldn’t. That’s the conclusion of researcher Mile Gu at the Centre for Quantum Technologies (CQT) at the National University of Singapore and Nanyang Technological University and collaborators.

In research published 18 July in Physical Review X, the international team shows that a computer is less in thrall to the arrow of time than a classical computer. In some cases, it’s as if the quantum computer doesn’t need to distinguish between cause and effect at all.

The new work is inspired by an influential discovery made almost 10 years ago by complexity scientists James Crutchfield and John Mahoney at the University of California, Davis. They showed that many statistical data sequences will have a built-in arrow of time. An observer who sees the data played from beginning to end, like the frames of a movie, can model what comes next using only a modest amount of memory about what occurred before. An observer who tries to model the system in reverse has a much harder task—potentially needing to track orders of magnitude more information.

New encryption tool is designed to thwart quantum computers

Posted by in categories: computing, encryption, finance, mathematics, quantum physics

An encryption tool co-created by a University of Cincinnati math professor will soon safeguard the telecommunications, online retail and banking and other digital systems we use every day.

The National Institute of Standards and Technology chose four new encryption tools designed to thwart the next generation of hackers or thieves. One of them, called CRYSTALS-Kyber, is co-created by UC College of Arts and Sciences math professor Jintai Ding.

“It’s not just for today but for tomorrow,” Ding said. “This is information that you don’t want people to know even 30 or 50 years from now.”

Remote heart rate sensors can be biased against darker skin. UCLA team offers solution

Posted by in categories: biotech/medical, computing

As telemedicine has grown more popular, so have devices that allow people to measure their vital signs from home and transmit the results by computer to their doctors. Yet in many cases, obtaining accurate remote readings for people of color has proved a persistent challenge.

Take remote heart rate measurements, for example, which rely on a camera sensing subtle changes in the color of a patient’s face caused by fluctuations in the flow of blood beneath their skin. These devices, part of an emerging class of remote technologies, consistently have trouble reading color changes in people with darker skin tones, said Achuta Kadambi, an assistant professor of electrical and computer engineering at the UCLA Samueli School of Engineering.

Kadambi and his team have now developed a remote diagnostic technique that overcomes this against darker skin while also making heart rate readings more accurate for patients across the full range of skin tones. Their secret? Combining the light-based measurements of a camera with radio-based measurements from radar.
