Researchers fabricate chip-based optical resonators with record low UV losses

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

Researchers have created chip-based photonic resonators that operate in the ultraviolet (UV) and visible regions of the spectrum and exhibit a record low UV light loss. The new resonators lay the groundwork for increasing the size, complexity and fidelity of UV photonic integrated circuit (PIC) design, which could enable new miniature chip-based devices for applications such as spectroscopic sensing, underwater communication and quantum information processing.

“Compared to the better-established fields like telecom photonics and visible photonics, UV photonics is less explored even though UV wavelengths are needed to access certain atomic transitions in atom/ion-based quantum computing and to excite certain fluorescent molecules for biochemical sensing,” said research team member Chengxing He from Yale University. “Our work sets a good basis toward building photonic circuits that operate at UV wavelengths.”

In Optics Express, the researchers describe the alumina-based optical microresonators and how they achieved an unprecedented low loss at UV wavelengths by combining the right material with optimized design and fabrication.

New spin-squeezing techniques let atoms work together for better quantum measurements

Posted by in categories: particle physics, quantum physics

Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. In the process they have devised ways to measure large groups of atoms more accurately even in disruptive, noisy environments.

The new techniques are described in a pair of papers published in Nature. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.

“Entanglement is the holy grail of measurement science,” said Ana Maria Rey, a and a JILA and NIST Fellow. “Atoms are the best sensors ever. They’re universal. The problem is that they’re quantum objects, so they’re intrinsically noisy. When you measure them, sometimes they’re in one , sometimes they’re in another state. When you entangle them, you can manage to cancel the noise.”

Can you melt eggs? Quora’s AI says “yes,” and Google is sharing the result

Posted by in category: robotics/AI

When you type a question into Google Search, the site sometimes provides a quick answer called a Featured Snippet at the top of the results, pulled from websites it has indexed. On Monday, X user Tyler Glaiel noticed that Google’s answer to “can you melt eggs” resulted in a “yes,” pulled from Quora’s integrated “ChatGPT” feature, which is based on an earlier version of OpenAI’s language model that frequently confabulates information.

“This is actually hilarious,” Glaiel wrote in a follow-up post. “Quora SEO’d themselves to the top of every search result, and is now serving chatGPT answers on their page, so that’s propagating to the answers google gives.” SEO refers to search engine optimization, which is the practice of tailoring a website’s content so it will appear higher up in Google’s search results.

Q&A: ‘Crystal ribcage’ technology pioneers new approaches to lung health

Posted by in categories: biotech/medical, health

It’s no secret that our lungs play a vital role in our daily lives—ensuring we can breathe, fend off infections, and adapt to various challenges. Despite their importance, the organs still puzzle many medical experts, especially when they’re affected by diseases. While traditional tools like MRI and CT scans are helpful when a patient is experiencing a lung-related illness, they can still fall short in providing the detailed, real-time information needed to understand the intricacies of lung health.

Enter the groundbreaking innovation known as the crystal ribcage. Developed by researchers in Boston University’s College of Engineering, Pulmonary Center, Center for Multiscale and Translational Mechanobiology, and Neurophtonics Center, the technology is poised to revolutionize not only our understanding of lung function but also holds immense potential for other organs and treatments.
