New optical system designed to target and control individual atoms. Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing future functional quantum computers.

This new method, developed at the University of Waterloo’s Institute for Quantum Computing (IQC), uses a small glass waveguide to separate laser beams and focus them four microns apart, about four-hundredths of the width of a single human hair. The precision and extent to which each focused laser beam on its target qubit can be controlled in parallel is unmatched by previous research.

“Our design limits the amount of crosstalk-the amount of light ...

Research at Hokkaido University has revealed that elusive particles called neutrinos can interact with photons, the fundamental particles of light and other electromagnetic radiation, in ways not previously detected. The findings from Kenzo Ishikawa, Professor Emeritus at Hokkaido University, with colleague Yutaka Tobita, lecturer at Hokkaido University of Science, were published in the journal Physics Open.

“Our results are important for understanding the quantum mechanical interactions of some of the most fundamental particles of matter,” says Ishikawa. “They may also help reveal details of currently poorly understood phenomena in the sun and other stars.”

Neutrinos are one of the most mysterious fundamental...

Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation — where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.

Until now, dedifferentiation has primarily been associated with severe injuries or stressful conditions, observed during tissue regeneration and diseases like tumorigenesis...

In a breakthrough for the field of bioelectronics, researchers at EPFL have enhanced the ability of E. coli bacteria to generate electricity. The innovative approach offers a sustainable solution for organic waste processing while outperforming previous state-of-the-art technologies, opening new horizons for versatile microbial electricity production.

“We engineered E. coli bacteria, the most widely studied microbe, to generate electricity,” says Professor Ardemis Boghossian at EPFL. “Though there are exotic microbes that naturally produce electricity, they can only do so in the presence of specific chemicals. E...
