Diamond’s newfound defect may tame vibrations that hinder quantum light sources

Researchers in the Department of Electrical and Computer Engineering at the University of Illinois Urbana-Champaign have discovered a new type of quantum light emitter in diamonds that could help overcome a number of challenges facing quantum technologies.

First AI-driven telescope goes stargazing

Every night, astronomers must carefully assess changing weather, the intensity of moonlight and shifting atmospheric conditions before deciding where to point a telescope. It’s a constant balancing act designed to squeeze as much science as possible from every precious hour beneath dark skies. Now, Northwestern University, University of Chicago and Fermilab scientists have developed a new artificial intelligence (AI) tool that automatically determines where a telescope should point.

Surprising boiling behavior in liquids could advance future space missions

When astronauts travel deeper into space, every drop of fuel becomes critical, and keeping those fuels stable for months or even years is one of the biggest engineering challenges facing future missions. Now, University of Florida researchers have uncovered a surprising behavior in boiling liquids that could help solve that challenge.

New photonic platform offers a four-lane highway for light

Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this one-way flow has only been found at the boundary between two specially engineered “topological insulator” regions, leaving most of the material unavailable for light transport.

Less-explored form of quantum code could be more powerful—and more stable—than its alternative in error correction

In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn’t matter (3 + 2 is the same as 2 + 3, and it doesn’t matter which sock goes on first). Noncommutative means the order does matter.

Astronomers finally measure the full size of the largest known galaxy

Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy’s outer edge for the first time. The observations confirm it as the largest known galaxy, spanning roughly 520 kiloparsecs, or about 1.7 million light-years, and containing an estimated 3.4 trillion solar masses in stars. The paper was posted to the arXiv preprint server on July 16.

Two independent studies push semiconductor qubits towards practical scales

Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain open: how to connect qubits that aren’t sitting right next to each other, and how to control huge numbers of them without an unmanageable tangle of wiring.

Probing binary stars in the Small Magellanic Cloud with the JWST

The formation and evolution of individual stars in a galaxy shape the evolution of the galaxy itself. Stars and stellar remnants make up the vast majority of a galaxy’s mass, so it’s not surprising that the stellar population affects the evolution of galaxies. In the Milky Way’s disk and bulge, stars and dead stars make up about 85% of the baryonic mass.

Risks of debris between the Earth and the moon for future exploration

Cislunar space has become the focal point of considerable interest and strategic planning because of the many proposed missions to send crews to the moon in the next decade. These include NASA’s Artemis program, China and Russia’s International Lunar Research Station (ILRS), the European Space Agency’s Argonaut program and others. The long-term goals of these programs include creating infrastructure between Earth and the moon that will facilitate continued exploration and even development.

A thermal camera trick could let LIGO see twice as far

There’s a nice kind of irony buried in this story: One of the most sensitive instruments ever built, capable of measuring distortions smaller than the width of a proton, has been quietly held back by something as mundane as heat. And the fix, it turns out, is not some exotic new sensor but a thermal camera you could genuinely buy off the shelf.

Photonic time crystals unlock ultrafast control of light in the terahertz range

An international team of researchers from École Polytechnique, Collège de France and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an all-optical photonic time crystal (PTC), a material whose optical properties can be strongly and periodically modulated over ultrafast timescales.

Quantum spin effects may enhance one-way electrical transport in chiral magnets

Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, but the role of quantum effects in this behavior has remained unclear. Through theoretical analysis, the researchers showed that chiral magnetic systems exhibit logarithmic temperature dependence at low temperatures, offering new insights into electron transport in magnetic materials. These findings are expected to play a crucial role in spintronics.
