Upcoming telescopes could shed light on dark matter

NASA’s plans to return astronauts to the moon through the Artemis program and ultimately send humans to Mars highlight just how far space exploration has come. Yet while the moon and Mars remain compelling destinations filled with scientific mysteries, looking beyond our solar system raises even deeper questions about the universe itself.

Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy

Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have developed a practical, comprehensive noise-modeling framework for a popular class of superconducting quantum processors. Their work, published in the journal PRX Quantum, offers a sevenfold improvement in predictive accuracy over existing approaches.

What happens to a star that captures a primordial black hole?

We don’t know whether theorized primordial black holes (PBH) are real. If they are, they formed in the very early universe, when physics was much different. They had no stellar progenitors and were created by the direct collapse of densely packed subatomic matter. Theorists have wondered whether PBH could be dark matter, or a component […]

Why this $10 spectrometer chip could bring real-time chemical sensing to wearables

Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers laboratory-grade precision in a device small enough to be embedded in portable and wearable technologies. By rethinking how spectra are measured and processed, the team has demonstrated a […]

New cryogenic silicon carbide hardware addresses quantum computing bottleneck

Researchers from the Department of Electrical and Computer Engineering in the Faculty of Engineering at the University of Hong Kong (HKU) and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC) have achieved a major breakthrough in cryogenic electronics. The team has developed a programmable neuromorphic hardware platform that operates near absolute zero, providing a […]

Plants could be used to grow medicines in space, study shows

Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to grow and repeatedly harvest pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large […]

Neutron star merger simulations gain new precision with AI-driven r-process heating

Using a novel simulation model based on machine learning, an international research team at GSI/FAIR has succeeded in gaining a deeper understanding of element formation in stellar events such as neutron star mergers. For the first time, the scientists used deep learning with a neural network to model the energy release during r-process nucleosynthesis in […]

Research uncovers novel electronic properties in quantum material

Florida State University physicists are part of a team that has discovered unusual superconducting states in parts of graphene, with the potential to drive unexpected quantum technologies.

Physicists create new family of Schrödinger-cat states

Quantum mechanics, unlike classical physics, allows objects to exist in more than one state at the same time. This idea is often illustrated by Schrödinger’s cat, imagined as being both alive and dead until it is observed. In the laboratory, physicists can create less dramatic but very real versions of this effect by placing atoms, […]

Tabletop experiment helps reconcile fundamental physics

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two bedrock physics theories that have never been fully reconciled.

Newfound sound wave scattering rule may lead to less bulky, more effective soundproofing

Researchers in China recently uncovered a quantum-inspired rule governing how sound is scattered by certain physical properties of a material. Their research, published in Physical Review Letters, may lead to the ability to design materials with optimal, broadband sound blocking.

Achiral crystal reveals Raman optical activity through ferroaxial order

Raman optical activity, long thought to require chiral molecules or magnetic order, has been demonstrated in an achiral, nonmagnetic crystal by researchers at the Institute of Science Tokyo. The effect arises through ferroaxial order, a coordinated rotation of atoms within the lattice, and is detected using circularly polarized Raman spectroscopy. The findings show that optically […]
