A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an earthquake, travel across the chip at frequencies nearly a billion times higher than those found in earth tremors.

In a groundbreaking study, researchers from Purdue University and the Max-Planck Institute for Quantum Optics in Munich have revealed an unexpected twist in molecular physics: they can break molecules apart using laser light, only to reform them in a new, stable state. This discovery defies conventional chemistry, where severing chemical bonds typically results in the destruction of the molecule.

A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and the Max Planck Institute for Medical Research in Heidelberg has succeeded in measuring distances within biomolecules using a light microscope, down to one nanometer and with Ångström precision. The intra-molecular resolution achieved with MINFLUX microscopy makes it possible to optically record the spatial distances between subunits in macromolecules and thus to detect different conformations of individual proteins in the light microscope.

Dr. Habib Rostami, from the Department of Physics at the University of Bath, has co-authored pioneering research published in Advanced Science. This study involved an international collaboration between an experimental team at Friedrich Schiller University Jena in Germany and theoretical teams at the University of Pisa in Italy and the University of Bath in the UK. The research aimed to investigate the ultrafast opto-electronic and thermal tuning of nonlinear optics in graphene.

The strength of a coupling between nuclear spins depends on chirality, or handedness, of the molecule, according to a new study by researchers at UCLA, Arizona State University, Penn State, MIT and Technische Universität Dresden. The study also revealed that in chiral molecules of a given handedness – whether it is a left- or right-handed molecule – the nuclear spin tends to align in one specific direction. In molecules with the opposite chirality, such as right-handedness, the spin aligns in the opposite direction.

SoftIron, the worldwide leader in true private cloud infrastructure, today announced the Q4 2024 releases of HyperCloud and VM Squared, introducing critical updates that position them as the world’s first post-quantum safe virtualization and private cloud solutions. These updates deliver advanced security against evolving threats, flexibility in IT asset integration, and enhanced management through an upgraded user interface.

A recent collaboration between the University of Illinois and the University of Chicago addresses this problem by using the using the environment as a help, instead of a hindrance. In using the environment of superconducting qubits, sometimes referred to as a reservoir, the researchers show that more stable entanglement can be created.

Researchers from Saarland University (UdS) have achieved an important breakthrough in Quantum Communication by demonstrating Quantum Entanglement and Teleportation over a 14 km long fiber link, the “Saarbrücken Quantum Communication Fiber Testbed”.

In the CiRQus project, we have implemented laser-controlled interactions between a highly-excited circular Rydberg qubit and a second ionic core electron. This achievement advances control of circular Rydberg atoms from the microwave to the optical domain by combining established tools for manipulating trapped ions with neutral atom arrays.

Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more energy-efficiently than conventional semiconductor devices. However, it is still difficult to create and manipulate spin textures in materials.
