Nov 4th, 2025 - Follow Earth on Google A team led by MIT used a simple molecule to peek inside a radium atom's nucleus. In a new study, they watched electrons in radium monofluoride pick up a tiny energy change that betrays what is happening deep in the core. The tests ran on a compact setup at CERN in Switzerland and not in a collider that stretches for miles. The result points to a practical way to map nuclear structure and to probe why the universe favors matter over antimatter. Radium monofluoride reveals ... [Read More]

Nov 3rd, 2025 - Reading time 2 minutes When things don't make sense in the quantum realm, scientists don't always get to find a good explanation for what they're seeing. Many times, they arrive at a solution by accident —something that usually begins with the realization that a weird signal is not a wrong signal. Researchers had known about an odd phenomenon in which an initially conductive material seemingly loses its ability to conduct electricity altogether. Although physicists suspected electrons ...

Oct 22nd, 2025 - The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow the principles of quantum physics, but those principles do not seem to be compatible with the accepted theory of gravity. For years, researchers have been proposing experiments to show whether gravity could produce a phenomenon known as quantum entanglement. Now, two theoretical ... [Read More]

Oct 20th, 2025 - In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, is of considerable interest among physicists and engineers. Research published in reveals a previously hidden feature that could explain how and why enigmatic quantum phases emerge. Using a new terahertz (THz) spectroscopic technique, the researchers revealed that ... [Read More]

Oct 18th, 2025 - The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, with masses of around 100 GeV/c 2 ), primordial black holes, and ultralight axion-like particles (mass of 10 -22 to 1 eV/c 2 ). In the latter case, dark matter behaves like a wave, described by a Schrödinger equation, rather than as a collection of point particles. ... [Read More]

Oct 11th, 2025 - , Phys.org Quantum networks, systems consisting of connected quantum computers, quantum sensors or other quantum devices, hold the potential of enabling faster and safer communications. The establishment of these networks relies on a quantum phenomenon known as entanglement, which entails a link between particles or systems, with the quantum state of one influencing the other even when they are far apart. The atom-based qubits used to establish quantum networks so far operate at visible or ... [Read More]

Oct 10th, 2025 - Follow Earth on Google Quantum computing is full of ideas that sound great until you try to build them. A new experiment now shows a way to move quantum data to exactly where it is needed. It reports 95.3 % success on that routing task in the lab, which is strong enough to take notice. Instead of treating memory as an afterthought, the team built a router that can direct a quantum signal based on a quantum address. That ability is central to designs for quantum random access memory ( QRAM ). It ... [Read More]

Oct 10th, 2025 - A research team led by Prof. Lin Yiheng from the University of Science and Technology of China (USTC), collaborating with Prof. Yuan Haidong from the Chinese University of Hong Kong, succeeded in generating multipartite quantum entangled states across two, three, and five modes using controlled dissipation as a resource. Their study is in Science Advances . Multimode entanglement is a key resource in quantum computation, communication, simulation, and sensing. One of the major challenges in ... [Read More]

Oct 8th, 2025 - Reseachers uses quantum simulations to vizualize the shape of a photon emitted by a single nanoparticle -- in this case, it's lemon-shaped. When we look at the world around us, all that we see is thanks to light. It reflects, refracts, and interacts, carrying shape and depth from the objects it touches. But what about light itself? Physicists have now visualized the simulated shape of a photon (the smallest unit of light) emitted from the surface of a nanoparticle using a novel theoretical ... [Read More]

Oct 3rd, 2025 - Engineers have developed a new coating technique that will help make quantum light sources more precise and consistent. The team used an organic molecule called PTCDA to coat a semiconductor and caused it to release single photons at a time. Each photon also had identical energies, which is required if quantum technologies are to function. The researchers hope these reliable semiconductors will improve the performance of quantum computers. "The big idea is that we want to go from individual ... [Read More]

Oct 3rd, 2025 - By Florian Neukart, Leiden University Share What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred years, physics has rested on two foundational theories. Einstein's general relativity describes gravity as the curvature of space and time, while quantum mechanics governs the behavior of particles and fields. Each theory is highly successful within its own domain, yet combining them leads to contradictions, particularly in ... [Read More]

Oct 2nd, 2025 - Follow Earth on Google A single particle of light can behave in surprising ways, but it still follows the strict rules of physics. A new experiment shows that even when one photon is split into two, the total angular momentum remains exactly the same. The work tested conservation at the smallest possible scale and did not cut corners. Lead author Lea Kopf of Tampere University , and colleagues built a setup sensitive enough to catch only a few successful events out of billions. Split photons ... [Read More]

Oct 1st, 2025 - A laser-controlled array of atoms may hold the key to scalable quantum computing In a Caltech lab, a computer screen showed thousands of tiny points of light—each one a single atom, held in place by laser beams. This striking image revealed 6,100 stable quantum bits, or qubits. It's the largest neutral-atom array ever created and a key achievement for quantum computing. The previous record for a neutral atom array was just 1,180 qubits. "This is an exciting moment for neutral-atom quantum ... [Read More]

Sep 29th, 2025 - , Phys.org Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same properties over time, these materials break so-called temporal translation symmetry. This in turn prompts the emergence of various fascinating phenomena, including time reflection, refraction and diffraction. Most time-varying materials studies so far are optical systems , or in other ... [Read More]
