A Stony Brook University research team has uncovered a novel regime, or set of conditions within a system, for cooperative radiative phenomena, casting new light on a 70-year-old problem in quantum optics.
The FAU College of Engineering and Computer Science recently welcomed Arslan Munir, Ph.D., an internationally renowned expert, researcher and pioneer in advanced computing and smart technologies who has made numerous contributions to the fields of artificial intelligence, cybersecurity and intelligent systems.
Dr. Hyang-Tag Lim's research team at the KIST has implemented a quantum computing algorithm that can estimate interatomic bond distances and ground state energies with chemical accuracy using fewer resources than conventional methods, and has succeeded in performing accurate calculations without the need for additional quantum error mitigation techniques.
Entangled quantum bits per second (ebps) indicates a quantum network鈥檚 throughput. In this study, researchers collected ebps measurements over a suite of fiber connections on a quantum network testbed. They then compared these measurements with capacity estimates for a conventional fiber-optic network at a range of distances. The study finds that ebps throughput decays sharply with distance in ways that differ from conventional networks.

Electronics and Telecommunications Research Institute (ETRI) announced that they have developed a system capable of controlling eight photons using a photonic integrated-circuit chip. With this system, they can explore various quantum phenomena, such as multipartite entanglement resulting from the interaction of the photons.
How to keep stray radiation from 鈥渟horting鈥� superconducting qubits; a pair of studies shows where ionizing radiation is lurking and how to banish it.
So-called 鈥淴YZ states鈥� defy the standard picture of particle behavior and have given rise to several attempts to understand their nature.
Much of modern life depends on the coding of information onto means of delivering it. Researchers at Aalto University鈥檚 Department of Applied Physics found a new way to create tiny hurricanes of light 鈥� known to scientists as vortices 鈥� that can carry large amounts of information via cable.
Researchers have taken direct images of the Wigner molecular crystal, a new quantum phase of an electron solid. The breakthrough may advance future technologies for quantum simulations.
New 2024 American Physical Society Fellow Jozef Dudek is pursuing theoretical descriptions of exotic hadrons, a yet-untallied group of short-lived subatomic cousins of the proton and neutron, those more familiar atomic building blocks.
Nuclear physics theorists have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made of a quark and an antiquark. The calculations also help validate a method that will be used to make predictions for and analyze data from high-energy experiments at the future Electron-Ion Collider (EIC) at Brookhaven National Laboratory.
Science can be difficult to explain to the public. Explaining a theoretical science concept to high school students requires a new way of thinking altogether, which is precisely what researchers at UC San Diego did when they orchestrated a dance with high school students at Orange Glen High School in Escondido as a way to explain topological insulators. The experiment was led by former graduate student Matthew Du and UC San Diego Associate Professor of Chemistry and Biochemistry Joel Yuen-Zhou.
Engineering professor Mingzhe Chen is working on several projects that could improve on our existing wireless networks. For this work, he was recently named as the Knight Foundation chair in data science and artificial intelligence.
Quantum technologies promise breakthroughs in communication, computing, sensors and much more. However, quantum states are fragile, and their effects are difficult to grasp, making research into real-world applications challenging. Empa researchers and their partners have now achieved a breakthrough: Using a kind of 鈥渜uantum Lego鈥�, they have been able to accurately realize a well-known theoretical quantum physics model in a synthetic material.
To run on a quantum computer, algorithms must be decomposed into a sequence of quantum gates, a difficult process. In this study, researchers developed a novel 鈥渉ybrid鈥� approach to quantum hardware design that replaces part of the quantum circuit with a physical evolution that relies on natural interactions within the system. This approach significantly reduces the complexity of executing quantum algorithms.
Science isn鈥檛 scary, but it can be spooky! For Halloween, we鈥檙e highlighting some 鈥渟pooky鈥� research that the Department of Energy鈥檚 (DOE) Office of Science supports. In fact, the physics community celebrates Dark Matter Day on Halloween! We hope that this roundup puts you in the mood to dig a little deeper into the wonders that surround you.
A recent collaboration among researchers from HUN-REN Wigner Research Centre for Physics in Hungary and the Department of Energy鈥檚 Pacific Northwest National Laboratory, along with industry collaborators SandboxAQ聽and NVIDIA, has achieved unprecedented speed and performance in聽efforts to model complex metal-containing molecules.
