New Photonic Chip Spawns Nested Topological Frequency Comb
Scientists on the hunt for compact and robust sources of multicolored laser light have generated the first topological frequency comb. Their result, which relies on a small silicon nitride chip patterned with hundreds of microscopic rings, will appear in the June 21, 2024 issue… Read More - Research News
Attacking Quantum Models with AI: When Can Truncated Neural Networks Deliver Results?
Currently, computing technologies are rapidly evolving and reshaping how we imagine the future. Quantum computing is taking its first toddling steps toward delivering practical results that promise unprecedented abilities. Meanwhile, artificial intelligence remains in public conversation as it’s used for everything from writing business… Read More - Research News
IceCube Observes Seven Astrophysical Tau Neutrino Candidates
Neutrinos are tiny, weakly interacting subatomic particles that can travel astronomical distances undisturbed. As such, they can be traced back to their sources, revealing the mysteries surrounding the cosmos. High-energy neutrinos that originate from the farthest reaches beyond our galaxy are called astrophysical neutrinos… Read More - Research News
A Focused Approach Can Help Untangle Messy Quantum Scrambling Problems
The world is a cluttered, noisy place, and the ability to effectively focus is a valuable skill. For example, at a bustling party, the clatter of cutlery, the conversations, the music, the scratching of your shirt tag and almost everything else must fade into… Read More - Research News
New Laser Experiment Spins Light Like a Merry-go-round
In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light constantly nudges things and can even be used to push spacecraft.… Read More - Research News
The Many Wonders of Uranium Ditelluride
In the menagerie of exotic materials, superconductors boast their own vibrant ecosystem. All superconductors allow electricity to flow without any resistance. It’s their hallmark feature. But in many cases, that’s where the similarities end. Some superconductors, like aluminum, are conventional—run-of-the-mill, bread-and-butter materials that are… Read More - Research News
Simulations of ‘Backwards Time Travel’ Can Improve Scientific Experiments
If gamblers, investors and quantum experimentalists could bend the arrow of time, their advantage would be significantly higher, leading to significantly better outcomes. Adjunct Assistant Professor and JQI affiliate Nicole Yunger Halpern and her colleagues at the University of Cambridge have shown that by… Read More - Research News
Embracing Uncertainty Helps Bring Order to Quantum Chaos
In physics, chaos is something unpredictable. A butterfly flapping its wings somewhere in Guatemala might seem insignificant, but those flits and flutters might be the ultimate cause of a hurricane over the Indian Ocean. The butterfly effect captures what it means for something to… Read More - Research News
Advocating for Quantum Simulation of Extreme Physics
The Big Bang, supernovae, collisions of nuclei at breakneck speeds—our universe is filled with extreme phenomena, both natural and human-made. But the surprising thing is that all of these seemingly distinct processes are governed by the same underlying physics: a combination of quantum mechanics… Read More
