A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman effects within one microresonator, the microcomb has a spectral width exceeding 300 nm and a repetition rate of 26.03 GHz, without the need for external electronic feedback. Go to […] In a study published in Reports on Progress in Physics, researchers have achieved device-independent characterization of genuinely entangled subspaces (GESs) in both optical and superconducting quantum systems, completing the self-checking of the five-qubit error correction code space. Go to Source Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be. Go to Source The quantum many body problem has been at the heart of much of theoretical and experimental physics over the past few decades. Even though we have understood the fundamental laws that govern the behavior of elementary particles for almost a century, the issue is that many interesting phenomena are the result of the complex collective […] The field of ultrafast magnetism explores how flashes of light can manipulate a material’s magnetization in trillionths of a second. In the process called all-optical switching (AOS), a single laser pulse of several femtoseconds (≈10-15 seconds) duration flips tiny magnetic regions without the need for an externally applied magnetic field. Go to Source […] Forensic analysis is still in its early stages, but agents believe nation-state actors used the system to send encrypted messages to organized crime groups, cartels and terrorist organizations Go to Source “[Your] lack of training blows my mind…I’m telling you how you’re supposed to do your job because you obviously don’t know,” the now-former Smithfield council member said Go to Source The pursuit ended when the boy crashed into a Sacramento County Sheriff’s cruiser and a bystander vehicle Go to Source The man had entered a privately owned recreation center with a bloodied bandage; he later became combative and approached Humboldt County Sheriff’s deputies with a knife Go to Source While many are unaware of this, there is a Pyramid (now in ruins) in Greece referred to as the ‘Pyramid of Hellinikon ‘ which according to studies is older than the oldest Pyramid of ancient Egypt by at least 100 years (Djoser – 2620 B.C.) and predates by at least 170 years, the Great […] Nature has many rhythms: the seasons result from Earth’s movement around the sun, the ticking of a pendulum clock results from the oscillation of its pendulum. These phenomena can be understood with very simple equations. However, regular rhythms can also arise in a completely different way—by themselves, without an external clock, through the complex interaction […] In an article published in Communications Physics, researchers from the Université libre de Bruxelles and the Institute for Quantum Optics and Quantum Information in Vienna present a new framework for describing physics relative to quantum reference frames, unveiling the importance of previously unrecognized “extra particles.” Go to Source The artificial intelligence models that turn text into images are also useful for generating new materials. Over the last few years, generative materials models from companies like Google, Microsoft, and Meta have drawn on their training data to help researchers design tens of millions of new materials. Go to Source Integration into a quantum money protocol shows that memories can now handle very demanding applications for quantum networking. Go to Source The neutral atom array architecture for quantum computing has been rapidly advancing over the last several years, and a recent study published in Nature has just revealed another step forward for this technology. The team of Harvard researchers involved in this study have engineered a 3,000-qubit neutral atom array system capable of operating continuously for […] |
