Physicists confirm quantum entanglement persists between top quarks, the heaviest known fundamental particles
An experiment by a group of physicists led by University of Rochester physics professor Regina Demina has produced a significant result related to quantum entanglement—an effect that Albert Einstein called "spooky action at a distance.".....»»
Preparing for a post-quantum future
Post-quantum cryptography (PQC) is a hot topic. A recent paper from Tsinghua University raised doubts about lattice-based cryptography for PQC, though an error was found. This has sparked questions about the strength of soon-to-be-standardized PQC al.....»»

When quantum dots meet blue phase liquid crystal elastomers
Circularly polarized luminescence (CPL) materials have attracted tremendous attention for their potential applications in many fields, such as molecular sensors, information encryption, and optical storage. So far, using cholesteric liquid crystals (.....»»
Quantum entangled photons react to Earth"s spin
A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work, published in Science Advances, represents a si.....»»
Physicists report optical analog of Kármán vortex street
In a study published in Nature Communications, collaborating physicists from Singapore and the UK have reported an optical analog of the Kármán vortex street (KVS). This optical KVS pulse reveals fascinating parallels between fluid transport and en.....»»
Advances in techniques used to identify sharks and rays is not preventing trade and increase in extinction risk: Study
The most advanced molecular techniques contribute significantly to the identification of endangered sharks, rays and skates, collectively known as elasmobranchs, and are therefore fundamental to the enforcement of the laws and regulations governing t.....»»
Liquid crystal source of photon pairs opens path to new generation of quantum sources
Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids......»»
A route to scalable Majorana qubits
Researchers at QuTech have found a way to make Majorana particles in a two-dimensional plane. This was achieved by creating devices that exploit the combined material properties of superconductors and semiconductors. The inherent flexibility of this.....»»
Satellite "megaconstellations" may jeopardize recovery of ozone hole
When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth's protective ozone layer. A new study finds that these oxides have increased 8-fold between 2016 and 2022 and wi.....»»
20,000 FortiGate appliances compromised by Chinese hackers
Coathanger – a piece of malware specifically built to persist on Fortinet’s FortiGate appliances – may still be lurking on too many devices deployed worldwide. How Coathanger persists on FortiGate devices In February 2024, the Dutch Mil.....»»
New theory links quantum geometry to electron-phonon coupling
A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions......»»
New technique could help build quantum computers of the future
Quantum computers have the potential to solve complex problems in human health, drug discovery, and artificial intelligence millions of times faster than some of the world's fastest supercomputers. A network of quantum computers could advance these d.....»»
Pseudomagic quantum states: A path to quantum supremacy
A new study in Physical Review Letters (PRL) introduces the concept of pseudomagic quantum states, which appear to have high stabilizerness (or complexity) and can move us closer to achieving quantum supremacy......»»
Thermoelectric effect between two liquid materials observed for the first time
A trio of physicists at Sorbonne Université, in France, has observed a thermoelectric effect between two liquid materials for the first time. In their study, published in Proceedings of the National Academy of Sciences, Marlone Vernet, Stephan Fauve.....»»
Chemists discover spontaneous nanoparticle formation in charged microdroplets
A team of chemists at the Indian Institute of Technology Madras, working with a pair of colleagues from the Jawaharlal Nehru Center for Advanced Scientific Research, both in India, has found that particles of minerals sometimes break down spontaneous.....»»
How did a satellite galaxy of the Milky Way come to be? Physicists offer an explanation
Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear......»»
Neutrinos: The inscrutable “ghost particles” driving scientists crazy

Investigating collective motions in schools of zebrafish could deepen understanding of active systems
Active systems display a wide range of complex and fascinating behaviors, many of which are not yet fully understood. Found on scales ranging from microbes and self-propelling particles to large groups of fish, birds, and mammals, they are made up of.....»»
Elon Musk"s latest anti-Apple tirade is about a ChatGPT feature that doesn"t exist
Elon Musk has a fundamental misunderstanding of Apple's partnership with ChatGPT and believes that it's the gateway to automatically sharing all user data on iPhone with OpenAI.Apple and OpenAI partnered to bring ChatGPT to SiriOpenAI is one of sever.....»»
"Quantum optical antennas" provide more powerful measurements on the atomic level
Similar to how a radio antenna plucks a broadcast from the air and concentrates the energy into a song, individual atoms can collect and concentrate the energy of light into a strong, localized signal that researchers can use to study the fundamental.....»»
