Were Bohr and von Neumann really in conflict over quantum measurements?
Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar views than previously thought regarding the nature of quantum systems, and the classical apparatus used to measure them......»»
Scientists create ultracompact polarization-entangled photon sources for miniaturized quantum devices
Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and hi.....»»
A world mired in conflict calls for international tribunals that play multiple roles
The International Court of Justice in The Hague has been busier than ever in recent years: it has been asked to render judgments and issue advisory opinions on conflicts in Gaza, Ukraine and Myanmar, among others, and it settles border disputes all o.....»»
Sound drives "quantum jumps" between electron orbits
Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be.....»»
Study proposes generalized approach to light-matter interactions
A study coordinated by the University of Trento with the University of Chicago proposes a generalized approach to the interactions between electrons and light. In the future, it may contribute to the development of quantum technologies as well as to.....»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
The Quantum Mechanics of the Greenhouse Effect
Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model......»»
Test of a prototype quantum internet runs under New York City for half a month
To introduce quantum networks into the marketplace, engineers must overcome the fragility of entangled states in a fiber cable and ensure the efficiency of signal delivery. Now, scientists at Qunnect Inc. in Brooklyn, New York, have taken a large ste.....»»
Researcher explores how you can stretch your mind to grasp quantum entanglement
My new article, "Quantum Entanglement of Optical Photons: The First Experiment, 1964–67," is intended to convey the spirit of a small research project that reaches into uncharted territory. The article breaks with tradition, as it offers a first-pe.....»»
Langbeinites show talents as 3D quantum spin liquids
A 3D quantum spin liquid has been discovered in the vicinity of a member of the langbeinite family. The material's specific crystalline structure and the resulting magnetic interactions induce an unusual behavior that can be traced back to an island.....»»
New varactor enhances quantum dot device measurements at millikelvin temperatures
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequenc.....»»

New research using neural networks, a form of brain-inspired AI, proposes a solution to the tough challenge of modeling the states of molecules......»»
Study uncovers condensed-matter dark states in a quantum system with two pairs of sublattices
Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to interferences between the pathways through which a system int.....»»
A maximally entangled quantum state with a fixed spectrum does not exist in the presence of noise, mathematician claims
For more than 20 years, quantum researchers have wondered whether a quantum system can have maximum entanglement in the presence of noise. A mathematician from Spain recently answered the question: No......»»
Researchers observe Floquet states in colloidal nanoplatelets driven by visible pulses
Solution-processed semiconductor nanocrystals are also called colloidal quantum dots (QDs). While the concept of size-dependent quantum effects had long been known to physicists, a sculpture of the theory into real nanodimensional objects remained im.....»»
Study finds European attitudes shifted after Ukraine invasion
An ongoing survey captures how the Russian invasion of Ukraine affected attitudes in European countries not directly involved in the conflict......»»
The closest thing to C-3PO can be yours – if you have $16,000
