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.....»»
Superconductivity study confirms existence of edge supercurrents
Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must.....»»
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.....»»

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.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»
