There has been an interesting debate on the quantum versus classical origin of ghost imaging in thermal light. To clarify this quantum-classical dilemma, Lixiang Chen at Xiamen University of China formulated a density matrix to […]

Many measurements are limited by standard quantum limit (SQL). SQL is defined as the measured noise levels set by quantum mechanics. Quantum entanglement can be used to beat SQL and approach an ultimate limit called […]
A Russian-U.K. research team has proposed a theoretical description for the new effect of quantum wave mixing involving classical and nonclassical states of microwave radiation. This effect, which previously lacked a rigorous mathematical description, could […]
For decades, scholars have believed that the quantum statistical properties of bosons are preserved in plasmonic systems, and therefore will not create different form of light. Click to rate this post! [Total: 0 Average: 0]You […]
Analog photonic solutions offer unique opportunities to address complex computational tasks with unprecedented performance in terms of energy dissipation and speeds, overcoming current limitations of modern computing architectures based on electron flows and digital approaches. […]
An international team has reported in Nature the first observation of ghost polaritons, which are a new form of surface waves carrying nanoscale light strongly coupled with material oscillations and featuring highly collimated propagation properties. […]
Using computers to study polymers has always been a major challenge for scientific computation, especially for long and densely packed biomolecules, like DNA. New perspectives are now opening up through quantum computing. Scientists have now […]
Physicists at EPFL have found a way to get photons to interact with pairs of atoms for the first time. The breakthrough is important for the field of cavity quantum electrodynamics (QED), a cutting-edge field […]
Over the past few years, many physicists and material scientists worldwide have been investigating the properties and characteristics of magic-angle twisted bilayer graphene (MATBG). MATBG is a strongly correlated material that was first experimentally realized […]
Water is the most abundant yet least understood liquid in nature. It exhibits many strange behaviors that scientists still struggle to explain. While most liquids get denser as they get colder, water is most dense […]
