Credit: Unsplash.Most materials can be classified into two categories based on their subatomic particles: metals and insulators. Like copper and iron, metals possess free-flowing electrons that enable them to conduct electricity, while insulators, such as glass and rubber, tightly bind their electrons, making them non-conductive.The intriguing aspect of insulators is that they can be...

Credit: CC0 Public DomainA team of scientists from the University of Cambridge, along with researchers from the United States, Israel, and Austria, have developed a theory that could generate high-energy "quantum light" to study new properties of matter at the atomic level.They have reported their findings in the journal Nature Physics. While classic...
A single free electron propagates above the special layered structure that the researchers engineered, only a few tens of nanometers above it.During its movement, the electron emits discrete packets of radiation called "photons". Between the electron and the photons it emitted, a connection of "quantum entanglement" is formed. Credit: Ella Maru StudioResearchers from the...
An intuitive illustration of our theorem. Assume the state we consider has dimension d and is coupled with an environment with dimension k. We use three balls to represent the states, whereas the outer one contains all the states.Quantum entanglementQuantum entanglement is a process through which 2 particles become entangled and remain linked...
In Borromean rings, each circle holds the pattern together by passing through the other two circles. Credit: Alexandr Kakinen / Aalto UniversityResearchers have demonstrated how three vortices can be linked to prevent them from being dismantled. The structure of the links resembles a pattern used by Vikings and other old cultures. However, this research...
Entangled drumheads. Credit: Aalto UniversityNew researches expand the boundaries of physics, reaching quantum entanglement in larger systems. Perhaps, even getting around the Heisenberg uncertainty principle.Recently released research pushes the boundaries of crucial concepts in quantum mechanics. Studies from 2 various groups utilized little drums to demonstrate that quantum entanglement. This is an effect generally...
Researchers at Princeton found that a material known as a topological insulator, made from the elements bismuth and bromine, exhibit specialized quantum behaviors normally seen only under extreme experimental conditions of high pressures and temperatures near absolute zero.
