How Imaginary Numbers Describe the Fundamental Shape of Nature

Several science students may imagine a ball rolling down a hill or a car skidding due to friction as prototypical examples of the systems physicists care about. However, much of modern physics consists of looking for objects and essentially invisible sensations: the small electrons of quantum physics and the particles concealed within odd steels...

A Strange Brand-New Phase Of Matter Developed In Quantum Computers Acts Like It Has Two-Time Dimensions

The Penrose tiling pattern is a type of quasicrystal, which means that it has an ordered yet never-repeating structure. The pattern, composed of two shapes, is a 2D projection of a 5D square lattice.

A Quantum Double-slit Experiment Run with Molecules for the First time

Richard Feynman once stated that the double-slit experiment reveals the central challenges of quantum mechanics, putting us ''up against the and peculiarities of nature and paradoxes and mysteries''.Nandini Mukherjee, Richard Zare, and their co-workers at Stanford University, United States, have currently revealed that when helium (He) atoms collide with deuterium molecules (D2) in a quantum...

Quantum Sensor Can Identify Electromagnetic Signs of Any Frequency

MIT researchers have developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or electrical fields, but until now they have only been capable of detecting a few specific frequencies, limiting their usefulness....

Scientists Invent “Profound” Quantum Sensor That Can Peer Into the Earth

"This Is An 'Edison Moment' In Sensing That Will Improve Society."Credit: Pixabay/CC0 Public DomainGravitationalA significant breakthrough in quantum sensing technology is being explained as an "Edison moment" that could, scientists expect, have embracing implications.New research in Nature explains one of the first practical applications of quantum sensing, a largely theoretical technology that weds quantum...

Laws of Physics bent: Time Crystals “Impossible” but Obey Quantum Physics

In a new experiment, scientists created two time crystals inside the superfluid, and brought them to touch. Credit: SciTechdaily.Time crystals were long considered impractical because their continuous movement would seem to challenge the laws of physics. Utilizing quantum physics, scientists have developed time crystals and now proved that they can power helpful tools in...

Redefining what Information is Vital in Quantum Measurements

Information about a quantum state is split into three information contents (i.e., information gain, disturbance, and reversibility). Credit: Hong et al.Scientists at the Korea Institute of Science and Technology (KIST) have attempted to capture the interaction between different kinds of information that are essential while gathering quantum measurements, specifically information gain, disturbance, and reversibility. Their paper, released...

Scientists Create Odd “Domain Walls” in Laboratory

University of Chicago researchers discovered how to create and manipulate a quantum phenomenon known as a “domain wall” – shown in this image as the lighter line between two groups of atoms. (Image adapted and color added from experiment data). Credit: Illustration by Kai-Xuan YaoControlled for the very first time, the quantum phenomenon might...

Uncovering Concealed Local States in a Quantum Material

Scientists have collected evidence of local symmetry breaking in a quantum material upon heating. They believe these local states are associated with electronic orbitals that serve as orbital degeneracy lifting (ODL) "precursors" to the titanium (Ti) dimers (two molecules linked together) formed when the material is cooled to low temperature. (Electron orbitals are considered...
