Original artwork by Ludmila Odintsova Lasers were created 60 years ago this year, when three different laser devices were unveiled by independent laboratories in the United States. A few years later, one of these inventors called the unusual light sources “a solution seeking a problem”. Today, the laser has been […]

Professor of physics Andrew Jordan and his colleagues will use superconducting circuits to design experiments that can be carried out within a realistic quantum system, with the goal of studying concepts that are currently poorly understood in quantum mechanics.

On the left is a representation of a grid of heptagons in a hyperbolic space. To fit the uniform hyperbolic grid into “flat” space, the size and shape of the heptagons are distorted. In the appropriate hyperbolic space, each heptagon would have an identical shape and size, instead of getting […]

Probing the reality of observations made by an artificial quantum intelligence. Credit: Artwork by Anthony Dunnigan. Quantum physicists at Griffith University have unveiled a new paradox that says, when it comes to certain long-held beliefs about nature, “something’s gotta give.” Quantum theory is practically perfect at predicting the behavior we […]

Light propagates through the atomic cloud shown in the center and then falls onto the SiN membrane shown on the left. As a result of interaction with light the precession of atomic spins and vibration of the membrane become quantum correlated. This is the essence of entanglement between the atoms […]

Planetary nebula NGC 2440’s central star, HD62166, is possibly the hottest known white dwarf star discovered yet. White dwarfs exhibit puzzling quantum phenomena: As they gain mass, they shrink in size. Credit: NASA/JPL/STScI/AURA A team led by students probes the mass-radius relation of white dwarf stars, observing in their data evidence of […]

Schematic diagram showing both the magnetism and the conductive behavior on the surface of MnBi2Te4. The magnetism points uniformly upward, as shown by the red arrows, and the surface electrons, represented by the hourglass structures, are conductive because the top and bottom halves touch at the vertex with no ‘gap’ […]
