By analyzing images made of colored dots created by quantum simulators, ETH researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for […]
In daily life, when two objects are “indistinguishable,” it’s due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ball is […]
Insider Brief Terra Quantum announced the launch of TQ42 Cryptography, an open-source post-quantum cryptography library. The suite of quantum-resistant algorithms is designed to help businesses protect their data from current and future security threats. Experts […]
Since the discovery of quantum mechanics more than a hundred years ago, it has been known that electrons in molecules can be coupled to the motion of the atoms that make up the molecules. Often […]
Proteins are the molecular machines that sustain every cell and organism, and knowing what they look like will be critical to untangling how they function normally and malfunction in disease. Now researchers have taken a […]
In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, […]
Quantum 8, 1341 (2024). https://doi.org/10.22331/q-2024-05-08-1341 We propose an analogue of $text{SU}(1,1)$ interferometry to measure rotation of a spin by using two-spin squeezed states. Attainability of the Heisenberg limit for the estimation of the rotation angle […]
A large international team of physicists working on the BES III collaboration has announced possible physical evidence of glueballs. In their study, published in the journal Physical Review Letters, the group analyzed decaying particles in […]
A team of researchers from the 5th Institute of Physics at the University of Stuttgart is making important progress in the field of quantum simulation and quantum computing based on Rydberg atoms by overcoming a […]
Insider Brief Researchers report they achieved the fractional quantum anomalous Hall state of photons for the first time. The team suggests this is a step they say will have implications for the development of fault […]
