Quantum computers have the potential of outperforming classical computers in some optimization and data processing tasks. However, quantum systems are also more sensitive to noise and thus prone to errors, due to the known physical […]

Understanding and reliably measuring the geometric properties of quantum states can shed new light on the intricate underpinning of various physical phenomena. The quantum geometric tensor (QGT) is a mathematical object that provides a detailed […]
Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In quantum technology applications such as quantum computing, light plays a […]
X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters […]
String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a “provable” phenomenon. But a team of physicists has now taken a significant step forward […]
The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of atoms. […]
Claus Lämmerzahl, Professor of Gravitational Physics at the University of Bremen, and Dr. Sebastian Ulbricht, scientist at the Natural Metrology Institute, have proposed in a new article that gravity could be the basis for the […]
A new study in Physical Review Letters demonstrates the levitation of a microparticle using nuclear magnetic resonance (NMR), having potential implications from biology to quantum computing. Click to rate this post! [Total: 0 Average: 0]You […]
For experiments that require ultra-precise measurements and control over atoms—think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates—lasers are the technology of choice, the more spectrally pure (emitting a single color/frequency), the better. Conventional […]
Physicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. […]
