In solids, the quantum metric captures the quantum coherence of the electron wavefunctions. Recent experiments demonstrate the detection and manipulation of the quantum metric in a noncollinear topological antiferromagnet at room temperature.

Physicists coax molecules into exotic quantum state — ending decades-long quest
The results are “fantastic”, says Yan. They will “really inspire and stimulate the rest of the cold-molecules community”
Exotic phases
Molecular Bose–Einstein condensates could be used in myriad ways. One possibility, says Valtolina, is to create exotic supersolid phases, in which a rigid material flows without resistance. So far this has been achieved only in atomic gases with magnetic interactions — it could now be done in polar molecules, whose interactions are “way stronger”, he says.
Superconducting circuit for qubit control within large-scale quantum computer systems successfully demonstrated
In support of the development of large-scale superconducting quantum computers, researchers with the National Institute of Advanced Industrial Science and Technology (AIST), one of the largest public research organizations in Japan, in collaboration with Yokohama National University, Tohoku University, and NEC Corporation, proposed and successfully demonstrated a superconducting circuit that can control many qubits at low temperature.
Nanoscale Discovery Offers a New, Energy-Efficient Approach to Quantum Computing
A collaborative study by researchers at Lancaster and Radboud universities has pioneered a method to generate and control spin waves at the nanoscale, offering a new, energy-efficient approach to quantum computing.
Researchers at Lancaster University and Radboud University Nijmegen have successfully produced propagating spin waves on the nanoscale, unveiling a new method to modulate and amplify these waves.
Their discovery, published in Nature, could pave the way for the development of dissipation-free quantum information technologies. As the spin waves do not involve electric currents these chips will be free from associated losses of energy.
Teleportation of Quantum Particles and Impact
Explore the fascinating world of quantum teleportation. Discover its principles, applications, and the profound impact it could have on our future.
Introduction to Quantum Teleportation
Quantum teleportation, a term that sounds like it’s straight out of science fiction, is a very real and advancing field in quantum physics. This groundbreaking technology is not about transporting matter from one place to another but rather involves the transfer of information between quantum particles. This article delves into the science behind quantum teleportation, its potential applications, and the impact it could have on various aspects of our lives.
Physicists take molecules to a new ultracold limit, creating a state of matter where quantum mechanics reigns
There’s a hot new BEC in town that has nothing to do with bacon, egg, and cheese. You won’t find it at your local bodega, but in the coldest place in New York: the lab of Columbia physicist Sebastian Will, whose experimental group specializes in pushing atoms and molecules to temperatures just fractions of a degree above absolute zero.
Cambridge Scientists Achieve Long-Sought Quantum State Stability in New 2D Material
Scientists at the Cavendish Laboratory have discovered spin coherence in Hexagonal Boron Nitride (hBN) under normal conditions, offering new prospects for quantum technology applications.
Cavendish Laboratory researchers have discovered that a single ‘atomic defect’ in a material known as Hexagonal Boron Nitride (hBN) maintains spin coherence at room temperature and can be manipulated using light.
Spin coherence refers to an electronic spin being capable of retaining quantum information over time. The discovery is significant because materials that can host quantum properties under ambient conditions are quite rare.
A framework to construct quantum spherical codes
To reliably perform complex, large-scale calculations, computing systems rely on so-called error correction schemes, techniques designed to protect information against errors. These techniques are perhaps even more essential when it comes to quantum computers, devices that perform computations leveraging the principles of quantum mechanics.
