Researchers from Louisiana State University have introduced a smart quantum technology for the spatial mode correction of single photons. In a paper featured on the cover of the March 2021 issue of Advanced Quantum Technologies, the authors exploit the self-learning and self-evolving features of artificial neural networks to correct the distorted […]

Chinese scientists have established the world’s first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a total distance of 4,600 kilometers for users across the country.

A viable quantum internet — a network in which information stored in qubits is shared over long distances through entanglement — would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication. This month, scientists at Fermilab, a U.S. Department of Energy Office […]

MIT and Harvard researchers have studied how elementary units of magnetism, called spins (the black arrows), move around and interact with other spins, in a chain of single atoms (the colored spheres). The background shows a real image of the spins, revealing a high contrast periodic modulation of the blue […]

An electrical current excites the superposition of two magnons with linear polarization (indicated by the red and blue arrows). Subsequently, energy is transported through the antiferromagnetic insulator. This can be detected as electrical voltage.
