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.

Visualization of quantum dots in bilayer graphene using scanning tunneling microscopy and spectroscopy reveals a three-fold symmetry. In this three-dimensional image, the peaks represent sites of high amplitude in the waveform of the trapped electrons.

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 […]

In a new theoretical study, Caltech physicists have shown how molecules can, in theory, be used to reduce errors in quantum computing. This strategy would involve placing a rotating molecule in “superposition,” which means that it would exist in multiple orientations at once. In this illustration, three different molecular orientations […]
