Mathematicians created a statistical model that can be used to detect misinformation in social posts.

While the number of qubits and the stability of quantum states are still limiting current quantum computing devices, there are questions where these processors are already able to leverage their enormous computing power. Scientists used a quantum processor to simulate the ground state of a so-called toric code Hamiltonian -- an archetypical model system in modern condensed matter physics, which was originally proposed in the context of quantum error correction.

Light not only plays a key role as an information carrier for optical computer chips, but also in particular for the next generation of quantum computers. Its lossless guidance around sharp corners on tiny chips and the precise control of its interaction with other light are the focus of research worldwide. Scientists have now demonstrated the spatial confinement of a light wave to a point smaller than the wavelength in a 'topological photonic crystal.'

Scientists have collaborated to build a structurally-motivated deep learning method built from recent advances in neural language modeling. The team's deep-learning model, called D-SCRIPT, was able to predict protein-protein interactions (PPIs) from primary amino acid sequences.

Physicists said they have finally experimentally documented quantum spin liquids, a long sought-after exotic state of matter. The work marks a big step toward being able to produce this elusive state on demand and to gain a novel understanding of its mysterious nature.
