A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations
A view of the honeycomb lattice, with a triangular region indicated with the black sites (spheres). The electrons in the model studied by the researchers can jump between sites of…
Small-scale solution could be key to solving large-scale mystery
(Left) The new dark matter detection proposal looks for frequent interactions between nuclei in a detector and low-energy dark matter that may be present in and around Earth. (Right) A…
Physicists demonstrate parity anomaly in a topological insulator
Schematic of the device used in the experiment. The re-entrant quantum Hall effect, where the electrical resistance goes back and forth when the magnetic field is increased, is a signature…
Scientists on the hunt for evidence of quantum gravity’s existence at the South Pole
Credit: Pixabay/CC0 Public Domain Several thousand sensors distributed over a square kilometer near the South Pole are tasked with answering one of the large outstanding questions in physics: does quantum…
Entanglement entropies of nuclear systems found to grow as the volume of those systems
Left: partitions where the set of blue points occupy one region and the set of black points another region, similar to how many systems work. Right: the partitions that occur…
Harnessing the power of virtual quantum broadcasting
A virtual broadcasting map can have a significant impact on quantum information processing. Credit: Fractal Hassan/Unsplash In a new study, scientists propose the concept of “virtual quantum broadcasting,” which provides…
