Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

Abstract: The dynamic behavior of a mixed spin-1/2 and spin-3/2 Ising model with a crystal-field interaction in the presence of a time-varying magnetic field on alternate layers of hexagonal lattice ...

For the alternating spin chain model, the researchers used so-called Clar's goblets as their starting material, hourglass-shaped nanographene molecules consisting of eleven carbon rings.

(Image: Empa) The two Heisenberg experiments highlight this approach. For the alternating spin chain model, the researchers used so-called Clar's goblets as their starting material, hourglass-shaped ...

This algorithm incorporates the following key innovations: Quantum Bit Reuse Strategy: By utilizing the compact representation of matrix product states (MPS), the D-dimensional spin system is ...

Call it what you will, but the DeepSeek foundation model has in one short week turned the AI world on its head, proving once again that Chinese researchers can make inferior hardware run a superior ...

“Algorithms often operate as proprietary secrets, making transparency a challenge,” noted Cao Wei, a commercial law professor at Southwest University of Political Science and Law, in the southwestern ...

For instance, if the model is working its way through a book, the hidden state values will be things like representations of words (or parts of words). “If you think of a transformer as an ...

Research uses the Ising model, Monte Carlo method, and Metropolis algorithm. The model considers a two-layer film made of a non-magnetic conductor and a conductive antiferromagnetic film.

A new algorithm has dramatically shortened that ... To produce such a stable equilibrium, scientists "spin-up" their model by essentially letting it run until it stops changing (the system is ...

But a new algorithm I have developed promises ... To produce such a stable equilibrium, scientists “spin-up” their model by essentially letting it run until it stops changing (the system ...
