Abstract: Combinatorial optimization problems (COPs) are prevalent in various domains and present formidable challenges for modern computers. Searching for the ground state of the Ising model emerges ...

Carmen Dell’Orefice, a cover girl since the 1940s, is the star of a new book. Plus, Levi’s and Barbour team up, and a podcaster who has a lot to say about clothes. By Yola Mzizi In the Fashion Chatter ...

Quantum computers promise speed, but they still struggle with reliability. Qubits are sensitive, and small disturbances can scramble a calculation before it finishes. One way to address that fragility ...
