Two decades ago, the mathematician Moon Duchin spent her summers teaching geometry at Mathcamp, a program for mathematically talented teens. Campers contemplated notions such as how to prove whether a ...

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number ...

IBM achieves record 120-qubit entanglement, marking a leap toward quantum systems that could one day challenge Bitcoin’s ...

IBM scientists entangled 120 qubits in a single coherent “cat state,” a record-breaking feat in quantum computing.

UC Santa Barbara computer scientist Daniel Lokshtanov is advancing fundamental understanding of computational efficiency through groundbreaking research on quasi-polynomial time algorithms, supported ...

Daniel Lokshtanov’s work explores the limits of what computers can solve, paving the way for advances in artificial intelligence and computational efficiency.

Abstract: For accelerating the convergence of numerical computation of sparse matrices, the classical approach is to partition sparse matrices into block-diagonal structures by graph partitioning ...

Abstract: Existing graph adversarial defense algorithms cannot recover the implicit relationships of a bipartite graph that have been disrupted by adversarial attacks. To address this issue, this ...
