Cycle detection in directed graphs, topological sort, Kahn’s algorithm. These are the ones that feel simple until you’re implementing them and something quietly goes wrong. Same idea as BFS: try to ...

Abstract: Machine vision plays a crucial role in Earth observation. As a fundamental and challenging task in vision systems, image registration faces new challenges due to increasing collaborative and ...

Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting ...

The use of programmed digital computers as general pattern classification and recognition devices is one phase of the current lively interest in artificial intelligence. It is important to choose a ...

ANAHEIM, CALIF. — At the world’s largest gathering of physicists, a talk about Microsoft’s claimed new type of quantum computing chip was perhaps the main attraction. Before the talk, the chair of the ...

In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built ...
