Solving problems on a quantum chessboard

Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate ...

D-Wave and predecessors: From simulated to quantum annealing

The D-Wave computer is currently the latest link of a long chain of computers designed for the solution of optimization problems. In what sense does it realize quantum computation? We describe the evolution of such computers ...

Can bees color maps better than ants?

In mathematics, you need at most only four different colors to produce a map in which no two adjacent regions have the same color. Utah and Arizona are considered adjacent, but Utah and New Mexico, which only share a point, ...

Smart algorithms boost planning

Organizing care services is a complex task and a lot of planning goes into ensuring that they operate smoothly. Developed by adiutaByte, a spin-off project of the Fraunhofer Institute for Algorithms and Scientific Computing ...
