Quantum annealing (QA) is a cutting-edge algorithm that leverages the unique properties of quantum computing to tackle complex combinatorial optimization problems (a class of mathematical problems ...

Discover the latest articles and news in related subjects. These are most likely near points where the instantaneous gap to excited states ΔE attains a minimum as a function of Γ; further, ΔΓ is ...

Gate-based quantum computers, such as the one that IBM is building, remain short of enough qubits to run problems that are relevant to the real world. Quantum technologies have long been pitched as a ...

Dr. James McCaffrey of Microsoft Research explains a new idea that slightly modifies standard simulated annealing by borrowing ideas from quantum mechanics. The goal of a combinatorial optimization ...

The D-Wave quantum annealer isn’t a general-purpose computer, in that it can only solve a set of problems that can be structured as energy minimizations. And even on those problems, D-Wave employees ...

In computer science, normally we care about asymptotic speedup: We care about, “What is your running time as a function of the size of the problem? Does it grow linearly? Does it grow quadratically?” ...

If you want to simulate a tic-tac-toe game, that’s easy. You can evaluate every possible move in a reasonable amount of time. Simulating antennas, however, is much harder. [Rosrislav] has been ...
