Consequently, IBM is the better value. Combined with its Nighthawk processor moving the company toward quantum advantage next ...

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?” ...

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 ...

Are powerful quantum computers finally here? Google is claiming that its D-Wave quantum computer can solve certain problems 100 million times faster than an ordinary computer, a result that it says ...

Wang Chao and his colleagues at Shanghai University have announced that they have developed a method to break RSA encryption, a cryptography whose security is based on the difficulty of prime ...

Some math problems are so complicated that they can bog down even the world’s most powerful supercomputers. But a wild new frontier in computing that applies the rules of the quantum realm offers a ...

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 ...
