A review of thousands of scientific papers about quantum computers finds that most don’t provide code that can be tested on ...

Quantum computing should be viewed as a powerful new tool for solving specific classes of exceptionally difficult problems.​ ...

Quantum computing is moving beyond the research stage as companies look for ways to turn experimental systems into commercial ...

Just days after Quantinuum’s first earnings report as a public company, the quantum leader unveils a partnership with ...

Quantum computing is a huge growth opportunity for IBM, and in a few years the company may begin to reap significant benefits ...

Using light to process quantum information is one of the most promising approaches to building future quantum computers.

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but proving quantum advantage in an absolute sense is difficult. All three ...

If the goal is to make quantum systems act like powerful classical machines, then today’s quantum computers may be too classical for their own good.

This 169-page strategic study delivers an exhaustive evaluation across photonic chip technologies (silicon photonics, lithium niobate), QPU cloud access models, quantum-AI convergence, and enterprise ...

The truth is less dramatic. There are three ways that AI and quantum computers overlap: first, in the problems they try to solve; second, in the way each can be used to build the other; and third, in ...

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...
