Quantum computers could soon be able to solve genuinely useful mathematical problems faster than classical computers, claims quantum computing firm Quantinuum. It would be the first example of these ...

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

The race to build larger and more powerful quantum computers has mostly focused on engineering: adding more qubits, reducing noise, and keeping fragile quantum states alive. However, a new theoretical ...

IBM and University of Chicago researchers have demonstrated a quantum computing system that they ...

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 ...

Quantum computers promise to solve problems that would take even the fastest conventional supercomputers a vast amount of time, but the quantum information they store and process is extremely ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

Quantum is now a conversation that business leaders are having and this article explores what leaders should be doing to ...

Picture a quantum computer. Are you imagining an ordinary computer, but somehow just better? If so, that would be a mistake, because quantum computers are fundamentally different. They rely on exotic ...

Every week quantum computing hits a new milestone: more qubits, fewer errors, better readout of results. But will these breakthroughs help solve the advanced computational problems facing energy, like ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.

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.
