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 ...

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 ...

Big Four firm Ernst and Young announced it now has a quantum computer physically sitting in its Toronto office.

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

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

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 ...

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...

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 ...

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

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.
