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

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 ...

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

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

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 ...

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 ...

IN 2013 GOOGLE and NASA, America’s space agency, launched a quantum computing lab. The idea was to use a specialised quantum ...
