The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Identifying quantum phases of matters has quantum computers stumped and could represent a boundary to physical observation ...

It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true.

Google says its quantum computer achieved a verifiable calculation that classic computers cannot. The work could point to future applications.

It would take normal computer 10,000 years to solve the same problem. Google announced Wednesday it designed a machine that would take only 200 seconds to solve a problem that the world's fastest ...
