Quantum supremacy is achieved when a quantum computer can solve problems impractical for classical computers due to time constraints. Quantum computers differ in operation, using qubits that can ...

The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, ...

Quantum computers are expected to solve some problems beyond the reach of the most powerful supercomputers imaginable. Reaching this milestone has been dubbed "quantum supremacy." But whether ...

To achieve quantum supremacy, a quantum computer would have to perform any calculation that, for all practical purposes, a classical computer can’t. In one sense, the milestone is artificial. The task ...

Google’s AI Quantum team announced Wednesday that it had reached an important milestone in quantum computing known as “quantum supremacy” — the point when quantum computers can perform a ...

The Google paper makes clear that while its team has been able to show quantum supremacy in a narrow sampling task, we’re still a long way from developing a quantum computer capable of ...

Google has reached a milestone in computing by achieving "quantum supremacy." Caltech's John Preskill, who coined that term, explains what that means.

Quantum supremacy is a benchmark that was set about seven years ago in 2012 by a physicist named John Preskill at the California Institute of Technology, Caltech.

Still, quantum supremacy is not a straightforward line to be crossed, says quantum physicist Simon Devitt, also of the University of Technology Sydney. Instead, there’s a nebulous buffer zone.

"Quantum supremacy" boils down to a failure of mathematics, combined with a fear that the well will run dry before we’ve drunk our fill. In a perfect world, a quantum computer operates perfectly.

This leads us to the quantum supremacy topic. When you get various learned computer people into a room and they have different ideas about how to do things, invariably they form into opposing camps.
