Quantum computers can solve problems that would be impossible for classical machines, but this ability comes with a caveat: if a quantum computer gives you an answer, how do you know it’s correct?

Quantum computers can explore every possible solution to a problem at the same time. We’re getting closer to having practical quantum computers – here’s what they will be used for Home ...

Over time, the increased entanglement of the system makes it hard for a classical computer to simulate. However, in a closed system, there's only so much energy to go around.

In theory, quantum computers could solve problems beyond the most powerful classical computer. But such devices will need to become much larger and more reliable first. (Image credit: adventtr ...

For instance, in the classical world, water can either be ice or liquid water at a given time—it cannot be both. But in the ...

PALO ALTO, Calif., March 12, 2025--D-Wave Quantum Inc. (NYSE: QBTS) ("D-Wave" or the "Company"), a leader in quantum computing systems, software, and services and the world’s first commercial ...

In “Polynomial-Time Algorithms for Prime Factorization and Discrete Logarithms on a Quantum Computer,” Shor showed how, using a hypothetical quantum computer, you could efficiently solve ...

Although quantum processors exist today, they are still a long way off from becoming practical replacements for classical computers. This is due to many practical considerations, not the least of w… ...

D-Wave is about to make waves. The quantum computing firm announced on Wednesday that, for the first time, it was able to “successfully simulate the properties of magnetic materials” using its ...

At the same time, it is what makes them a very powerful tool to solve optimization problems, exploring multiple solutions at the same time, faster and more efficiently that classical computers can ...
