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?

IBM, which is working on its own quantum computer design, argued that the random number generator task completed by Google's 'Sycamore' quantum computer is technically achievable on a classical ...

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.

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 ...

An illustration of a quantum system that was simulated by both classical and quantum computers. The highlighted sections show how the influence of the system’s components is confined to nearby ...

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 ...

A D-Wave quantum computer equipped with a quantum annealing processor (shown) tackled a real-world problem that would stymie a classical supercomputer, researchers claim.

PALO ALTO, Calif., May 20, 2025--D-Wave Quantum Inc. (NYSE: QBTS) ("D-Wave" or the "Company"), a leader in quantum computing systems, software, and services, today announced the general ...

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 ...
