Despite steady improvements in quantum computers, they're still noisy and error-prone, which leads to questionable or wrong answers. Scientists predict that they won't truly outcompete today's ...

A team of engineers, physicists and quantum specialists at Google Research has found that reducing noise to a certain level allows the company's sycamore quantum chip to beat classical computers ...

Dec. 11, 2024 — A new paper published in Nature demonstrates, for the first time, two connected quantum processing units (QPUs) working together to execute a quantum circuit that neither could handle ...

Quantum circuits are systems consisting of logic gates that operate on quantum bits (qubits) to process information and perform calculations based on principles of quantum mechanics. Quantum circuits ...

This diagram illustrates how the team reduces quantum circuit complexity in machine learning using three encoding methods—variational, genetic, and matrix product state algorithms. All methods ...

NINETEEN seconds. That is how fast IBM’s Nighthawk r2 quantum processor completed a computing test that researchers estimate would require about 110 years to reproduce on the Frontier supercomputer.

Quantum machine learning has been one of the most tantalizing promises in computational finance: the idea that qubits, ...
