And finally, shares of QCi are extremely expensive. Its stock has a price-to-sales ratio of about 4,500, making it more ...

The QBI program commenced in 2024 with the goal to build utility-scale quantum computing, or USQC, by 2033. The agency ...

NTT and OptQC aim to build a 1-million qubit quantum computer built on light-based photonics principles (rather than electricity) to enhance the reliability, scalability and practicality of the ...

Scientists looked at how an electrical charge would move through a barrier of silicon, germanium and tin, part a quantum well. They thought the electrical charge would move more slowly, but mobility ...

Nvidia CEO Jensen Huang said Tuesday that expects quantum computing will need traditional processors alongside the new technology—and his company will help make it happen.

D-Wave, IonQ, and Rigetti use different approaches to build quantum computers. All three companies are unprofitable but are generating sales from their quantum systems. The odds are stacked against ...

Quantum computers are still in their infancy. Presently limited to 100 or so error-prone qubits, the quantum equivalents to classical bits, they are far from supreme calculating machines that are ...

A superconductor made from germanium, a material commonly used to build computer chips, could one day create better and more reliable quantum computers. Superconductors are materials that conduct ...

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

Abstract: Benchmarking quantum computers helps to quantify them and bringing the technology to the market. Various application-level metrics exist to benchmark a quantum device at an application level ...

Pure-play quantum stocks have delivered monstrous returns over 12 months, as governments see encryption vulnerability as a security priority. "Q-Day" (when quantum computing breaks most standard ...
