Scientists amplify superconducting sensor array signals near the quantum limit
Superconducting sensors collecting X-ray or gamma-ray photons that are generated to characterize materials. Amplification using the microwave multiplexer & new quantum-based amplifier enhances the resolution of the signals w/o introducing…
How they work, what they do, and where they’re heading
Credit: CC0 Public Domain In June, an IBM computing executive claimed quantum computers were entering the “utility” phase, in which high-tech experimental devices become useful. In September, Australia’s Chief Scientist…
Electrical control of quantum phenomenon could improve future electronic devices
A new method by Penn State researchers conveniently changes the direction of electron flow in materials that exhibit the quantum anomalous Hall (QAH) effect—a phenomenon in which the flow of…
