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…
Accelerating waves reveal physics mysteries
Newswise — Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena. For…
Fast radio burst sets record, paving the way to weigh the Universe.
Newswise — In a paper published today in Science, a global team led by Macquarie University’s Dr Stuart Ryder and Swinburne University of Technology’s Associate Professor Ryan Shannon, report on their discovery…
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…

Manipulating nonlinear exciton polaritons in an atomically-thin semiconductor with artificial potential landscapes
Newswise — Exciton polaritons, hybrid quasiparticles caused by the strong exciton-photon coupling, constitute a unique prototype for studying many-body physics and quantum photonic phenomena traditionally in cryogenic conditions. Atomically thin…
Phonon engineering in Yb:La2CaB10O19 crystal for extended lasing beyond the fluorescence spectrum
Newswise — Electron and phonon are two fundamental particles (quasi-particles) of condensed matter and their interplay in single crystals can create many interesting physical phenomena, such as polariton, charge density…
