Josephson junctions are fundamental components in many superconducting quantum devices, including the qubits that form the heart of quantum computers. As the field of quantum computing rapidly advances, understanding and improving the performance of these crucial components becomes a priority. A central challenge lies in detecting and characterizing Josephson radiation, a high-frequency alternating current generated…
Sandia Labs wants you to meet the “mother of all motion sensors”
Peel apart a smartphone, fitness tracker, or virtual reality headset, and you’ll find a tiny motion sensor tracking its position and movement. Similar larger, more expensive versions exist that are about as big as a grapefruit and a thousand times more accurate. These devices aid GPS-assisted navigation in ships, airplanes, and other vehicles. Now imagine…
How charge density waves could pave the way to faster, more efficient electronic devices
Scientists at Argonne National Laboratory report an advance in the quest for energy-efficient computing. Their latest research, published in Physical Review Letters, focuses on charge density waves, wave-like patterns of electrons. Using a novel microscopy technique, the researchers succeeded in manipulating these waves, potentially paving the way for a new generation of supercomputers that sip…
