In Race to Build Quantum Computing Hardware, Silicon begins to Shine

Silicon-based device in development for use in quantum computers. Gate electrodes shown in blue, red, and green are used to define the quantum dot potentials while the micromagnet on top provides a magnetic field gradient. The image was taken using scanning electron microscopy and the colors were applied for clarity. Credit: Adam Mills, Princeton University

Research conducted by Princeton University physicists is paving the way for the use of silicon-based technologies in quantum computing, especially as quantum bits—the basic units of quantum computers. This research promises to accelerate the use of silicon technology as a viable alternative to other quantum computing technologies, such as superconductors or trapped ions.

In research published in the journal Science Advances, Pr...

Over the last two decades, scientists have discovered unusual ridge networks on Mars using images from spacecraft orbiting the Red Planet. How and why the ridges formed and what clues they may provide about the history of Mars has remained unknown.

A team of scientists, led by Aditya Khuller of Arizona State University’s School of Earth and Space Exploration and Laura Kerber of NASA’s Jet Propulsion Laboratory, set out to learn more about these ridges by mapping a large area of Mars with th...

A new biodegradable gel improves the immune system’s ability to keep cancer at bay after tumors are surgically removed. The gel, tested in mice, releases drugs and special antibodies that simultaneously deplete immune-blocking cells called macrophages from the surgical site and activate Tcells so they can attack cancer.

University of Wisconsin–Madison scientists tested the gel on mouse models of several cancers...
