We might imagine that electric current flows as a smooth, even stream of electrons through our electronics devices, but at the quantum scale the flow of electric current might be more accurately pictured as a bubbling brook ...
Stanford physicists have developed a "quantum microphone" so sensitive that it can measure individual particles of sound, called phonons.

In an ironic twist, physicists have shown that the very property that can be used to show that quantum computing devices can solve some problems that classical computers cannot also makes it impossible to efficiently certify ...
According to the rules of quantum mechanics, electrons behave as particles or waves. Similar to the walls of a water reservoir, "electrostatic potential walls" can be created to confine electrons to desired spatial regions, ...

In a recent study now published in Light: Science & Applications, Ming Zhang, Lan-Tian Feng and an interdisciplinary team of researchers at the departments of quantum information, quantum physics and modern optical instrumentation ...
Students learn in high school that molecules must be in contact to react chemically. But what if that's not always true? It's that idea, which challenges textbook "laws," a team of theorists explored. They showed that even ...
