Imagine you are playing the guitar—each pluck of a string creates a sound wave that vibrates and interacts with other waves. Now shrink that idea down to a small single molecule, and instead of sound ...

Novel type of quantum interference enables single-molecule switch with high on/off ratio. Credit: Julia Greenwald and Suman Gunasekaran/Columbia Engineering A single-molecule switch that operates via ...

Scientists made a single-molecule transistor using quantum interference to control electron flow. This new design offers high on/off ratio and stability, potentially leading to smaller, faster, and ...

This study is led by Dr. Junyang Liu and Prof. Wenjing Hong from Xiamen University. The molecular synthesis is done by Prof. Zhong-Ning Chen (State Key Laboratory of Structural Chemistry, Fujian ...

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...
