Abstract: One of the astounding consequences of quantum mechanics is that it allows the detection of a target using an incident probe, with only a low probability of interaction of the probe and the target. This ‘quantum weirdness’ could be applied in the field of electron microscopy to generate images of beam-sensitive specimens with substantially reduced damage to the specimen. A reduction of beam-induced damage to specimens is especially of great importance as it enables imaging of biological specimens with atomic resolution.

“There is widespread belief that fundamental ideas from QIS will lead to useful new information technology, and provide computing, communication, and control systems beyond the limits of traditional paradigms. These carry with them profound social implications. This is why iQuISE will incorporate education in ethics and social context.”
