Inexpensive chip-based device may transform spectrometry

Spectrometers—devices that distinguish different wavelengths of light and are used to determine the chemical composition of everything from laboratory materials to distant stars—are large devices with six-figure price ...

Superconducting circuits, simplified

Computer chips with superconducting circuits—circuits with zero electrical resistance—would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive ...
