Controlling laser polarization without moving parts

A research team led by UCLA electrical engineers has developed a new technique to control the polarization state of a laser that could lead to a new class of powerful, high-quality lasers for use in medical imaging, chemical sensing and …

Quantum Computers May Have Higher Potential Speeds

A theorist at the National Institute of Standards and Technology (NIST) has shown that, if quantum computer are fully realized, there may be fewer limits to their speed than previously put forth. The findings—described as a “thought experiment” by NIST’s …
