Quantum computing closer to reality with new materials

Vuckovic’s Stanford team is developing materials that can trap a single, isolated electron. Working with collaborators worldwide, they have recently tested three different approaches to the problem, one of which can operate at room temperature – a critical step if …

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 …

Imploding Liner Fusion Propulsion System

NASA advanced innovative concepts has funded Michael LaPointe, NASA Marshall Space Flight Center to develop a fusion propulsion system. It is an innovative modification to magneto-inertial fusion is proposed in which the pulsed, high current magnetic field coil and stationary …

Fusion-Enabled Pluto Orbiter and Lander

The Direct Fusion Drive (DFD) concept provides game-changing propulsion and power capabilities that would revolutionize interplanetary travel. DFD is based on the Princeton Field-Reversed Configuration (PFRC) fusion reactor under development at the Princeton Plasma Physics Laboratory. The mission context we …
