QnAs with Christopher Monroe.

Classic computing can take credit for technology ranging from mobile phones to supercomputers. But in recent years, a budding counterpart to these conventional devices has emerged: quantum computers. Whereas classic computing sometimes fails to solve complex calculations, such as factoring hundred-digit numbers, quantum computing holds the potential to easily tackle such problems. The field of ...

Adaptive Flight Control Experiments using RAVEN

This paper discusses a new flight test facility at MIT known as the Real-time indoor Autonomous Vehicle test ENvironment (RAVEN) which enables the exploration of aggressive aerobatic flight with relatively low risk. A key feature of this work is that the control algorithms are often the limiting factor because the flight dynamics are highly nonlinear and not well known, and they can change with...
