The Theremin was one of the first electronic musical instruments, yet it provides a degree of expressive real-time control that remains lacking in most modern electronic music interfaces. Underlying the deceptively simple capacitance measurement used by it and its descendants are a number of surprisingly interesting current transport mechanisms that can be… (More)
We introduce a new class of dynamical systems, analog generalizations of linear feedback shift registers, that can be designed with any number of degrees of freedom, generate optimal pseudo-random noise, and exhibit nonlinear dis-sipative entrainment which can be used to decode signals in communication and measurement applications.

We show that quantum computation is possible with mixed states instead of pure states as inputs. This is performed by embedding within the mixed state a subspace that transforms like a pure state and that can be identiied by labeling it based on logical spin, temporal, or spatial degrees of freedom. This permits quantum computation to be realized with bulk… (More)
There is a growing sense that the Digital Divide and the role of Information and Communications Technology (ICT) in international development need to be fundamentally reconceptualized. This paper presents the composition and the rationale behind the creation of a network of fabrication laboratories, FAB LABs, whose mission is to provide concrete examples… (More)
Acknowledgments No dissertation emerges in a vacuum, and this particular one wouldn't have even left the ground were it not for the enormous web of support, both intellectual and personal, that surrounds me. To begin with, I would like to express my enormous gratitude to all of the members of the DEMO Lab with whom I have had the pleasure of collaborating… (More)
—Analog Logic circuits work on digital problems using an analog representation of the digital variables, relaxing the state space of the digital system from the vertices of a hypercube to the interior. This lets us gain speed, power, and accuracy over digital implementations. Logic Automata are distributed, scalable and programmable digital computation… (More)
