Single Abrikosov vortices as quantized information bits

Superconducting digital devices can be advantageously used in future supercomputers because they can greatly reduce the dissipation power and increase the speed of operation. Non-volatile quantized states are ideal for the realization of classical Boolean logics. A quantized Abrikosov vortex represents the most compact magnetic object in superconductors, which can be utilized for creation of hi...

Extraction of optimally unbiased bits from a biased source

| We explore the problem of transforming n independent and identically biased f?1; 1g-valued random vari-so that this result is as unbiased as possible. In general, no function f produces a completely unbiased result. We perform the rst study of the relationship between the bias b of these X i and the rate at which f(X 1 ; : : : ; Xn) can converge to an unbiased f?1;1g random variable (as n ! 1...

Source Requantization: Successive Degradation and Bit Stealing

We consider source requantization in tw oforms | successive degradation (i.e., source delity reduction) and bit stealing (i.e., information embedding) | when no forward planning has been done to facilitate the requantization. We focus on nite-alphabet sources with arbitrary distortion measures as well as the Gaussian-quadratic scenario. F orthe successive degradation problem, w e show an ac hie...

Generating random bits from an arbitrary source: fundamental limits

Suppose we are given a random source and want to use it as a random number gene.rator; at what rate can we generate fair bits from it? We address this question in an informationtheoretic setting by allowing for some arbitrarily small but nonzero deviation from “ideal” random bits. We prove our results with three different measures of approximation between the ideal and the obtained probability ...

Stealing (From) the Music Industry

The record industry is desperately trying to cope with the spread of peer-to-peer (P2P) systems and salvage its business model. Meanwhile, these same P2P networks present a tremendous opportunity for technology companies to reinvent consumers’ relationship with music. I argue that a new business model based on open content can be just as revolutionary for the way society interacts with music as...
