Bits and q-bits as versatility measures.
Using Shannon information theory is a common strategy to measure any kind of variability in a signal or phenomenon. Some methods were developed to adapt information entropy measures to bird song data trying to emphasize its versatility aspect. This classical approach, using the concept of bit, produces interesting results. Now, the original idea developed in this paper is to use the quantum inf...
متن کاملTangible Bits: Designing the Boundary between People, Bits, and Atoms
Where the sea meets the land, life has blossomed into a myriad of unique forms in the turbulence of water, sand, and wind. At another seashore between the land of atoms and the sea of bits, we are now facing the challenge of reconciling our dual citizenships in the physical and digital worlds. Windows to the digital world are confined to flat square screens and pixels, or ‘painted bits’. Unfort...

متن کاملShaping Bits
The performance of bit-interleaved coded modulation (BICM) with bit shaping (i.e., non-equiprobable bit probabilities in the underlying binary code) is studied. For the Gaussian channel, the rates achievable with BICM and bit shaping are practically identical to those of coded modulation or multilevel coding. This identity holds for the whole range of values of signalto-noise ratio. Moreover, t...
متن کاملWhere to Hide the Bits ?
We present a stochastic two-player zero-sum game between defender and attacker related to the security of practical steganography. The defender wants to hide a message in a cover object drawn by nature. The attacker wants to distinguish plain covers from those with a hidden message. We study the case of n-bit covers, independently but not identically distributed to allow for variation in the pr...
