Accessible information in quantum measurement
N. J. Cerf, C. Adami
The amount of information that can be accessed via measurement of a quantum system prepared in different states is limited by the Kholevo bound. We present a simple proof of this t…
Negative entropy in quantum information theory
Nicolas J. Cerf, Chris Adami
We present a quantum information theory that allows for the consistent description of quantum entanglement. It parallels classical (Shannon) information theory but is based entirel…
Propagation of Information in Populations of Self-Replicating Code
Johan Chu, Chris Adami
We observe the propagation of information in a system of self-replicating strings of code (``Artificial Life'') as a function of fitness and mutation rate. Comparison with theoreti…
Quantum Information Theory of Entanglement and Measurement
Nicolas J. Cerf, Chris Adami
We present a quantum information theory that allows for a consistent description of entanglement. It parallels classical (Shannon) information theory but is based entirely on densi…
Quantum Mechanics of Measurement
N. J. Cerf, C. Adami
An analysis of quantum measurement is presented that relies on an information-theoretic description of quantum entanglement. In a consistent quantum information theory of entanglem…
Physical Complexity of Symbolic Sequences
C. Adami, N. J. Cerf
A practical measure for the complexity of sequences of symbols (``strings'') is introduced that is rooted in automata theory but avoids the problems of Kolmogorov-Chaitin complexit…
