Introduction to Quantum Information Theory
... Quantum computation and information studies how information is encoded in nature according to the laws of quantum mechanics and what this means for its computational power. In this note, we present a short and rather schematic introduction to quantum information theory by drawing comparisons to clas ...

A major obstacle is that the dimension of the solution space of such systems is not constant as the parameters vary. This ...
