Negative Quantum Channels Paperback / softback
by James M. McCracken
Part of the Synthesis Lectures on Quantum Computing series
Paperback / softback
Description
This book is a brief introduction to negative quantum channels, i.e., linear, trace-preserving (and consistent) quantum maps that are not completely positive.
The flat and sharp operators are introduced and explained.
Complete positivity is presented as a mathematical property, but it is argued that complete positivity is not a physical requirement of all quantum operations.
Negativity, a measure of the lack of complete positivity, is proposed as a tool for empirically testing complete positivity assumptions.
