Quantum Heat Engines
Let’s start with classical physics. A heat engine is a system that extracts useful work from heat energy flowing between two sources at different temperatures. The steam engine is a….

Quantum Mutual Information
Let’s begin with the basic idea of mutual information from classical information theory. It tells us how much knowing one variable tells us about another. For example, if you know….
Quantum Entropy Measures
In classical information theory, entropy is used to measure uncertainty or the average information content of a message. This idea is extended in the quantum world through quantum entropy measures,….
