Qubit thermodynamics

Research output: Contribution to journalArticle


Entropy had been rooted in thermodynamics. We have to explore this background of the microscopic q-entropy. We do not hesitate to apply thermodynamics to a single qubit if we recall the classical ideal gas where thermodynamical equations are satisfied by the microscopic state of each single molecule. Since thermal environment is natural for a physical qubit, further notions of thermodynamics, like thermalization, refrigeration, or the Carnot cycle, apply to qubits. Their significance for q-information is a delicate challenge.
