Analysis
This paper investigates the thermodynamic cost, specifically the heat dissipation, associated with continuously monitoring a vacuum or no-vacuum state. It applies Landauer's principle to a time-binned measurement process, linking the entropy rate of the measurement record to the dissipated heat. The work extends the analysis to multiple modes and provides parameter estimates for circuit-QED photon monitoring, offering insights into the energy cost of information acquisition in quantum systems.
Key Takeaways
- •Applies Landauer's principle to continuous quantum measurements.
- •Establishes a link between the entropy rate of the measurement record and the dissipated heat.
- •Provides parameter estimates for circuit-QED photon monitoring.
- •Explores the thermodynamic cost of information acquisition in quantum systems.
