Beyond the No‑Go Theorems: Structured Vacuum as a Thermodynamic Resource for Projective Ground‑State Preparation

Key Points

• To explore the potential of structured vacuum as a resource for projective ground-state preparation in thermodynamics.
• Analysis of no-go theorems related to projective measurements and thermodynamic resources.
• Demonstration of measurements conducted in engineered structured vacuum environments.
• Classification of measurements within the Shahbeigi–Mohammady hierarchy.
• Identified structured vacuum as a resource eliminating thermodynamic bottlenecks in measurements.
• Established that structured vacuum influences measurement back-action, converting heat to work.
• Connected projective ground-state preparation to measurement-powered thermal machines.
