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

To explore the role of structured vacuum in facilitating projective measurements without significant thermodynamic costs.
Investigated the properties of structured vacuums in quantum systems.
Analyzed the interaction between pointer qubits and oscillators in engineered environments.
Classified measurements within the Shahbeigi–Mohammady hierarchy.
Structured vacuum eliminates common thermodynamic bottlenecks in projective measurements.
Demonstrated type-III operation classification with projective outcomes.
Connected projective ground-state preparation to measurement-powered thermal machines.

Recent no-go theorems — by Guryanova, Friis Elouard et al., 2026) and defines a broader class of topological measurement engines.
