## Contribution

It introduces an operational protocol using quantum energy teleportation to engineer negative stress-energy densities in quantum fields, showing optimal scaling.

## Key findings

- Protocol creates negative stress-energy densities
- Saturates the quantum interest conjecture
- Operates via light-matter interaction

## Abstract

We use quantum energy teleportation in the light-matter interaction as an operational means to create quantum field states that violate energy conditions and have negative local stress-energy densities. We show that the protocol is optimal in the sense that it scales in a way that saturates the quantum interest conjecture.
