## Contribution

It introduces a method for nonlocal control of light's quantum state using entanglement and quantum non-demolition impact, advancing remote quantum state manipulation.

## Key findings

- Demonstrates remote quantum state control of light
- Utilizes entanglement for nonlocal manipulation
- Employs quantum non-demolition impact for state preservation

## Abstract

The work is dedicated to the challenge: control and manipulation of the quantum state of a remote physical object. The goal is approached via the entanglement channel between the object and a local physical system - actuator - subjected to a quantum non-demolishing impact. Physical systems under exploration are light beams.
