Contribution

It presents a new analysis and control scheme for quantum systems using a coupled probe and initial state preparation, expanding control methods in quantum mechanics.

Findings

Quantum systems can be controlled through probe state-dependent coherent control.

The proposed scheme integrates control and state preparation techniques.

Abstract

We present a new analysis on the quantum control for a quantum system coupled to a quantum probe. This analysis is based on the coherent control for the quantum system and a hyperthesis that the probe can be prepared in specified initial states. The results show that a quantum system can be manipulated by probe state-dependent coherent control. In this sense, the present analysis provides a new control scheme which combines the coherent control and state preparation technology.
