Dicke state generation via selective interactions in a Dicke-Stark model.
We present a method for selective interactions in the Dicke-Stark model using time-dependent perturbation theory. This approach enables the creation of high-fidelity Dicke and Greenberger-Horne-Zeilinger states through controlled Rabi oscillations.
Area of Science:
- Quantum Optics
- Atomic Physics
- Quantum Information
Background:
- The Dicke-Stark model describes interactions between atoms and light fields.
- Controlling quantum states is crucial for quantum information processing.
Purpose of the Study:
- To develop a method for creating selective interactions within the Dicke-Stark model.
- To demonstrate the creation of specific quantum states like Dicke and Greenberger-Horne-Zeilinger (GHZ) states.
Main Methods:
- Utilizing time-dependent perturbation theory.
- Employing a rotating framework to analyze time-oscillating terms.
- Investigating second-order selective interactions.
Main Results:
- Time-oscillating terms were found to depend on atomic and photonic excitations.
- Selective Rabi oscillations between states were achieved by tuning the two-level system frequency.
- High-fidelity Dicke and GHZ states were numerically demonstrated.
Conclusions:
- The proposed method effectively creates selective interactions in the Dicke-Stark model.
- Precise control over frequency and evolution time allows for the generation of complex quantum states.
- This technique offers a pathway for advancing quantum state preparation.
