We present a novel method for distributing entanglement across quantum networks without local control. This approach simplifies entanglement distribution by requiring only the preparation of a single network element.

Area of Science:

  • Quantum Information Processing
  • Quantum Communication Networks

Background:

  • Bilateral entanglement is crucial for distributed quantum information processing, enabling efficient communication and computation.
  • Current methods for entanglement distribution often require complex local control across network nodes.

Purpose of the Study:

  • To propose a novel model for entanglement distribution in quantum networks that eliminates the need for local control.
  • To demonstrate the efficiency of this model in both finite and infinite dimensional Hilbert spaces.

Main Methods:

  • The proposed model performs entanglement distribution without requiring local control over individual network elements.
  • The setup relies solely on the proper preparation of a single, designated element within the network.
  • Implementation is suggested using electromechanical systems.

Main Results:

  • The model achieves efficient entanglement distribution in finite and infinite Hilbert spaces.
  • Entangled channels can be established by preparing only one element, simplifying network operations.

Conclusions:

  • The proposed model offers a simplified and efficient method for entanglement distribution in quantum information processing.
  • The use of electromechanical systems provides a practical pathway for implementing this advanced quantum networking protocol.
