A METHOD AND SYSTEM FOR SHARING QUANTUM ENTANGLEMENT BETWEEN DISTANT NODES WITHOUT QUANTUM MEMORIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240048247 titled 'A METHOD AND SYSTEM FOR SHARING QUANTUM ENTANGLEMENT BETWEEN DISTANT NODES WITHOUT QUANTUM MEMORIES
Simplified Explanation
The patent application describes a method for entangling photons in a distributed quantum-based communication system. Here is a simplified explanation of the abstract:
- The method involves generating sets of entangled photon pairs between multiple remote nodes (nodes a and nodes b) and a central entangling node (node c).
- Nodes a and b are capable of both quantum communication and classical communication with node c.
- One photon from a first entangled photon pair set is transmitted to node a, and one photon from a second entangled photon pair set is transmitted to node b, each over the associated quantum channels.
- Bell-state measurements are performed between the other photon of the first entangled photon pair and the other photon of the second entangled photon pair.
- If the photons arrive at about the same time with about the same frequency, then the photon pairs are marked as being entangled.
Potential applications of this technology:
- Quantum communication systems: The method can be used in the development of secure and efficient quantum communication systems.
- Quantum cryptography: Entangled photon pairs can be used for secure key distribution in quantum cryptography protocols.
- Quantum computing: Entangled photons can be utilized for quantum computing operations, such as quantum gates and quantum algorithms.
Problems solved by this technology:
- Secure communication: The method enables the generation and distribution of entangled photon pairs, which can be used for secure communication, as any attempt to intercept or tamper with the photons would disrupt their entanglement.
- Quantum information processing: The entangled photon pairs can be used for various quantum information processing tasks, such as teleportation and quantum state transfer.
Benefits of this technology:
- Enhanced security: Entangled photons provide a high level of security in communication and cryptography, as any eavesdropping attempts would be detectable.
- Efficient quantum communication: The method allows for the efficient generation and distribution of entangled photon pairs, enabling faster and more reliable quantum communication.
- Scalability: The distributed nature of the system allows for scalability, as multiple remote nodes can be connected to a central entangling node, facilitating the expansion of the quantum-based communication network.
