HERALDED PHOTONIC ENTANGLEMENT SOURCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240295792 titled 'HERALDED PHOTONIC ENTANGLEMENT SOURCE

The patent application describes a method for generating entangled optical outputs using heralded entanglement sources.

  • First and second free-running entanglement sources provide optical outputs with quantum superpositions of orthogonal optical modes.
  • An optical module performs interferometric measurements based on optical interference between the outputs to generate detection signals.
  • A trigger module generates a trigger signal based on the detection signals to indicate entanglement between the optical outputs in specific time slots.

Potential Applications: - Quantum communication - Quantum cryptography - Quantum computing

Problems Solved: - Generation of entangled optical outputs - Reliable detection of entanglement

Benefits: - Enhanced security in communication - Improved quantum computing capabilities

Commercial Applications: Title: Quantum Communication Systems This technology can be used in developing secure communication systems for government and financial institutions, as well as in advancing quantum computing research.

Questions about Entangled Optical Outputs: 1. How does the interferometric measurement process work in generating detection signals?

  The interferometric measurement process involves analyzing the optical interference between the outputs to determine the entanglement between them.

2. What are the practical implications of entangled optical outputs in quantum communication?

  Entangled optical outputs can enable secure communication channels that are resistant to eavesdropping due to the quantum properties of entanglement.


Original Abstract Submitted

entangled optical outputs are generated using one or more heralded entanglement sources, each comprising: first and second free-running entanglement sources, each providing a first (third) optical output comprising a quantum superposition of a pair of orthogonal optical modes, and a second (fourth) optical output comprising a quantum superposition of a pair of orthogonal optical modes; an optical module configured to perform an interferometric measurement based on optical interference between at least a portion of the first optical output and at least a portion of the third optical output, and to generate one or more detection signals based on the interferometric measurement in a series of time slots; and a trigger module configured to generate a trigger signal based on the one or more detection signals to indicate one or more time slots in which the second optical output and the fourth optical output are entangled with each other.
