Understanding EIP Protocols

Understanding EIP Protocols

EIP (Entanglement Interface Protocol) defines standardized methods for quantum operations in the LUXBIN network.

EIP-001: NV-Center Quantum Memory

Purpose: Store quantum states in diamond nitrogen-vacancy centers

Key Features

  • Room temperature operation
  • Long coherence times (milliseconds to seconds)
  • Optical interface for photonic qubits
  • Nuclear spin for extended storage

    • Operations

  • Initialize: Optical pumping to |0⟩ state
  • Manipulate: Microwave pulses for gates
  • Readout: Fluorescence measurement
  • Transfer: Optical coupling to photon

    EIP-002: Bell Pair Generation

    Purpose: Create maximally entangled photon pairs

    The Bell States

    |Φ+⟩ = (|00⟩ + |11⟩)/√2   "Both same"
|Φ-⟩ = (|00⟩ - |11⟩)/√2   "Both same, phase"
|Ψ+⟩ = (|01⟩ + |10⟩)/√2   "Both different"
|Ψ-⟩ = (|01⟩ - |10⟩)/√2   "Both different, phase"

    Generation Method

    Spontaneous Parametric Down-Conversion (SPDC) in BBO crystals

    EIP-003: GHZ State Networks

    Purpose: Multi-party entanglement distribution

    The GHZ State

    |GHZ⟩ = (|000...0⟩ + |111...1⟩)/√2

    Applications

  • Multi-party secret sharing
  • Quantum voting protocols
  • Distributed sensing

    EIP-004: Quantum Teleportation

    Purpose: Transfer quantum states between nodes

    The Protocol

  • Share entangled Bell pair
  • Bell measurement at sender
  • Classical communication of results
  • Correction at receiver

    • Key Property

    The original quantum state is destroyed at the sender and recreated at the receiver - information is teleported, not copied.
