## 📊 Core Concepts

### 1. Quantum State Teleportation

Transfer arbitrary quantum state |ψ⟩ from sender to receiver using shared entanglement:

#### Standard Protocol
- **Resource**: Shared Bell pair |Φ⁺⟩ = (|00⟩ + |11⟩)/√2
- **Measurement**: Bell state measurement on sender's qubits
- **Communication**: 2 classical bits indicating BSM result
- **Correction**: Receiver applies unitary based on classical bits
- **Fidelity**: F = (2F_ent + 1)/3 for imperfect entanglement

#### Bell States
```
|Φ⁺⟩ = (|00⟩ + |11⟩)/√2  →  I (identity)
|Φ⁻⟩ = (|00⟩ - |11⟩)/√2  →  Z
|Ψ⁺⟩ = (|01⟩ + |10⟩)/√2  →  X
|Ψ⁻⟩ = (|01⟩ - |10⟩)/√2  →  XZ
```

### 2. Bell State Measurement

High-fidelity measurement techniques:

#### Linear Optics BSM
- Success probability: 50% (2 of 4 Bell states distinguishable)
- Photonic implementation using beam splitters and detectors
- Non-destructive measurement options

#### Complete BSM
- Ion traps: Near-unity success probability
- Superconducting qubits: High-fidelity projective measurement
- NV centers: Optical addressing with spin readout

### 3. Teleportation Network Architecture

Multi-node teleportation systems:
- Point-to-point teleportation links
- Quantum repeater chains for long distance
- Teleportation routing protocols
- Entanglement distribution networks
- Resource allocation strategies
