# Q-TensorFormer: Quantum-Enhanced Tensor Network LLM Compression Engine
|
| 14 |
|
| 15 |
+
## Overview
|
|
|
|
| 16 |
|
| 17 |
+
**Q-TensorFormer** is a hybrid quantum-tensor model that adaptively compresses itself using entanglement entropy, achieving major efficiency gains with minimal performance loss.
|
| 18 |
|
| 19 |
+
**Claim**: 50-70% parameter reduction with same accuracy ± small drop, fewer compute ops / latency.
|
| 20 |
+
|
| 21 |
+
## Architecture
|
| 22 |
+
|
| 23 |
+
### Three Pillars
|
| 24 |
+
|
| 25 |
+
1. **Tensor Compression (Efficiency)**
|
| 26 |
+
- Dense FFN layers replaced with Tensor-Train (TT) decomposition via tltorch
|
| 27 |
+
- Dramatic parameter reduction while preserving expressivity
|
| 28 |
+
|
| 29 |
+
2. **Quantum Feature Encoding (Expressivity)**
|
| 30 |
+
- PennyLane quantum circuits encode token embeddings into quantum states
|
| 31 |
+
- Angle encoding + variational circuits extract richer features than classical
|
| 32 |
+
|
| 33 |
+
3. **Entanglement-Guided Rank Adaptation (Novelty)**
|
| 34 |
+
- `r = r_min + α · S(ρ)` — tensor ranks adjust based on quantum state entropy
|
| 35 |
+
- Model becomes input-aware and compute-efficient
|
| 36 |
+
|
| 37 |
+
### Core Components
|
| 38 |
+
|
| 39 |
+
- `TTFactorizedLinear`: Tensor-Train compressed linear layers
|
| 40 |
+
- `QuantumFeatureEncoder`: PennyLane angle encoding with TorchLayer
|
| 41 |
+
- `QuantumKernelAttention`: Quantum kernel self-attention (QKSAN-style)
|
| 42 |
+
- `SelectiveQuantumRouter`: Only "hard" tokens go to quantum circuit
|
| 43 |
+
- `RankScheduler`: Entanglement-guided dynamic rank adjustment
|
| 44 |
+
|
| 45 |
+
