\## ▍ What It Is



\*\*Dense Evolution\*\* is a high-performance statevector simulator engineered for deep NISQ circuits, VQE pipelines, and QML workloads. It eliminates Kronecker product overhead entirely via stride-sliced linear kernel fusion compiled through JAX XLA — keeping memory at the theoretical minimum of `2ⁿ × 16 bytes`.



The integrated `dash.py` dashboard provides live ipywidgets telemetry across 6 quantum observables per simulation run, directly inside Google Colab or Jupyter.

\---



\## ▍ VQE Engine



\*\*Positional parameter injection\*\* — `QASMParser` tokenizes all literals to `0.0` for JIT speed. VQE recovers parameters by:

1\. counting parametric gates (`rx ry rz p u1 cp crz`) → `n\_params`

2\. initializing `θ ∈ ℝⁿ` uniform in `\[−π, π]`

3\. injecting `θ\[i]` sequentially by gate order in the AST via `risolvi\_qasm()`



Compatible with any custom OpenQASM 2.0 string without pre-labelling.



\*\*Gradient \& update rule:\*\*



$$\\frac{\\partial E}{\\partial \\theta\_i} = \\langle\\psi(\\theta)|\\,\\frac{\\partial H}{\\partial \\theta\_i}\\,|\\psi(\\theta)\\rangle \\qquad \\theta \\leftarrow \\theta - \\frac{\\alpha\\,\\hat{m}\_t}{\\sqrt{\\hat{v}\_t}+\\varepsilon}$$



\*\*Telemetry columns\*\* (→ `df\_vqe\_telemetry`):



| Column | Unit | Description |

|---|---|---|

| `VQE\_Energy` | Ha | ⟨ψ\\|H\\|ψ⟩ |

| `Entropy` | bit | −Tr(ρ log₂ ρ) |

| `Purity` | — | Tr(ρ²) ∈ \[1/d, 1] |

| `Gradient` | — | ‖∇L‖ — barren plateau detection |

| `Noise\_Factor` | — | fidelity-derived noise proxy |

| `Theta\_Correction` | rad | ADAM step norm |



\---



\## ▍ Hamiltonian Library



Auto-filtered by qubit count to prevent shape mismatch.



| Molecule | Qubits | Bond length | E₀ (Ha) |

|---|:---:|:---:|:---:|

| H₂ | 2 | 0.74 Å | −1.13 |

| H₃⁺ | 3 | 0.85 Å | −1.28 |

| LiH | 4 | 1.40 Å | −2.31 |

| H₂O | 5 | 0.96 Å | −4.12 |



Custom: JSON array of diagonal eigenvalues, length `2^n\_qubits`.



\---



\## ▍ Noise Models



All channels applied as post-circuit Kraus operations on the full statevector.



| Model | Kraus operators | Physical process |

|---|---|---|

| `ideal` | I | noiseless |

| `depolarizing` | {√(1−p)I, √(p/3)X,Y,Z} | isotropic Pauli error |

| `amplitude\_damping` | {K₀, K₁} | T₁ energy relaxation |

| `phase\_damping` | {K₀, K₁} | T₂ dephasing |

| `bitflip` | {√(1−p)I, √p·X} | bit flip σₓ |

| `combined` | depolarizing(p/2) ∘ amp\_damp(p/3) | worst-case NISQ |



Fidelity: Bhattacharyya `F = Σᵢ √(pᵢqᵢ)` and TVD `= ½Σᵢ|pᵢ−qᵢ|` computed on every noisy run.



\---



\## ▍ Troubleshooting



| Error | Cause | Fix |

|---|---|---|

| `TypeError: cond branches must have equal output types` | JAX dtype mismatch between 1q/2q branches | `de.patch\_dense\_parametric(de.DenseSVSimulator)` — runs automatically on import |

| VQE telemetry empty | VQE disabled or no parametric gates | Enable \*\*VQE Settings\*\* checkbox; use circuits with `rx/ry/rz` gates |

| Hamiltonian shape mismatch | JSON array length ≠ 2^n\_qubits | Supply exactly `2^n` values (e.g. 16 for 4q) |

| Barren plateau span not visible | < 3 consecutive epochs with ‖g‖ < 0.01·max‖g‖ | Increase epochs or reduce learning rate |

| Dashboard blank in JupyterLab | Extension missing | `jupyter labextension install @jupyter-widgets/jupyterlab-manager` |

| Memory error on high-qubit circuits | 2ⁿ × 16 bytes: 24q = 268 MB, 30q = 16 GB | Use `use\_float32=True` to halve; cap at 24q on standard runtimes |
