Tuner Archive

Build a one-page web app called "Tuner Archive" for photographers, photo editors, photojournalists.

Headline: Optimize a style parameter ansatz against photographers's photojournalism archives goal and return tuning knobs that actually converge.

CONSTRAINTS (read first):
- I am on Lovable's FREE plan with ~5 credits. Build this in ONE message. Do NOT add features beyond what is listed.
- No accounts, no Lovable Cloud, no database, no auth. Static app only.
- One page: a workspace. Plus a small "About the quantum" strip at the bottom.

REAL QUANTUM (Quantinuum Guppy + Selene) — run AT BUILD TIME in the Lovable Linux sandbox, not at runtime:
1. In the sandbox, run:  pip install guppylang selene-sim
2. Create quantum/kernel.py containing a VQE-style parameterized circuit optimized against a style cost Hamiltonian, returning the optimal parameter vector. It MUST be a real .py file on disk (Guppy reads source via inspect.getsource — REPL/exec strings fail).
3. Create quantum/run.py that imports the @guppy kernel, compiles it, and runs it on the Selene emulator (≤8 qubits, 256 shots) over 8 style targets × 30 optimizer steps = 8 parameter vectors + cost curves. Write the real results to src/data/quantum-results.json with shape: an array of { input, output } records where output contains optimal parameters + final cost.
4. Execute quantum/run.py ONCE during the build so src/data/quantum-results.json is committed real Selene output. Do not call Python at runtime — Cloudflare Workers cannot run Python.

FRONTEND (TanStack Start, single route /):
- Import src/data/quantum-results.json statically.
- Workspace UI: left = input picker tied to the precomputed grid (photojournalism archives); center = live visual built from the selected record; right = a slider panel where each slider is one optimized parameter, plus a 'cost over iterations' chart driven by the JSON.
- "Quantum trace" disclosure: show the raw optimal parameters + final cost for the active record and a "View Guppy source" toggle that prints the contents of quantum/kernel.py inline, so judges see this is genuine Variational ansatz on Selene, not a fake.
- Design: dark workspace, ONE accent color matched to the Photography mood, ONE typeface family, tactile micro-interaction when the user picks a new record.

Deliverable: a single deploy where every number on screen traces back to a real Selene shot from quantum/kernel.py. Ship in one message.

--- QUANTINUUM APPENDIX (self-contained reference — paste verbatim) ---
[1] INSTALL (Lovable Linux sandbox):
  python -m pip install --no-cache-dir guppylang selene-sim

[2] IMPORTS (use exactly these — no other quantum libs):
  # quantum/kernel.py and quantum/run.py top
  from guppylang import guppy
  from guppylang.std.builtins import result
  from guppylang.std.quantum import qubit, h, cx, rx, ry, rz, measure, discard, t as tgate, tdg
  from guppylang.std.angles import angle, pi
  from selene_sim import build, Quest
  import math, json, sys, tempfile, importlib.util, uuid
  from pathlib import Path

[3] HARD RULES (violating any breaks the build):
  - @guppy reads source via inspect.getsource → kernels MUST live in a real .py file on disk. No exec(), no REPL strings, no inline templates.
  - Allowed gate set ONLY: h, rx, ry, rz, cx, tgate, tdg. There is NO native ccx/toffoli, cswap, cphase, or crz — decompose using the snippets in [7].
  - Qubit ownership: a qubit passed to a function is moved. You MUST measure() or discard() every qubit exactly once; never reuse after measure.
  - Angle hygiene before baking a float into generated source:
        theta = ((theta + math.pi) % (2.0 * math.pi)) - math.pi
    and write it with repr: f"... {theta!r} ..."  (str(float) can truncate).

[4] SELENE SHOT LOOP (canonical):
  compiled = my_kernel.compile()
  runner   = build(compiled)
  shots = []
  for shot in runner.run_shots(Quest(), n_qubits=N, n_shots=S):
      shots.append({str(lbl): int(v) for lbl, v in shot})
  # N = MAX number of qubits simultaneously LIVE in the kernel.
  # measure(q) releases the slot, so one ancilla reused across k windows still counts as 1.

[5] DRIVER PATTERN — sweep a kernel over many inputs (closures do NOT work):
  ROOT = Path(__file__).resolve().parent.parent
  if str(ROOT) not in sys.path: sys.path.insert(0, str(ROOT))

  def run_one(params: dict, shots: int = 256):
      # Bake params as literals into a fresh .py file that imports your kernel helpers.
      src = (
          "from quantum.kernel import guppy, my_helper\n"
          "@guppy\n"
          "def program() -> None:\n"
          f"    my_helper({params['a']!r}, {params['b']!r})\n"
      )
      tmp = Path(tempfile.gettempdir()) / "qprogs"; tmp.mkdir(exist_ok=True)
      name = f"prog_{uuid.uuid4().hex[:8]}"
      path = tmp / f"{name}.py"; path.write_text(src)
      spec = importlib.util.spec_from_file_location(name, path)
      mod  = importlib.util.module_from_spec(spec)
      sys.modules[name] = mod                       # register BEFORE exec_module
      spec.loader.exec_module(mod)
      runner = build(mod.program.compile())
      out = []
      for shot in runner.run_shots(Quest(), n_qubits=5, n_shots=shots):
          out.append({str(l): int(v) for l, v in shot})
      return out

[6] PER-QUBIT INTEGER DECODE (host-side):
  # kernel emits: for j in range(n): result(f"x{j}", measure(q[j]))
  def decode(rec, n):
      x = 0
      for j in range(n): x |= (rec.get(f"x{j}", 0) & 1) << j
      return x

[7] DECOMPOSITION LIBRARY (copy verbatim into quantum/kernel.py):

  # ---- Toffoli (CCX) from H, CX, T, Tdg — 6-T standard decomposition ----
  @guppy
  def toffoli(c1: qubit, c2: qubit, tgt: qubit) -> None:
      h(tgt)
      cx(c2, tgt); tdg(tgt)
      cx(c1, tgt); tgate(tgt)
      cx(c2, tgt); tdg(tgt)
      cx(c1, tgt); tgate(c2); tgate(tgt)
      h(tgt)
      cx(c1, c2); tgate(c1); tdg(c2)
      cx(c1, c2)

  # ---- CSWAP (Fredkin) from CX + Toffoli ----
  @guppy
  def cswap(c: qubit, a: qubit, b: qubit) -> None:
      cx(b, a)
      toffoli(c, a, b)
      cx(b, a)

  # ---- Controlled phase exp(i*theta) on |11> from rz + cx ----
  @guppy
  def cphase(c: qubit, d: qubit, theta: float) -> None:

  def prep_features(q0: qubit, q1: qubit, a: float, b: float, c: float) -> None:
      ry(q0, angle(a))
      ry(q1, angle(b))
      cx(q0, q1)
      rz(q1, angle(c))

  # ---- SWAP test kernel; HOST inverts:  F = clamp(2*P(anc=0) - 1, 0, 1) ----
  @guppy
  def swap_test(ai: float, bi: float, ci: float,
                aj: float, bj: float, cj: float) -> None:
      anc = qubit()
      pi0 = qubit(); pi1 = qubit()
      pj0 = qubit(); pj1 = qubit()
      prep_features(pi0, pi1, ai, bi, ci)
      prep_features(pj0, pj1, aj, bj, cj)
      h(anc)
      cswap(anc, pi0, pj0)
      cswap(anc, pi1, pj1)
      h(anc)
      result("anc", measure(anc))
      discard(pi0); discard(pi1); discard(pj0); discard(pj1)
  # n_qubits = 5 for swap_test above.

[8] CLASSICAL CROSS-CHECK (NumPy reference — commit alongside quantum result):
  import numpy as np
  I = np.eye(2); X = np.array([[0,1],[1,0]])
  def RY(t): c,s = math.cos(t/2), math.sin(t/2); return np.array([[c,-s],[s,c]])
  def RZ(t): return np.array([[np.exp(-1j*t/2),0],[0,np.exp(1j*t/2)]])
  CX = np.array([[1,0,0,0],[0,1,0,0],[0,0,0,1],[0,0,1,0]])
  def prep_psi(a,b,c):
      s = np.kron(RY(a)@np.array([1,0]), RY(b)@np.array([1,0]))
      s = CX @ s
      s = np.kron(I, RZ(c)) @ s
      return s
  def classical_fidelity(p, q):
      return float(abs(np.vdot(prep_psi(*p), prep_psi(*q)))**2)
  # Commit BOTH quantum and classical values per record:
  #   {"input": [...], "quantum": 0.873, "classical": 0.881, "shots": 256}

[9] FRONTEND HANDOFF (TanStack Start):
  # quantum/run.py last step:
  Path("src/data/quantum-results.json").write_text(json.dumps({
      "records": records,                          # list of {input, quantum, classical, ...}
      "circuit": {"n_qubits": 5, "shots": 256},
      "kernel_source": Path("quantum/kernel.py").read_text(),  # show on /code tab
  }, indent=2))
  # In React:  import data from "@/data/quantum-results.json"  (resolveJsonModule:true).
  # Render data.records; render data.kernel_source in a <pre> inside the Quantum trace tab.

[10] BUILD ORDER (do not deviate — keeps you under 5 credits):
  1. Write quantum/kernel.py with the helpers from [7] you actually need.
  2. Write quantum/run.py: driver pattern from [5], Selene loop from [4], cross-check from [8], JSON write from [9].
  3. Execute once:  python quantum/run.py   (commit src/data/quantum-results.json).
  4. Build the React route: static JSON import, shadcn Card + Tabs + Slider + Badge wiring.
  5. Deploy. No Python at runtime; every on-screen number traces to committed Selene output.

[11] OUTPUT CONTRACT — selene_run v1 (write this exact shape to src/data/quantum-results.json):
  {
    "schemaVersion": 1,
    "experiment": "<idea-slug>",
    "title": "<idea title>",
    "description": "<one plain-English sentence — what a non-quantum dev sees>",
    "kernel": { "snippet": "<first 40 lines of quantum/kernel.py>", "qubits": <int>, "shotsPerRow": <int> },
    "verdict": { "text": "<one-sentence headline of the result>", "good": true },
    "metrics": [ { "name": "<label>", "value": <number>, "unit": "<%|bits|Hz|...>", "good": true } ],
    "series":  [ { "id": "<id>", "kind": "histogram"|"bar"|"line", "title": "...",
                   "xLabel": "...", "yLabel": "...", "yKeys": ["count"],
                   "points": [ { "label": "<x>", "values": { "count": <num> } } ] } ]
  }
  Reason: one schema = one renderer = a polished demo without bespoke React per idea.
  All metric / series VALUES must come from real Selene shot data committed in step 3 — no mocks.

[12] RENDERER — create src/components/SeleneRunView.tsx with EXACTLY this body (no deps beyond react + tailwind):

  import * as React from "react";
  type Point  = { label: string; values: Record<string, number> };
  type Series = { id: string; kind: "histogram"|"bar"|"line"; title: string;

  type Metric = { name: string; value: number; unit?: string; good?: boolean };
  export type SeleneRun = {
    schemaVersion: 1; experiment: string; title: string; description: string;

[HOOK] VQE — variational energy minimization.
  Ansatz kernel takes a θ-vector baked via the driver pattern in [5]:
    for j: ry(q[j], angle(theta[j])); then cx ladder; repeat L layers.
  Measure Pauli terms shot-by-shot:  <Z_j> = (#0 - #1)/S;  <X_j> with an extra h(q[j]) before measure.
  <H>(θ) = Σ_i w_i * <P_i>(θ).
  Optimizer: coarse host-side grid (e.g. 8 values × 2 params = 64 runs). No SciPy needed.
