qdash-two-qubit-calibration-diagnosis

qdash-two-qubit-calibration-diagnosis is a skill for Claude Code, Codex from oqtopus-team/qdash. It costs 60 tokens per session (891 once invoked), scanned A, original, Apache-2.0.

A diagnostic workflow for checking the quality of two-qubit calibration results. Two-qubit calibration tunes how a quantum computer operates a pair of qubits, and the workflow compares measurements such as gate and Bell-state fidelity.

In plain words
What is it for?
Use it to investigate poor coupling calibration, compare results across cooldowns, inspect prerequisites, and validate results without immediately rerunning tests or applying changes.
Why use it?
A calibration task finishing does not prove that the resulting gate is accurate, so this workflow examines evidence before suggesting action.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qdash-two-qubit-calibration-diagnosis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

QDash Two-Qubit Calibration Diagnosis

Use this skill when investigating coupling-level calibration quality, especially when tasks are completed but quality may be poor.

Principles

  • Treat completed as execution status, not proof of calibration quality.
  • Diagnose from evidence before suggesting operational actions.
  • Resolve cooldown membership before comparing calibrations or coherence limits. Keep different cooldowns separate, and distinguish a cooldown boundary from an in-cooldown wiring change.
  • Prefer read-only tools first: qdash_list_cooldowns, qdash_target_report, qdash_list_task_results, qdash_get_task_result, qdash_analyze_figure_json, and qdash_get_task_figures.
  • Do not rerun RB first when validation quality is suspicious. Walk back through prerequisites.
  • Do not commit or apply candidates without explicit user confirmation, and only after downstream validation.

Standard read-only investigation

For a coupling cA-B:

  1. Build context with qdash_list_cooldowns, qdash_target_report, and recent task results for the coupling. Record the cooldown ID for each result and inspect wiring events when measurement conditions may have changed.
  2. Inspect the latest same-cooldown tasks in this chain by default, and call qdash_get_task_knowledge for each task before interpreting its outputs or figures:
    • CheckCrossResonance
    • CreateZX90
    • CheckZX90
    • CheckBellState
    • CheckBellStateTomography
    • Check2QGateCoherenceLimit
    • ZX90InterleavedRandomizedBenchmarking
  3. Fetch task details and record:
    • CR: cr_amplitude, cr_phase, cancel_amplitude, cancel_phase, rotary_amplitude, zx_rotation_rate
    • ZX90: zx90_gate_time
    • Bell tomography: bell_state_fidelity
    • Coherence limit: two_qubit_gate_coherence_limit
    • IRB: zx90_gate_fidelity, its error, zx90_depolarizing_rate, n_trials
  4. For JSON figures, use qdash_analyze_figure_json before manually reading raw Plotly JSON.
  5. Summarize symptoms, likely failure mode, and the next read-only or confirmation-gated step.
