quantum-computing

quantum-computing is a skill for Claude Code, Codex from beita6969/ScienceClaw. It costs 46 tokens per session (747 once invoked), scanned A, original, MIT.

A guide for designing and analyzing quantum-computing programs, which use quantum bits and operations instead of ordinary computer bits. It covers circuits, algorithms, error correction, and quantum hardware considerations.

In plain words
What is it for?
Use it to build quantum circuits, implement algorithms such as Shor's, Grover's, VQE, or QAOA, simulate circuits, and study error correction.
Why use it?
It helps translate a problem into a quantum-computing approach and assess whether a quantum method might offer an advantage. It also addresses noise and hardware limits.

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

quantum-computing 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 9d 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.

When to Trigger

Activate this skill when the user mentions:

  • Quantum circuits, quantum gates (Hadamard, CNOT, Toffoli)
  • Qubits, superposition, entanglement, measurement
  • Quantum algorithms (Shor's, Grover's, VQE, QAOA)
  • Quantum error correction, decoherence, noise models
  • Quantum advantage, quantum supremacy, complexity classes (BQP)
  • Quantum hardware (superconducting, trapped ion, photonic)
  • Quantum simulation, quantum chemistry applications

Step-by-Step Methodology

  1. Problem formulation - Determine if the problem has a known quantum advantage. Map the problem to a quantum computing framework: gate-based, adiabatic, or measurement-based. Identify required qubit count and circuit depth.
  2. Algorithm selection - For search: Grover's (quadratic speedup). For factoring: Shor's. For optimization: QAOA or quantum annealing. For chemistry: VQE or QPE. For machine learning: quantum kernels or variational classifiers.
  3. Circuit design - Construct the quantum circuit using elementary gates (H, CNOT, Rz, Ry). Decompose multi-qubit gates into native gate sets. Minimize circuit depth and CNOT count for near-term hardware compatibility.
  4. Simulation - Simulate circuit on classical hardware using Qiskit Aer, Cirq, or PennyLane. For small systems (<30 qubits), use statevector simulation. For larger systems, use tensor network or MPS methods.
  5. Noise analysis - Model realistic noise: single-qubit and two-qubit gate errors, measurement errors, T1/T2 decoherence times. Use noise models from real hardware backends (IBM Quantum, IonQ).
  6. Error mitigation / correction - For near-term (NISQ): zero-noise extrapolation, probabilistic error cancellation, dynamical decoupling. For fault-tolerant: surface codes, repetition codes, logical qubit encoding.
  7. Results analysis - Compare quantum vs. classical performance. Report circuit metrics (depth, gate count, qubit count). Assess scalability and resource requirements for practical problem sizes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

quantum-computing is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It adds 46 tokens to every session and 747 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
