Skill Codex
A Chinese-language skill for checking configured quantum-computing providers and finding available hardware through FieldQKit. It only supports read-only credential checks and backend discovery.
Skill Claude CodeCodex
A read-only diagnostic procedure for checking whether an OpenQuantum platform's user interface, task runner, skills, and models are connected correctly. It produces a report with evidence for each check.
Skill Codex
A local simulation workflow for testing error correction in a small surface-code quantum memory. It adds a defined error rate, samples measurement results, and uses a matching decoder to estimate logical errors.
Skill Codex
A local workbench for reading, converting, analysing, and translating OpenQASM 3 and QPY quantum circuits. QPY is Qiskit's binary circuit format, while OpenQASM 3 is a text format.
Skill Codex
A workflow for turning small binary optimisation problems into QUBO models. QUBO represents choices as zero-or-one variables and uses a formula to score each combination.
Skill Codex
A local checker for deciding whether two small OpenQASM 2 quantum circuits perform the same quantum transformation. OpenQASM 2 is a text format for describing quantum circuits.
Skill Codex
A narrowly defined quantum solver for the ground-state energy of a two-quantum-bit Pauli Hamiltonian in a specified one-excitation sector. It uses a noiseless statevector VQE and checks the result against an exact calculation; VQE is a method that searches for a low-energy quantum state.
Skill Codex
A local audit tool for density matrices, which are tables describing quantum states that may include uncertainty or mixtures. It checks mathematical properties such as trace, Hermiticity, positive semidefiniteness, purity, partial-transpose eigenvalues, and negativity.
Skill Codex
A guide for choosing software tools for quantum-computing projects. It matches the problem, hardware goal, programming language, cost, licence, and verification needs to a recommended software stack.
Skill Codex
A guided local simulator for small quantum circuits. It runs circuits with up to eight quantum bits and can compare exact results with sampled results that include several noise types.
Skill Codex
A local simulator for superconducting quantum-bit experiments, including measurements used to study and tune a qubit. It produces bounded synthetic results without connecting to laboratory hardware or quantum cloud services.
Skill Codex
A quantum-computing experiment guide that uses a local tool to simulate small circuits and physical hardware models. It covers superconducting devices, atom arrays, transmon leakage, and Rydberg-atom dynamics.
Skill Claude CodeCodex
A small quantum-optimization experiment that trains parameters for a low-energy state of a user-provided Hamiltonian, a mathematical description of a quantum system's energy. It supports 2–4 qubits and compares the trained result with an exact energy and a random baseline.
Skill Claude CodeCodex
A binary error-correction decoder that uses a parity-check matrix and measured error syndromes. It returns a correction, the remaining syndrome, and whether the parity checks are satisfied.
Skill Claude CodeCodex
A small quantum-state measurement tool that estimates the purity of a selected group of qubits using random measurements, then compares the estimate with an exact value. It supports 2–6 qubits and product or GHZ states.
Skill Claude CodeCodex
A small quantum-chemistry calculation for an H2 molecule using the STO-3G basis, a simplified representation of atomic orbitals. It samples a reduced space, estimates its energy, and compares it with full configuration interaction, an exact calculation within the same small model.
Skill Claude CodeCodex
A finite spin-chain ground-state solver using DMRG, an algorithm that approximates low-energy states by limiting the amount of information kept between sites. It compares the result with exact diagonalization for small systems.
Skill Claude CodeCodex
A simulation of an open quantum spin chain using random quantum-jump trajectories, compared with a density-matrix evolution. An open system is one that can exchange information or energy with its surroundings.
Skill Claude CodeCodex
A local sampler for Clifford+T quantum circuits with a specified single-qubit depolarizing error after each gate. It returns final computational-basis samples and can compare them with an independent density-matrix calculation.
Skill Claude CodeCodex
A local experiment builder for rectangular rotated planar quantum error-correction codes. It creates noisy circuits, samples them, and decodes the results to report logical failures for X or Z memory experiments.
Skill Claude CodeCodex
A local simulation for the time evolution of a driven, damped single qubit. It calculates population paths and how the final population changes as the drive changes, with optional independent and finite-difference comparisons.
Skill Claude CodeCodex
A local tool that converts supported quantum circuits into measurement-based quantum computing (MBQC) patterns and simulates their adaptive measurements. It returns the resource graph, measurement and correction commands, and optional comparison with a direct state-vector simulation.
Skill Claude CodeCodex
A local experiment runner for testing four ways to reduce errors in sampled quantum circuits: zero-noise extrapolation, readout correction, probabilistic error cancellation, and Clifford data regression. It compares noisy and mitigated results under the same sampling budget.
Skill Claude CodeCodex
A local simulation of a two-level quantum system coupled to an environment with memory. It uses the TEMPO method to calculate non-Markovian dynamics, meaning the environment can affect the system based on its earlier state.
