A local Qiskit workflow for amplitude estimation, a quantum method for estimating the size or probability of a selected outcome. It can explain the method, build a circuit, or run a simulator calculation.
Skill Claude CodeCodex
An adiabatic quantum method for solving a positive-definite Hermitian system of linear equations. It gradually changes one system into another and approximates the solution through segmented quantum evolution.

A local implementation of a Cartan decomposition for real symmetric Hamiltonian matrices. A Hamiltonian is a matrix describing a system's energy or time evolution; the implementation uses SciPy's Schur decomposition to split it into useful parts.

A two-mode continuous-variable quantum neural network with layers for displacement, squeezing, rotation, Kerr effects, and beam splitting. Continuous-variable systems represent information with quantities such as light-field amplitudes rather than only bits.

A local quantum implementation of the discrete logarithm problem: finding an exponent in a modular power relationship. It uses a reversible oracle, Fourier sampling over a cyclic group, and congruences to recover the exponent.

A variational quantum simulation of the open-boundary Fermi–Hubbard chain, a model of particles hopping between sites and interacting when they occupy the same system. It maps the model to qubits with the Jordan–Wigner transformation and searches for a low-energy state.

A Qiskit method for estimating gradients with central finite differences. It changes a parameter slightly in both directions and uses the two results to approximate how an observable changes.

A simulation of quantum walking through glued trees: two trees joined by randomly alternating connections between their leaves. A continuous-time quantum walk evolves according to the graph's adjacency matrix.
