2-qubit states, visualized 8 ways
One entangled state, eight ways to see it. Onri Jay Benally's runnable notebook renders a 2-qubit state as Bloch spheres, Q-spheres, steering ellipsoids, Wigner functions, and more.
Krylov Quantum Diagonalization of Lattice Hamiltonians
Implement the Krylov Quantum Diagonalization Algorithm (KQD) within the context of Qiskit patterns.
Rabi Oscillations: Visualizing Excited-State Probability
A primer on the quantum dynamics of a driven two-level system, visualizing excited-state probability under the rotating-wave approximation (RWA).
