Hands on Quantum Computer
summary
Builds a working Variational Quantum Eigensolver that finds the minimal eigenvalue of a 4x4 Hermitian matrix (two qubits) and matches the classical result (-3.08) by optimizing 16 gate parameters. Uses a browser-based quantum-circuit designer, exports runnable Python/Jupyter code for Qiskit + IBM Q backend, simulates state-vector results locally, and explains sampling/tomography limits on real devices. Materials and the exportable Jupyter notebook are provided; real-device runs hit cloud queue issues. VQE on 2 qubits
