Select an experiment below to launch its simulation and record your observations. Refer to the printed lab manual for background theory, pre-lab preparation, procedure, and analysis questions.
Operators, Eigenstates & Measurement
Build quantum superpositions, observe Born-rule collapses, and evaluate commutators on a particle in an infinite square well.
Wave–Particle Duality & Double Slit
Fire photons or electrons one at a time and watch a quantum interference pattern emerge on a virtual screen.
Spin-½ Measurement Statistics
Measure spin-½ outcomes versus angle and observe how an intervening measurement scrambles the quantum state.
Infinite Square Well
Explore exact energy levels, wavefunctions, node counts, and time-evolved superpositions of a particle-in-a-box.
Finite Square Well
Investigate numerically computed bound states and wavefunction penetration into classically forbidden regions.
Quantum Harmonic Oscillator
Verify the evenly-spaced energy spectrum and Hermite-polynomial wavefunctions for various particles and stiffnesses.
Free-Particle Wave Packets
Watch an exact Gaussian wave packet propagate and spread, and measure group velocity versus phase velocity.
Quantum Tunneling & Resonances
Measure exact transmission through a rectangular barrier and locate above-barrier transmission resonances.
Angular Momentum
Visualise the vector-cone model, explore quantum number constraints, and practice angular momentum addition rules.
