Trapped-Ion Qubits Simulator

Interactive 3D linear Paul trap: watch ions form a Coulomb crystal in the RF pseudopotential, tune ion count and confinement strength, and excite a shared phonon mode to see phonon-mediated qubit coupling.

ControlsIon chain length slider (2-10) sets how many ions are loaded into the trap; confinement strength slider (0.4-2.5) tunes the axial DC trap stiffness and reshapes the equilibrium Coulomb-crystal spacing; Excite phonon mode button kicks the chain into a decaying collective centre-of-mass vibration and shows the coupling laser bridging the outer ions; Reset restores defaults.

This simulator visualizes a linear Paul trap: four RF rod electrodes generate an oscillating field whose time-average forms a radial pseudopotential well, while static end-cap electrodes confine ions along the trap axis. Ions loaded into the trap repel each other via the Coulomb force and settle into an evenly-spaced linear chain — a Coulomb crystal. Adjust the ion count and confinement strength to see the equilibrium spacing shift, and excite the shared phonon mode to see the collective vibration that trapped-ion quantum computers use to couple distant qubits together.

⚙ Under the hood

Interactive 3D linear Paul trap: four RF rod electrodes form a radial pseudopotential while DC end-caps confine ions axially, so a loaded ion chain self-organizes into a Coulomb crystal. Adjust ion count and confinement strength to see the equilibrium spacing shift, and excite the shared phonon mode to visualize phonon-mediated qubit coupling (the Molmer-Sorensen gate mechanism).
