Majorana Zero Modes in a Topological Nanowire

This simulator renders the Kitaev chain — the canonical minimal model of a topological superconducting nanowire — as a 3D lattice of paired Majorana fermions. Each physical site splits into two Majorana operators; sliders for chemical potential μ, pairing Δ and hopping t set exactly how those operators pair up, and the 3D bond brightness shows that pairing directly: short on-site bonds in the trivial phase, long inter-site bonds in the topological phase, leaving one Majorana unpaired at each end of the wire. Live readouts track the bulk excitation gap, the end-mode localization length, and the topological winding invariant, and a parity-measurement button demonstrates how the two end modes encode one non-local, noise-resistant topological qubit.
