Package landing page for The Quaternionic Wavefunction: Spin-1/2 Particles, S^3, and SU(2). This package is intended as a conceptual prequel to the rest of the quaternionic quantum computing series.
This prequel introduces the quaternionic wavefunction as an expository bridge from a two-component spinor in C^2 to the geometry of S^3 and the transformation group SU(2), with an emphasis on spin-1/2 particles and the 4 pi property.
