SU(2) geometry

SU(2) is the group structure behind single-qubit unitary rotations and is central to RQM's geometric foundations.

---

Definition

A matrix U is in SU(2) when:

U†U = I
 det(U) = 1

---

Practical takeaway

RQM uses the SU(2)-quaternion relation in rqm-core to keep optimization and analysis grounded in consistent geometry.
