Popis: | The Bloch sphere provides an elegant way of visualizing a qubit. Analogous representation of the simplest composite state of two-qubits has attracted significant attention. Here we present a detailed mathematical analysis of the real-matrix parametrization and associated geometric picturization of arbitrary two-qubit states - up to their local SL2C equivalence, in terms of canonical ellipsoids inscribed within the Bloch sphere. Comment: 12 pages, 8 figures, one table; typos in Example 2 corrected; Submitted to "Bound States and Quantum Correlations - ARP Rau special collection" |
