Manipulating sudden death of entanglement of two-qubit X-states in thermal reservoirs
Mazhar Ali, G. Alber, A. R. P. Rau
Manipulation of sudden death of entanglement (ESD) of two qubits interacting with statistically uncorrelated thermal reservoirs is investigated. It is shown that for initially prep…

Two-qubit analogs of octonions and projective planes
A. R. P. Rau
A quantum spin-1/2, and its associated su(2) algebra of Pauli spin matrices are familiarly linked to Clifford algebra and quaternions. Somewhat more loosely, we develop connections…

Geometric phases and Bloch sphere constructions for SU(N), with a complete description of SU(4)
D. Uskov, A. R. P. Rau
A two-sphere ("Bloch" or "Poincare") is familiar for describing the dynamics of a spin-1/2 particle or light polarization. Analogous objects are derived for unitary groups larger t…
