On some 2D orthogonal q-polynomials
Mourad E. H. Ismail, Ruiming Zhang
We introduce two q-analogues of the 2D-Hermite polynomials which are functions of two complex variables. We derive explicit formulas, orthogonality relations, raising and lowering…

Lazy states, discordant states and entangled states for 2-qubit systems
Jianwei Xu
We investigate the lazy states, entangled states and discordant states for 2-qubit systems. We show that many lazy states are discordant, many lazy states are entangled, and many m…
