Abstract: | A scheme is proposed for generating two-mode SU(2) and SU(1,1) cat states for an ion trapped in a two-dimensional (2D) anisotropic
harmonic potential trap. In the scheme the ion is excited by two laser beams in the trap plane. After an interaction time,
a measurement on the internal state collapses the ion motion onto a superposition of two SU(2) or SU(1,1) coherent states
depending on the laser frequencies.
