Abstract
Time-frequency resolved coherent anti-Stokes Raman scattering (TFRCARS) was recently proposed as a means to
implement quantum logic using the molecular ro-vibrational manifold as a quantum register [R. Zadoyan et al., Chem.
Phys. 266 (2001) 323]. We give a concrete example of how this can be accomplished through an illustrative algorithm
that solves the Deutsch­Jozsa (DJ) problem. We use realistic molecular parameters to recognize that, as the problem
size expands, shaped pulses must be tailored to maintain fidelity of the algorithm. Ó 2002 Published by Elsevier
