Query: Implementation of Quantum Logic Gates Using Polar Molecules in Pendular
  States   We present a systematic approach to implementation of basic quantum logic
gates operating on polar molecules in pendular states as qubits for a quantum
computer. A static electric field prevents quenching of the dipole moments by
rotation, thereby creating the pendular states; also, the field gradient
enables distinguishing among qubit sites. Multi-Target Optimal Control Theory
(MTOCT) is used as a means of optimizing the initial-to-target transition
probability via a laser field. We give detailed calculations for the SrO
molecule, a favorite candidate for proposed quantum computers. Our simulation
results indicate that NOT, Hadamard and CNOT gates can be realized with high
fidelity for such pendular qubit states.
