Laser linewidth effects in quantum state discrimination by electromagnetically induced transparency

Abstract:
The use of electromagnetically modified absorption to achieve selective excitation in atoms was discussed. It was found that the selectivity is limited by the decoherence rate of the dark state. Exact analytical expressions and physical models for this effect were presented. Results show that when the laser frequencies are near-resonant, coherent population trapping (CPT) is essential for achieving discrimination.
