Anticrossing-mediated entanglement of adsorbed polar molecules

Abstract: We study the entanglement of two adsorbed polar molecules in static electric fields. The concurrence is estimated to quantify the entanglement. The adsorbed molecules reveal significant rotational characteristics, such as anticrossing features, due to the influences of electric field and quantum confinement. Numerical results demonstrate that these rotational properties dominate the amount and profile of concurrence. At zero temperature, an enhanced concurrence is obtained near the anticrossing in the ground s… Show more
