Description

Precise molecular orientation is crucial for optimizing chemical reaction efficiency and enabling distortion-free measurements in the molecular frame [1,2]. We propose using Quantum Optimal Control theory to orient any molecular axes along any laboratory direction, extending previous results on ground-state molecular rotational states [3,4]. Specifically, we focus on highly rotating molecular states, known as superrotors. These states exhibit stable alignment on a plane due to centrifugal forces, making them promising candidates for precise control of the non-aligned molecular axis.

Beyond controlling molecular orientation, we extend our framework to manipulate spin states [5] in molecular spin chains, providing a versatile tool for quantum information processing and transport.
