Spatial adiabatic passage (SAP) is a process that facilitates the transfer of wavepackets between two local modes that are not directly coupled and interact through an intermediate third mode. This technique employs a counterintuitive adiabatic pulse sequence to minimize the intermediate state population and achieve high transfer efficiency. Here we report an implementation of SAP for transferring giant particles between three micro-optical traps. First, he prepares a cryogenic fermionic atom in a low-vibrational eigenstate of one trap, then he manipulates the distance between the three traps to run the SAP protocol. It was observed that the atoms moved smoothly between the two outer traps and the number of atoms in the central trap was low. We validate our findings and emphasize the importance of the counterintuitive sequence by reversing the order of the pulse sequence. In addition, we investigate the effects of the tunneling speed and the time delay between the movement of the two external tweezers on the fidelity of the process. Our results open up new possibilities for advanced control and manipulation schemes in optical tweezer array platforms.
