Article Synopsis
- Many experimental setups in quantum science rely on laser fields for controlling states, but this control can suffer from issues related to optical phase noise.
- Researchers introduced an optical feedforward technique to minimize laser phase noise during the stimulated Raman adiabatic passage for transferring ultracold RbCs molecules.
- After conducting over 100 transfers on individual molecules, they achieved a notable transfer efficiency of 98.7(1)%, which is primarily constrained by the intensity of the lasers used.
We demonstrate Rydberg blockade due to the charge-dipole interaction between a single Rb atom and a single RbCs molecule confined in optical tweezers. The molecule is formed by magnetoassociation of a Rb+Cs atom pair and subsequently transferred to the rovibrational ground state with an efficiency of 91(1)%. Species-specific tweezers are used to control the separation between the atom and molecule.

Both atoms are initially predominantly in the motional ground states of their respective tweezers. We confirm molecule formation and establish the state of the molecule formed by measuring its binding energy.

Throughout aquatic environments, highly mobile predators are thought to serve as important vectors of energy between ecosystems thereby promoting stability and resilience. However, the role these predators play in connecting food webs and promoting energy flow remains poorly understood in most contexts.
