  • Large-scale atom interferometers enable precise measurements of fundamental constants and novel sensors. This study uses Floquet formalism to create an optimal transported state, resulting in an efficient large-momentum-transfer interferometer, advancing largescale interferometers.

  • A system in equilibrium takes a finite time to relax to a new equilibrium following a sudden change of a control parameter—impeding progress in device miniaturization. Now, a strategy succeeds in reducing this time for an open classical system.

  • Transforming a quantum system with high fidelity is usually a trade-off between an increase in speed—thereby minimizing decoherence—and robustness against fluctuating control parameters. Protocols at these two extreme limits are now demonstrated and compared using Bose–Einstein condensates in optical traps.

  • Matter-wave sensors benefit from high flux cold atomic sources. Here, a time-averaged optical dipole trap is reported that generates Bose-Einstein condensates by fast evaporative cooling and further reduces the expansion by means of an all-optical matter-wave lens.
