3D Numerical Simulations of BEC Transport Using Shortcuts to Adiabaticity

We report on our numerical simulations of high-fidelity, fast quantum control of Bose-Einstein condensates (BECs) as we extend them to full 3D simulations. We simulate a 3D painted potential that provides complete confinement of the atoms. Painted potentials also allow for arbitrary and dynamic traps, which control the spatial transport of the BEC. To maintain high fidelity after transport, we implement shortcuts-to-adiabaticity (STAs) to design the BEC trajectory in our simulations. STAs allow fast movement while suppressing excitations that can result due to the rapid transitions of the quantum state. In our 3D simulations, quantum fidelities resulting from different, experimentally viable transport times and trap-depths are compared.
