Deterministic quantum state transfer of atoms in a random magnetic field
We propose a method for transferring atoms to a target quantum state for a
multilevel quantum system with sequentially increasing, but otherwise unknown,
energy splitting. This is achieved with a feedback algorithm that processes
off-resonant optical measurements of state populations during adiabatic rapid
passage in real-time. Specifically, we reliably perform the transfer
for a
sample of ultracold Rb in the presence of a random external magnetic
field
