Quantum Control in the Cs 6S_{1/2} Ground Manifold Using rf and μw Magnetic Fields
arXiv:1308.4731 · doi:10.1103/PhysRevLett.111.170502
Abstract
We implement arbitrary maps between pure states in the 16-dimensional Hilbert space associated with the ground electronic manifold of Cs. This is accomplished by driving atoms with phase modulated rf and μw fields, using modulation waveforms found via numerical optimization and designed to work robustly in the presence of imperfections. We evaluate the performance of a sample of randomly chosen state maps by randomized benchmarking, obtaining an average fidelity >99%. Our protocol advances state-of-the-art quantum control and has immediate applications in quantum metrology and tomography.
