Subpicosecond rotations of atomic clock states
Yunheung Song, Han-gyeol Lee, Hyosub Kim +2
We demonstrate subpicosecond-time-scale population transfer between the pair of hyperfine ground states of atomic rubidium using a single laser-pulse. Our scheme utilizes the geome…
Single-laser-pulse implementation of arbitrary ZYZ rotations of an atomic qubit
Han-gyeol Lee, Yunheung Song, Jaewook Ahn
Arbitrary rotation of a qubit can be performed with a three-pulse sequence; for example, ZYZ rotations. However, this requires precise control of the relative phase and timing betw…
Robust two-level system control by a detuned and chirped laser pulse
Hanlae Jo, Han-gyeol Lee, Stephane Guerin +1
We propose and demonstrate a robust control scheme by ultrafast nonadiabatic chirped laser pulse, designed for targeting coherent superpositions of two-level systems. Robustness ag…
