Rydberg atom entanglements in the weak coupling regime
Hanlae Jo, Yunheung Song, Minhyuk Kim +1
We present an entanglement scheme for Rydberg atoms using the van der Waals interaction phase induced by Ramsey-type pulsed interactions. This scheme realizes not only controlled p…
Coherent and dissipative dynamics of entangled few-body systems of Rydberg atoms
Woojun Lee, Minhyuk Kim, Hanlae Jo +2
Experimentally observed quantum few-body dynamics of neutral atoms excited to a Rydberg state are numerically analyzed with Lindblad master equation formalism. For this, up to five…
Leakage suppression by ultrafast pulse shaping
Hanlae Jo, Yunheung Song, Jaewook Ahn
We consider the leakage suppression problem of a three-level system in which the first two levels are the qubit system and the third, weakly-coupled to the second, is the leakage s…
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…
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…
Selective excitation in a three-state system using a hybrid adiabatic-nonadiabatic interaction
Yunheung Song, Han-gyeol Lee, Hanlae Jo +1
The chirped-pulse interaction in the adiabatic coupling regime induces cyclic permutations of the energy states of a three-level system in the -type configuration, which process…
In situ single-atom array synthesis by dynamic holographic optical tweezers
Hyosub Kim, Woojun Lee, Han-gyeol Lee +3
Cooling and trapping of atoms by light has enabled one to build and manipulate quantum systems at the single atom level. Such a bottom-up approach becomes one of the fascinating ch…
Quantum dynamics of a two-state system induced by a chirped zero-area pulse
Han-gyeol Lee, Yunheung Song, Hyosub Kim +2
It is well known that area pulses make Rabi oscillation and chirped pulses in the adiabatic interaction regime induce complete population inversion of a two-state system. Here we s…
