Fault-tolerant quantum computation with a neutral atom processor
Ben W. Reichardt, Adam Paetznick, David Aasen +69
Quantum computing experiments are transitioning from running on physical qubits to using encoded, logical qubits. Fault-tolerant computation can identify and correct errors, and ha…
One second interrogation time in a 200 round-trip waveguide atom interferometer
Hyosub Kim, Katarzyna Krzyzanowska, K. C. Henderson +3
We report a multiple-loop guided atom interferometer in which the atoms make 200 small-amplitude roundtrips, instead of one large single orbit. The approach is enabled by using ult…
Detailed Balance of Thermalization dynamics in Rydberg atom quantum simulators
Hyosub Kim, Yeje Park, Kyungtae Kim +2
Dynamics of large complex systems, such as relaxation towards equilibrium in classical statistical mechanics, often obeys a master equation. The equation significantly simplifies t…
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…
Defect-free atomic array formation using Hungarian matching algorithm
Woojun Lee, Hyosub Kim, Jaewook Ahn
Deterministic loading of single atoms onto arbitrary two-dimensional lattice points has recently been demonstrated, where by dynamically controlling the optical-dipole potential, a…
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…
Rabi oscillations of Morris-Shore transformed -state systems by elliptically polarized ultrafast laser pulses
Hyosub Kim, Yunheung Song, Han-gyeol Lee +1
We present an experimental investigation of ultrafast-laser driven Rabi oscillations of atomic rubidium. Since the broadband spectrum of an ultrafast laser pulse simultaneously cou…
Coherent Control of Resonant Two-Photon Transitions by Counter-Propagating Ultrashort Pulse Pairs
Woojun Lee, Hyosub Kim, Kyungtae Kim +1
We describe optimized coherent control methods for two-photon transitions in atoms of a ladder-type three-state energy configuration. Our approach is based on the spatial coherent…
Ultrafast Rabi oscillation of a Gaussian atom ensemble
Han-gyeol Lee, Hyosub Kim, Jaewook Ahn
We investigate Rabi oscillation of an atom ensemble in Gaussian spatial distribution. By using the ultrafast laser interaction with the cold atomic rubidium vapor spatially confine…
