Direct measurement of isotope shifts in the barium 6s S-5d6p D transition
Jungwoo Choi, Eunhwi Lee, Dahyun Yum +2
We report the direct measurement of isotope shifts of the barium 6s S --5d6p D 413-nm electric quadrupole transition, which is utilized for efficient b…
Realization of two-dimensional crystal of ions in a monolithic Paul trap
Ye Wang, Mu Qiao, Zhengyang Cai +9
We present a simple Paul trap that stably accommodates up to a couple of dozens of \ensuremath{^{171}\mathrm{Yb}^+~} ions in a stationary two-dimensional lattice. The trap is const…
Single atom energy-conversion device with a quantum load
Noah Van Horne, Dahyun Yum, Tarun Dutta +4
This work reports the functioning of a single atom energy-conversion device, operating either as a quantum engine or a refrigerator, coupled to a quantum load. The "working fluid"…
Single-qubit quantum memory exceeding -minute coherence time
Ye Wang, Mark Um, Junhua Zhang +6
A long-time quantum memory capable of storing and measuring quantum information at the single-qubit level is an essential ingredient for practical quantum computation and com-munic…
Optical Barium Ion Qubit
Dahyun Yum, Debashis De Munshi, Tarun Dutta +1
We demonstrate an optical single qubit based on 6S1/2 to 5D5/2 quadrupole transition of a single Ba+ ion operated by diode based lasers only. The resonance wavelength of the 6S1/2…
An exacting transition probability measurement - a direct test of atomic many-body theories
T. Dutta, D. De Munshi, D. Yum +2
A new protocol for measuring the branching fraction of hydrogenic atoms with only statistically limited uncertainty is proposed and demonstrated for the decay of the P leve…
