Seconds-scale coherence on an optical clock transition in a tweezer array

MA Norcia, AW Young, WJ Eckner, E Oelker, J Ye… - Science, 2019 - science.org
Coherent control of high–quality factor optical transitions in atoms has revolutionized
precision frequency metrology. Leading optical atomic clocks rely on the interrogation of …

An atomic-array optical clock with single-atom readout

IS Madjarov, A Cooper, AL Shaw, JP Covey… - Physical Review X, 2019 - APS
Currently, the most accurate and stable clocks use optical interrogation of either a single ion
or an ensemble of neutral atoms confined in an optical lattice. Here, we demonstrate a new …

Quantum logic and entanglement by neutral Rydberg atoms: methods and fidelity

XF Shi - Quantum Science and Technology, 2022 - iopscience.iop.org
Quantum gates and entanglement based on dipole–dipole interactions of neutral Rydberg
atoms are relevant to both fundamental physics and quantum information science. The …

2000-times repeated imaging of strontium atoms in clock-magic tweezer arrays

JP Covey, IS Madjarov, A Cooper, M Endres - Physical review letters, 2019 - APS
We demonstrate single-atom resolved imaging with a survival probability of 0.99932 (8) and
a fidelity of 0.99991 (1), enabling us to perform repeated high-fidelity imaging of single …

Analyzing the Rydberg-based optical-metastable-ground architecture for nuclear spins

N Chen, L Li, W Huie, M Zhao, I Vetter, CH Greene… - Physical Review A, 2022 - APS
Neutral alkaline earth (like) atoms have recently been employed in atomic arrays with
individual readout, control, and high-fidelity Rydberg-mediated entanglement. This …

Absence of mobility edge in short-range uncorrelated disordered model: Coexistence of localized and extended states

AK Das, A Ghosh, IM Khaymovich - Physical Review Letters, 2023 - APS
Unlike the well-known Mott's argument that extended and localized states should not coexist
at the same energy in a generic random potential, we formulate the main principles and …

Dissipative Bose-Hubbard system with intrinsic two-body loss

T Tomita, S Nakajima, Y Takasu, Y Takahashi - Physical Review A, 2019 - APS
