Universal Gate Operations on Nuclear Spin Qubits in an Optical Tweezer Array of Yb 171 Atoms
Open accessAbstract
Neutral atom arrays are a rapidly developing platform for quantum science.Recently, alkaline earth atoms (AEAs) have attracted interest because their unique level structure provides several opportunities for improved performance.In this work, we present the first demonstration of a universal set of quantum gate operations on a nuclear spin qubit in an AEA, using 171 Yb.We implement narrow-line cooling and imaging using a newly discovered magic trapping wavelength at λ ¼ 486.78 nm.We also demonstrate nuclear spin initialization, readout, and single-qubit gates and observe long coherence times [T 1 ≈ 20 s and24ð5Þ s] and a single-qubit operation fidelity F 1Q ¼ 0.99959ð6Þ.We also demonstrate two-qubit entangling gates using the Rydberg blockade, as well as coherent control of these gate operations using light shifts on the Yb þ ion core transition at 369 nm.These results are a significant step toward highly coherent quantum gates in AEA tweezer arrays.

Schemes for near-deterministic loading of optical tweezers have been realised in research labs, to overcome the stochastic nature of the trap loading and to finally supersede the rearrangement process.

Relatively long coherence times, especially for approaches using nuclear spin qubits such as Strontium or Ytterbium, compensate for the slower gate operations.
“However, this is compensated by the relatively long coherence times, especially for approaches using nuclear spin qubits such as in Strontium or Ytterbium [72,73].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
