Hyperfine qubit coherence in a tweezer array

Hyperfine qubit coherence in a tweezer array in the Records: every value read on the maker's own pages, with its day.

In inglese

Measure: Coherence time — arxiv.org, read 16 October 2026
Value: 12.6 seconds — arxiv.org, read 16 October 2026
Reported: 18 March 2024 — arxiv.org, read 16 October 2026
Method: Not confirmed: two readings disagree: XY16 dynamical decoupling of hyperfine qubits in optical tweezers and By applying cycles of XY16 sequences with a period of 12.5 ms between π pulses, the measured dephasing time is T2 = 12.6(1) s, a new benchmark for the coherence time of an array of hyperfine qubits in optical tweezers
