Absolute frequency measurement of the $^{40}$ Ca $^{+}$ clock transition using a GNSS link to the SI second

M. Guevara-Bertsch, M. K. Joshi, M. I Hussain +2

We report the absolute frequency measurement of the $4 s$ $^{2} S_{1/2} \leftrightarrow 3 d$ $^{2} D_{5/2}$ $^{40}$ Ca $^{+}$ clock transition with respect to the SI second. To perform t…

Local robust shadows on a trapped ion computer -- a case study

Jadwiga Wilkens, Milena Guevara-Bertsch, Marwa Marso +6

We experimentally demonstrate local robust shadows on a trapped-ion quantum computing system, a protocol developed to counteract measurement errors. We alternate between a calibrat…
