GHZ protocols enhance frequency metrology despite spontaneous decay
Timm Kielinski, Piet O. Schmidt, Klemens Hammerer
The use of correlated states and measurements promises improvements in the accuracy of frequency metrology and the stability of atomic clocks. However, developing strategies robust…
Multi-ion frequency reference using dynamical decoupling
Lennart Pelzer, Kai Dietze, Víctor J. Martínez-Lahuerta +6
We present the experimental realization of a continuous dynamical decoupling scheme which suppresses leading frequency shifts in a multi-ion frequency reference based on $^{40}\mat…
Quadrupole transitions and quantum gates protected by continuous dynamic decoupling
V. J. Martínez-Lahuerta, L. Pelzer, K. Dietze +3
Dynamical decoupling techniques are a versatile tool for engineering quantum states with tailored properties. In trapped ions, nested layers of continuous dynamical decoupling by m…
