Quantum gates using electronic and nuclear spins of Yb$^{+}$ in a magnetic field gradient

, 2011
An efficient scheme is proposed to carry out gate operations on an array of trapped Yb$^+$ ions, based on a previous proposal using both electronic and nuclear degrees of freedom in a magnetic field gradient. For this purpose we consider the Paschen-Back

Synthetic Antiferromagnetic Designer Nanodisks for High‐Performance Magnetic Separation

Advanced Healthcare Materials, Volume 14, Issue 31, December 8, 2025.
Micromagnetic‐modeling‐based design and scalable fabrication of synthetic antiferromagnet (SAF) magnetic disk particles (MDPs) using sputter deposition enable high‐performance magnetic separation. The SAF MDPs achieve high colloidal stability and magnetic responsiveness and enable efficient magnetic separation, outperforming conventional particles ...

Anomalous Dynamics of Superparamagnetic Colloidal Microrobots with Tailored Statistics

Small, Volume 21, Issue 47, November 27, 2025.
Superparamagnetic microrobots are demonstrated to navigate with advanced stochastic motion strategies, producing the entire spectrum of anomalous diffusion, from subdiffusion to superdiffusion, over at least two decades in space and time. Abstract Living organisms have developed advanced motion strategies for efficient space exploration, serving as ...
