Protecting conditional quantum gates by robust dynamical decoupling
Ch. Piltz, B. Scharfenberger, A. Khromova +2
Dephasing -- phase randomization of a quantum superposition state -- is a major obstacle for the realization of high fidelity quantum logic operations. Here, we implement a two-qub…

Designer Spin Pseudomolecule Implemented with Trapped Ions in a Magnetic Gradient
A. Khromova, Ch. Piltz, B. Scharfenberger +4
We report on the experimental investigation of an individual pseudomolecule using trapped ions with adjustable magnetically induced J-type coupling between spin states. Resonances…
