Quantum measurements and new concepts for experiments with trapped ions
Christof Wunderlich, Christoph Balzer
Experiments with individual trapped ions are ideally suited to investigate fundamental issues of quantum mechanics such as the measurement process. At the same time electrodynamica…

Conditional Spin Resonance with Trapped Ions
Christof Wunderlich
Internal states of different ions in an electrodynamic trap are coupled when a static magnetic field is applied -- analogous to spin-spin coupling in molecules used for NMR. This s…

Estimation of qubit states in a factorizing basis
Th. Hannemann, D. Reiss, Ch. Balzer +3
The optimal estimation of a quantum mechanical 2-state system (qubit) - with N identically prepared qubits available - is obtained by measuring all qubits simultaneously in an enta…
