Simultaneous cooling of axial vibrational modes in a linear ion-trap
Christof Wunderlich, Giovanna Morigi, Dirk Reiss
In order to use a collection of trapped ions for experiments where a well defined preparation of vibrational states is necessary, all vibrational modes have to be cooled to ensure…
A relaxationless demonstration of the Quantum Zeno Paradox on an individual atom
Chr. Balzer, Th. Hannemann, D. Reiß +3
The driven evolution of the spin of an individual atomic ion on the ground-state hyperfine resonance is impeded by the observation of the ion in one of the pertaining eigenstates.…
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…
From Spectral Relaxation to Quantified Decoherence
Chr. Balzer, Th. Hannemann, D. Reiß +3
Quantum information processing (QIP) requires thorough assessment of decoherence. Atoms or ions prepared for QIP often become addressed by radiation within schemes of alternating m…
Raman cooling and heating of two trapped Ba+ ions
D. Reiss, K. Abich, W. Neuhauser +2
We study cooling of the collective vibrational motion of two 138Ba+ ions confined in an electrodynamic trap and irradiated with laser light close to the resonances S_1/2-P_1/2 (493…
