Scrutinizing single-qubit quantum channels: Theory and experiment with trapped ions
Thilo Hannemann, Christof Wunderlich, Martin Plesch +2
We report experimental implementation of various types of qubit channels using an individual trapped ion. We analyzed experimental data and we performed tomographic reconstruction…
Electrodynamically trapped Yb+ ions for quantum information processing
Chr. Balzer, A. Braun, T. Hannemann +4
Highly efficient, nearly deterministic, and isotope selective generation of Yb ions by 1- and 2-color photoionization is demonstrated. State preparation and state selective det…
Robust state preparation of a single trapped ion by adiabatic passage
Chr. Wunderlich, Th. Hannemann, T. Koerber +5
We report adiabatic passage experiments with a single trapped Ca ion. By applying a frequency chirped laser pulse with a Gaussian amplitude envelope we reach a transfer…
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…
