Experimental Quantum State Tomography of a Solid State Qubit
Andreas Walther, Lars Rippe, Brian Julsgaard, Stefan Kröll · International Conference on Quantum Information · 2008
An ensemble of Pr3+ ions is prepared inside a zero-absorption spectral hole, to act as a qubit. Quantum state tomography with robust pulses, to compensate for inhomogeneities, is demonstrated with >90% fidelity.
