Laser stabilization using spectral hole burning
L. Rippe, B. Julsgaard, A. Walther +1
We have frequency stabilized a Coherent CR699-21 dye laser to a transient spectral hole on the 606 nm transition in Pr^{+3}:Y_2SiO_5. A frequency stability of 1 kHz has been obtain…
Micro-cavity length stabilization for fluorescence enhancement using schemes based on higher order spatial modes
A. Shehata Abdelatief, A. J. Renders, M. Alqedra +4
We report on experimental investigation of potential high-performance cavity length stabilization using odd-indexed higher-order spatial modes. Schemes based on higher-order modes…
Experimental quantum state tomography of a solid state qubit
L. Rippe, B. Julsgaard, A. Walther +2
Full quantum state tomography is used to characterize the state of an ensemble based qubit implemented through two hyperfine levels in Pr3+ ions, doped into a Y2SiO5 crystal. We ex…
High fidelity readout scheme for rare-earth solid state quantum computing
A. Walther, L. Rippe, Y. Yan +5
We propose and analyze a high fidelity readout scheme for a single instance approach to quantum computing in rare-earth-ion-doped crystals. The scheme is based on using different s…
Extracting high fidelity quantum computer hardware from random systems
A. Walther, B. Julsgaard, L. Rippe +4
An overview of current status and prospects of the development of quantum computer hardware based on inorganic crystals doped with rare-earth ions is presented. Major parts of the…
