Feasibility studies for quantum computation with spectral hole burning media
… quantum bits (qubits) are stored in individual spectral holes of an in homogeneously broadened medium, such as a cryogenically cooled crystal of Pr:Y2 SiO 3 . Qubits are transferred between spectral holes by virtue of mutual coupling of the atoms to a single quantized cavity mode, which allows …

Slow and fast light by spectral hole-burning in the solid state
… and superluminal light, especially the spectral hole-burning technique are reviewed and applied in the experiments. The experimental studies conducted are based on transient and persistent spectral hole-burning and the solid state materials emerald (Be₃Al₂Si₆O₁₈:Cr³⁺), ruby (Al₂O₃:Cr³⁺) …

Viscoelastic and nanomechanical behaviors of polymeric materials
… In this work, the strain-controlled mechanical spectral hole burning (Strain_MSHB) technique is successfully expanded to stress-controlled (Stress_MSHB) fashion. The dynamic heterogeneity of a polymer solution probed with both MSHB techniques are compared. In addition, the local temperature …

COHERENCE AND FREQUENCY STABILITY OF SEMICONDUCTOR LASERS UNDER CW OPERA TI ON AND MODULATION
… used in similar analyses. The results of spectral hole burning arising from long scattering times with corresponding detrimental effects on modal stability are presented. With further incorporation of a nonlinear gain suppression term arising from population beating (due to coupling of the …

Ultrasound-encoded optical tomography and time-reversed ultrasonically encoded optical focusing
… of ultrasound-tagged photons. We also applied spectral-hole burning: SHB) aided detection in ultrasound-modulated optical tomography: UOT) to image optical heterogeneities in thick tissue-mimicking phantom samples and chicken breast tissue. The efficiency of SHB was improved by using a Tm3+: …

Spectroscopic Investigations of Light-Harvesting 2 Complexes from Rps. acidophila
… complexes concerning the correlation between spectral positions and widths (full width at half maximum, FWHM) was found. This strongly implied the existence of a different electron-phonon coupling strength for each complex, and moreover, led to the conclusion that at least for some of the …

Coherent Processes in Rare-Earth-Ion-Doped Solids
… that come from performing the storage inside spectrally structured materials, were investigated. In order to carry out the phase-sensitive experiments, a laser system with a very narrow linewidth of ~1 kHz at 606 nm was constructed, by locking the laser to a semi-persistent spectral hole. In …

Quantum computing with naturally trapped sub-nanometre-spaced ions
… absorbing on a single transition, residing in spectral pits with no other ions, have been isolated. It is shown how these ions can be coherently transferred between hyperfine levels via the optically excited state, how the interaction between such peaks of ions representing qubits can be turned …
