Quantum Optics and Quantum Information Processing in Rare-Earth-Ion-Doped Crystals
… between light and the ions in the crystals. A photon echo experiment has been performed where faint optical pulses were accumulated in the crystal. In this experiment, the possibility of single photons acting as two of the optical fields in the photon echo process was investigated. Different …

Quantum-classical correspondence in response theory
… part of thesis the effect of quantum chaos on photon echo-signal of two-electronic state molecular systems is studied. The temporal photon echo signal is shown to reveal key information about the nuclear dynamics in the excited electronic state surface.

Coherent Interactions in Rare-Earth-Ion-Doped Crystals for Applications in Quantum Information Science
… the quantum state of light in a solid, using photon-echo-like techniques, is proposed and analysed. In the proposed scheme, an optical wave packet is absorbed and subsequently re-emitted by an inhomogeneous absorption profile, which is tailored and externally controlled by the application of …

Vibrational Relaxation and Vibrational Cooling in Molecular Crystals
… (durene, naphthalene) is studied with the ps photon echo technique. The results obtained by echoes on vibrations in the electronically excited state are compared to previous ps time delayed coherent Raman studies of ground state vibrations of the pure host matrix. The relaxation channels for …

Generation of high power single-cycle and multiple-cycle terahertz pulses
… spectroscopy in the THz region such as the photon echo and multidimensional spectroscopy, revealing novel phenomena in solids, liquids, gases, and complex materials.

Two-dimensional Spectroscopy of Molecular Excitons in a Model Dimer System
… recent studies using electronic two-dimensional photon-echo spectroscopy (2DPE), particularly in the context of light harvesting in photosynthesis. Since the spectra for multichromophoric aggregates are congested, particularly so at room temperature, we present a study of a model dimer comprised …

Controlling and probing nonlinear collective mode dynamics in quantum materials
… multiferroic are revealed through terahertz photon echo measurements. Together, these results highlight how tailored light-matter interactions can be leveraged to probe, control, and manipulate material degrees of freedom, both in and out of equilibrium.

Coherent Processes in Rare-Earth-Ion-Doped Solids
… a variety of methods, including among others, photon echo techniques and electromagnetically induced transparency. Quantum computing is a rapidly growing field and there are still many potential candidates for its implementation. In our work we have utilized the spin states of the Pr rare-earth …

Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme
… experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion) can be used as a local probe to sense the quantum state of a neighbouring single-ion qubit via a state-selective …
