Comparison, optimization, and application of various spontaneous parametric downconversion sources of polarization-entangled photon pairs
… technology makes it possible to create bright entangled-photon sources that can be used on platforms where weight and stability requirements are limiting factors, e.g., on aerial or even space-based mobile platforms, which could allow reconfigurable long-distance transfer of photonic qubits. …

Tools for quantum optics : pulsed polarization-maintaining Er-doped fiber laser and spatial mode manipulation in spontaneous parametric downconversion
… were undertaken to improve technology for entangled photon sources, useful for quantum optics. In one project, a pulsed, mode-locked erbium-doped fiber laser, designed to be used as a seed laser for a 390 nm source, was built using polarization-maintaining components to address polarization …

Nonlinear Periodic Structures: From Classical to Quantum Devices
… for the first time, through this process, entangled photon pairs are generated. Unprecedented performance, in terms of brightness and purity, of III-V semiconductor-based entangled photon sources has been demonstrated here. Moreover, the quantum properties of these entangled photons are …

Quantum Cryptography: From Theory to Practice
… QKD experiments. A weak coherent state has multi-photon components, which opens up a security loophole to the sophisticated eavesdropper. With a small adjustment of the hardware, we will prove that the decoy state method can close this loophole and substantially improve the QKD performance. We …

Semiconductor-generated entangled photons for hybrid quantum networks
… in the deterministic generation of single photons and polarization entangled photon pairs are semiconductor InAs/GaAs quantum dots grown by the Stranski-Krastanov method. Despite remarkable progress in the last twenty years, complex quantum optical protocols could not be realized due to low …

Growth, characterization and implementation of semiconductor sources of highly entangled photons
Sources of single and polarization-entangled photons are an essential component in a variety of potential quantum information applications. Suitable emitters need to generate photons deterministically and at fast repetition rates, with highest degrees of single-photon purity, entanglement and …

Investigating exciton correlations using coherent multidimensional optical spectroscopy
… complexes. Because future technologies such as entangled photon sources, advanced photovoltaics, and quantum information processing will rely on these types of materials and their many-body correlations, it is important to develop techniques to measure their microscopic interactions directly.
