Regina Kruse successfully defended her Ph.D. thesis "One, Two, Many Modes: Development & Application of High-Dimensional Systems for Quantum Information Science".
Jano Gil López defended his master's thesis titled "Tailoring spatial modes for sum-frequency generation in lithium niobate waveguides". He will pursue his Ph.D in the IQO Group at Paderborn University.
The Integrated Quantum Optics group sent a large contingent to this year’s DPG spring meeting of the Atomic, Molecular, Plasma Physics and Quantum Optics Section (SAMOP) in Mainz. Eight PhD students, five Master students, one postdoc, and one junior professor attended.
Prof. Dr. Christine Silberhorn konnten kürzlich erstmals Bandbreitenkompression für Einzelphotonen mit hocheffizienter Frequenzkonversion kombinieren. Die Versuchsanordnung basiert auf nichtlinearen Wellenleitern in Lithiumniobat, die die Gruppe selbst in Paderbornb herstellt. Die spektralen Eigenschaften von Einzelphotonenquellen im Telecom-Band können damit besser als zuvor an die von atomaren Systemen im sichtbaren und nah-infraroten…
The characterization of quantum states is an essential part of quantum optics. One particular task is the estimation of squeezing in so called two-mode squeezed states.
In a recent publication in Physical Review Letters*, researchers from the integrated quantum optics group in Paderborn in collaboration with theoretical physicists from Olomouc in the Czech Republic and Madrid in Spain have demonstrated a method to measure such squeezing in a…
The generation of macroscopic quantum states is a challenging goal throughout many fields of physics. Not only would it be fascinating to see quantum effects on a macroscopic scale, their generation is also a prerequisite if one wants to exploit quantum effects for real-world applications.
In a joint publication, recently published in Physical Review Letters*, scientists from two groups at the University of Paderborn, the IQO and the MQO, in…

The aim for understanding transport phenomena is at the heart of many studies on processes in nature and man-made structures ranging from photosynthesis to information network applications. Recent research indicates that the combination of classical with quantum effects can explain or introduce highly unexpected behaviour of the overall system. In order to understand quantum transport processes on a random or…
Rebeccah Grotemeyer defended her bachelor's thesis with the title "Comparison of classically excited modes and modes excited through parametric down-conversion".
