Theory for the Beam Splitter in Quantum Optics: Quantum Entanglement of Photons and Their Statistics, HOM Effect

open access: yesMathematics, 2022
The theory of the beam splitter (BS) in quantum optics is well developed and based on fairly simple mathematical and physical foundations. This theory has been developed for any type of BS and is based on the constancy of the reflection coefficients R ...

Generating quantum entangled photons

open access: yes, 2021
In this project a laser setup was constructed, quantum entangled photons were generated and two different methods were used to show said entanglement. The entangled photons were generated through a process called spontaneous parametric down conversion ...

Multimode quantum states with single photons carrying orbital angular momentum

open access: yes, 2017
We propose and experimentally demonstrate a scheme for generating multimode quantum states with single photons carrying orbital angular momentum (OAM). Various quantum states have been realized by superposing multiple OAM modes of single photons in two ...

Tunneling times of single photons [PDF]

open access: yes, 2021
Although the group delay of classical pulses through a barrier may suggest superluminality, the information transfer is limited by the precursor which propagates at the vacuum light speed. Single photons, however, have infinite tails, and the question of

Quantum science in a nutshell: fostering students' functional understanding of models

open access: yesFrontiers in Education, 2023
Fostering students' understanding of models is a challenge. However, in particular for learning quantum physics an elaborate understanding of models is required. We investigated activities to foster students' functional thinking about (quantum) models in
