Entanglement Harvesting from Electromagnetic Quantum Fields
Frieder Lindel, Alexa Herter, Valentin Gebhart +2
In many states of the quantum electromagnetic field, including the vacuum state, entanglement exists between different space-time regions -- even space-like separated ones. These c…

Creating nonlocality using geometric phases between partially distinguishable photons
Valentin Gebhart
The geometric (Berry-Pancharatnam) phase originates from the intrinsic geometry of the space of quantum states and can be observed in different situations, such as a cyclic evoluti…
