Harnessing high-dimensional temporal entanglement using limited interferometric setups
Alexandra Bergmayr, Florian Kanitschar, Matej Pivoluska +1
High-dimensional entanglement has shown to have significant advantages in quantum communication. It is available in many degrees of freedom and in particular in the time-domain rou…
Key Issues Review: Useful autonomous quantum machines
José Antonio Marín Guzmán, Paul Erker, Simone Gasparinetti +2
Controlled quantum machines have matured significantly. A natural next step is to increasingly grant them autonomy, freeing them from time-dependent external control. For example,…
Resource-efficient high-dimensional entanglement detection via symmetric projections
Simon Morelli, Marcus Huber, Armin Tavakoli
We introduce two families of criteria for detecting and quantifying the entanglement of a bipartite quantum state of arbitrary local dimension. The first is based on measurements i…
Photonic entanglement during a zero-g flight
Julius Bittermann, Lukas Bulla, Sebastian Ecker +6
Quantum technologies have matured to the point that we can test fundamental quantum phenomena under extreme conditions. Specifically, entanglement, a cornerstone of modern quantum…
Correlation constraints and the Bloch geometry of two qubits
Simon Morelli, Christopher Eltschka, Marcus Huber +1
We present a novel inequality on the purity of a bipartite state depending solely on the difference of the local Bloch vector lengths. For two qubits this inequality is tight for a…
Quantum measurements and equilibration: the emergence of objective outcomes via entropy maximisation
Emanuel Schwarzhans, Felix C. Binder, Marcus Huber +1
The measurement postulate of quantum theory stands in conflict with the laws of thermodynamics and has evoked debate regarding what actually constitutes a measurement. With the hel…
