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…
Entanglement detection via mutually unbiased bases
Christoph Spengler, Marcus Huber, Stephen Brierley +2
We investigate correlations among complementary observables. In particular, we show how to take advantage of mutually unbiased bases (MUBs) for the efficient detection of entanglem…
Quantifying entanglement of maximal dimension in bipartite mixed states
Gael SentÃs, Christopher Eltschka, Otfried Gühne +2
The Schmidt coefficients capture all entanglement properties of a pure bipartite state and therefore determine its usefulness for quantum information processing. While the quantifi…
Measurements in two bases are sufficient for certifying high-dimensional entanglement
Jessica Bavaresco, Natalia Herrera Valencia, Claude Klöckl +5
High-dimensional encoding of quantum information provides a promising method of transcending current limitations in quantum communication. One of the central challenges in the purs…
The thermodynamics of creating correlations: Limitations and optimal protocols
David Edward Bruschi, Martà Perarnau-Llobet, Nicolai Friis +2
We establish a rigorous connection between fundamental resource theories at the quantum scale. Correlations and entanglement constitute indispensable resources for numerous quantum…
Realising a quantum absorption refrigerator with an atom-cavity system
Mark T. Mitchison, Marcus Huber, Javier Prior +2
An autonomous quantum thermal machine comprising a trapped atom or ion placed inside an optical cavity is proposed and analysed. Such a machine can operate as a heat engine whose w…
