Retrievability of information in quantum and realistic hidden variable theories
Roope Uola, Erkka Haapasalo, Juha-Pekka Pellonpää +1
We propose a generalisation of the Leggett-Garg conditions for macrorealistic behaviour. Our proposal relies on relaxing the postulate of non-invasive measurability with that of re…
Naimark dilations of qubit POVMs and joint measurements
Juha-Pekka Pellonpää, Sébastien Designolle, Roope Uola
Measurement incompatibility is one of the cornerstones of quantum theory. This phenomenon appears in many forms, of which the concept of non-joint measurability has received consid…
Equivalence between simulability of high-dimensional measurements and high-dimensional steering
Benjamin D. M. Jones, Roope Uola, Thomas Cope +4
The effect of quantum steering arises from the judicious combination of an entangled state with a set of incompatible measurements. Recently, it was shown that this form of quantum…
Quantifying the high-dimensionality of quantum devices
Thomas Cope, Roope Uola
We introduce a measure of average dimensionality (or coherence) for high-dimensional quantum devices. This includes sets of quantum measurements, steering assemblages, and quantum…
Simulability of high-dimensional quantum measurements
Marie Ioannou, Pavel Sekatski, Sébastien Designolle +3
We investigate the compression of quantum information with respect to a given set of high-dimensional measurements. This leads to a notion of simulability, where we d…
Noise-Robust and Loss-Tolerant Quantum Steering with Qudits
Vatshal Srivastav, Natalia Herrera Valencia, Will McCutcheon +5
A primary requirement for a robust and unconditionally secure quantum network is the establishment of quantum nonlocal correlations over a realistic channel. While loophole-free te…
