Assisted Macroscopic Quantumness
Farid Shahandeh, Martin Ringbauer, Massimiliano Proietti +8
It is commonly expected that quantum theory is universal, in that it describes the world at all scales. Yet, quantum effects at the macroscopic scale continue to elude our experime…
A Unifying Framework for Spatial and Temporal Quantum Correlations
Fabio Costa, Martin Ringbauer, Michael E. Goggin +2
Measurements on a single quantum system at different times reveal rich non-classical correlations similar to those observed in spatially separated multi-partite systems. Here we in…
Genuinely Multipartite Noncausality
Alastair A. Abbott, Julian Wechs, Fabio Costa +1
The study of correlations with no definite causal order has revealed a rich structure emerging when more than two parties are involved. This motivates the consideration of multipar…
Bell's Theorem for Temporal Order
Magdalena Zych, Fabio Costa, Igor Pikovski +1
Time has a fundamentally different character in quantum mechanics and in general relativity. In quantum theory events unfold in a fixed time order while in general relativity tempo…
Causation does not explain contextuality
Sally Shrapnel, Fabio Costa
Realist interpretations of quantum mechanics presuppose the existence of elements of reality that are independent of the actions used to reveal them. Such a view is challenged by s…
A quantum causal discovery algorithm
Christina Giarmatzi, Fabio Costa
Finding a causal model for a set of classical variables is now a well-established task---but what about the quantum equivalent? Even the notion of a quantum causal model is controv…
