A review and analysis of six extended Wigner's friend arguments

David Schmid, Yìlè Yīng, Matthew Leifer

The Wigner's friend thought experiment was intended to illustrate the difficulty one has in describing an agent as a quantum system when that agent performs a measurement. While it…

Uncertainty from the Aharonov-Vaidman Identity

M. S. Leifer

In this article, I show how the Aharonov-Vaidman identity $A \left \vert ψ\right \rangle = \left \langle A \right \rangle \left \vert ψ\right \rangle + ΔA \left \vert ψ^{\perp}_A \…

Aspects of the phenomenology of interference that are genuinely nonclassical

Lorenzo Catani, Matthew Leifer, Giovanni Scala +2

Interference phenomena are often claimed to resist classical explanation. However, such claims are undermined by the fact that the specific aspects of the phenomenology upon which…

Reply to "Comment on 'Why interference phenomena do not capture the essence of quantum theory' "

Lorenzo Catani, Matthew Leifer, David Schmid +1

Our article [arXiv:2111.13727(2021)] argues that the phenomenology of interference that is traditionally regarded as problematic does not, in fact, capture the essence of quantum t…

What is nonclassical about uncertainty relations?

Lorenzo Catani, Matthew Leifer, Giovanni Scala +2

Uncertainty relations express limits on the extent to which the outcomes of distinct measurements on a single state can be made jointly predictable. The existence of nontrivial unc…

Generalising Aumann's Agreement Theorem

Matthew Leifer, Cristhiano Duarte

According to Aumann's celebrated theorem, rational agents cannot agree to disagree. In other words, agents who once shared a common prior probability distribution and who have comm…
