  1. The wave function as a true ensemble.Jonte Hance & Sabine Hossenfelder - 2022 - Proceedings of the Royal Society 478 (2262).
    In quantum mechanics, the wavefunction predicts probabilities of possible measurement outcomes, but not which individual outcome is realised in each run of an experiment. This suggests that it describes an ensemble of states with different values of a hidden variable. Here, we analyse this idea with reference to currently known theorems and experiments. We argue that the ψ-ontic/epistemic distinction fails to properly identify ensemble interpretations and propose a more useful definition. We then show that all local ψ-ensemble interpretations which reproduce (...)

  2. Could wavefunctions simultaneously represent knowledge and reality?Jonte Hance, John Rarity & James Ladyman - 2022 - Quantum Studies: Mathematics and Foundations 9 (3):333-341.
    In discussion of the interpretation of quantum mechanics the terms ‘ontic’ and ‘epistemic’ are often used in the sense of pertaining to what exists, and pertaining to cognition or knowledge respectively. The terms are also often associated with the formal definitions given by Harrigan and Spekkens for the wavefunction in quantum mechanics to be ψ-ontic or ψ-epistemic in the context of the ontological models framework. The formal definitions are contradictories, so that the wavefunction can be either ψ-epistemic or ψ-ontic but (...)

  3. How Quantum is Quantum Counterfactual Communication?Jonte R. Hance, James Ladyman & John Rarity - 2021 - Foundations of Physics 51 (1):1-17.
    Quantum Counterfactual Communication is the recently-proposed idea of using quantum physics to send messages between two parties, without any matter/energy transfer associated with the bits sent. While this has excited massive interest, both for potential ‘unhackable’ communication, and insight into the foundations of quantum mechanics, it has been asked whether this process is essentially quantum, or could be performed classically. We examine counterfactual communication, both classical and quantum, and show that the protocols proposed so far for sending signals that don’t (...)

  4. Bringing an End to the Interpretative Dispute on Descartes’s Cogito: the Cogito as Vérité, Cognitio, Propositio, and Conclusio.Ayumu Tamura - 2020 - Philosophy Journal 13 (3):38-48.
    The aim of this paper is to bring an end to the interpretative dispute on Descartes’s cog­ito: is the cogito known by intuition or by inference? There have been several studies based on both analytical and historical approaches to the dispute, and it seems that we have exhausted all interpretations. Nevertheless, I wish to revisit this dispute, as it ap­pears that the previous studies have overlooked Descartes’s use of words and phrases, which is the most significant for understanding his various (...)
