Classical Causal Models for Bell and Kochen-Specker Inequality Violations Require Fine-Tuning
Recent Articles in Phys. Rev. X
Author(s): Eric G. Cavalcanti
A new analysis puts quantum nonlocality and contextuality—key resources for quantum computing—on equal theoretical footing as violations of classical causality.

Reply to “Comment on ‘Null weak values and the past of a quantum particle”’
PRA: Fundamental concepts
Author(s): Q. Duprey and A. Matzkin
We discuss the preceding Comment [D. Sokolovski, preceding Comment, Phys. Rev. A 97, 046102 (2018)] and conclude that the arguments given there against the relevance of null weak values as representing the absence of a system property are not compelling. We give an example in which the transition ma…

In a recent paper [Phys. Rev. A 95, 032110 (2017)], Duprey and Matzkin investigated the meaning of vanishing weak values and their role in the retrodiction of the past of a preselected and postselected quantum system in the presence of interference. Here we argue that any proposition regarding the w…

Principle of Unattainability of Absolute Zero Temperature, The Third Law of Thermodynamics, and Projective Quantum Measurements. (arXiv:1804.04182v1 [quant-ph])
quant-ph updates on arXiv.org
Authors: Tien D. Kieu
The Principle of Unattainability rules out the attainment of absolute zero temperature by any finite physical means, no matter how idealised they could be. Nevertheless, we clarify that the Third Law of Thermodynamics, as defined by Nernst’s heat theorem statement, is distinct from the Principle of Unattainability in the sense that the Third Law is mathematically equivalent only to the unattainability of absolute zero temperature by {\em quasi-static adiabatic} processes. This thus leaves open the possibility of attainability of absolute zero, without violating the Third Law, by non-adiabatic means. Such a means may be provided in principle and in particular by projective measurements in quantum mechanics. This connection also establishes some intimate relationship between the postulate of projective measurement and the Principle of Unattainability.
Clock–Work Trade-Off Relation for Coherence in Quantum Thermodynamics
PRL: General Physics: Statistical and Quantum Mechanics, Quantum Information, etc.
Author(s): Hyukjoon Kwon, Hyunseok Jeong, David Jennings, Benjamin Yadin, and M. S. Kim
In thermodynamics, quantum coherences—superpositions between energy eigenstates—behave in distinctly nonclassical ways. Here we describe how thermodynamic coherence splits into two kinds—“internal” coherence that admits an energetic value in terms of thermodynamic work, and “external” coherence that…

A new theoretical analysis derives a precise fundamental lower limit to the work cost for processing information in any type of system, thereby cornering a new microscopic formulation of thermodynamics and shedding light on how far the second law can be applied.

Scheme for the protective measurement of a single photon using a tunable quantum Zeno effect
PRA: Fundamental concepts
Author(s): Maximilian Schlosshauer
This paper presents a proof-of-principle scheme for the protective measurement of a single photon. In this scheme, the photon is looped arbitrarily many times through an optical stage that implements a weak measurement of a polarization observable followed by a strong measurement protecting the stat…
