## Weekly Papers on Quantum Foundations (36)

Gravitational redshift induces quantum interference. (arXiv:2109.00728v1 [quant-ph]) 上午10:13 | David Edward Bruschi, Andreas W. Schell | quant-ph updates on arXiv.org We use quantum field theory in curved spacetime to show that gravitational redshift induces a unitary transformation on the quantum state of propagating photons. This occurs for realistic photons characterized by a finite bandwidth, while ideal photons with sharp frequencies… Read more →

## Weekly Papers on Quantum Foundations (23)

Testing Bell inequalities in Higgs boson decays. (arXiv:2106.01377v1 [hep-ph]) 下午5:25 | Alan Barr | quant-ph updates on arXiv.org Higgs boson decays produce pairs of W bosons in a maximally entangled state, the spins of which can be expected to violate Bell inequalities. We show that the spin density matrix of the $W^\pm$ pair may be reconstructed experimentally from the directions… Read more →

## Lapsing Quickly into Fatalism: Bell on Backward Causation

Travis Norsen, Huw Price This is a dialogue between Huw Price and Travis Norsen, loosely inspired by a letter that Price received from J. S. Bell in 1988. The main topic of discussion is Bell’s views about retrocausal approaches to quantum theory, and their relevance to contemporary issues. Full text

## Realism and Causality II: Retrocausality in Energetic Causal Sets

Eliahu Cohen, Marina Cortês, Avshalom C. Elitzur, Lee Smolin (Submitted on 13 Feb 2019 (v1), last revised 19 Mar 2019 (this version, v2)) https://arxiv.org/abs/1902.05082v2 We describe a new form of retrocausality, which is found in the behaviour of a class of causal set theories, called energetic causal sets (ECS). These are discrete sets of events, connected by causal relations. They have three orders:… Read more →

## Realism and causality I: Pilot wave and retrocausal models as possible facilitators

Eliahu Cohen, Marina Cortês, Avshalom C. Elitzur, Lee Smolin (Submitted on 13 Feb 2019 (v1), last revised 19 Mar 2019 (this version, v2)) https://arxiv.org/abs/1902.05108v2 Of all basic principles of classical physics, realism should arguably be the last to be given up when seeking a better interpretation of quantum mechanics. We examine the de Broglie-Bohm pilot wave theory as a well developed example of… Read more →

## Realistic interpretation of quantum mechanics and encounter-delayed-choice experiment

GuiLu Long et al (Tsinghua University) In this paper, a realistic interpretation (REIN) of the wave function in quantum mechanics is briefly presented. We demonstrate that in the REIN, the wave function of a microscopic object is its real existence rather than a mere mathematical description. Specifically, the quantum object can exist in disjointed regions of space just as the… Read more →

## Determining the Quantum Expectation Value by Measuring a Single Photon: The first realisation of quantum protective measurements

F. Piacentini, A. Avella, E. Rebufello, R. Lussana, F. Villa, A. Tosi, M. Gramegna, G. Brida, E. Cohen, L. Vaidman, I. P. Degiovanni, M. Genovese Quantum mechanics, one of the keystones of modern physics, exhibits several peculiar properties, differentiating it from classical mechanics. One of the most intriguing is that variables might not have definite values. A complete quantum description provides only probabilities for obtaining various eigenvalues of a quantum variable….
