What does quantum parameter estimation estimate? A no-go result for true quantity values
Jacques L. Pienaar, Eran Tal, Asya Ciftci
We examine the conditions under which quantum parameter estimation is compatible with the concept of a ``true'' quantity value: a unique value of the estimated quantity that exists…
What is Physics For? Why Classical Physics is not the Limit of Quantum Mechanics
Adam Frank, Jacques L. Pienaar, Michel Bitbol +4
Quantum mechanics is justifiably held to be the most successful physical theory ever created; yet no universally accepted interpretation of its mathematical formalism exists after…
Quantum correlations in QBism's reconstruction program
Sachin Gupta, Jacques Pienaar
QBism recasts quantum theory as a normative framework for an agent's probability assignments, with the Born rule taking the form of a consistency condition known as the Urgleichung…
French on London and Bauer, and QBism
Jacques L. Pienaar
In this article I compare two interpretations of quantum mechanics (QM) that draw inspiration from phenomenology: the London-Bauer-French interpretation (hereafter LBF) as articula…
Synthesizing the Born rule with reinforcement learning
Rodrigo S. Piera, John B. DeBrota, Matthew B. Weiss +4
According to the subjective Bayesian interpretation of quantum theory (QBism), quantum mechanics is a tool that an agent would be wise to use when making bets about natural phenome…
A single space-time is too small for all of Wigner's friends
Jacques L. Pienaar
Recent no-go theorems on interpretations of quantum theory featuring an assumption of `Absoluteness of Observed Events' (AOE) are shown to have an unexpectedly strong corollary: on…
Entanglement decoherence in a gravitational well according to the event formalism
T. C. Ralph, J. Pienaar
The event formalism is a non-linear extension of quantum field theory designed to be compatible with the closed time-like curves that appear in general relativity. Whilst reducing…
Quantum fields on closed time-like curves
J. L. Pienaar, C. R. Myers, T. C. Ralph
Recently, there has been much interest in the evolution of quantum particles on closed time-like curves (CTCs). However, such models typically assume point-like particles with only…
