Extending the Agent in QBism
Jacques Pienaar
According to the subjective Bayesian interpretation of quantum mechanics (QBism), the instruments used to measure quantum systems are to be regarded as an extension of the senses o…
A time-reversible quantum causal model
Jacques Pienaar
Modern approaches to causal modeling give a central role to interventions, which require the active input of an observer and introduces an explicit `causal arrow of time'. Causal m…
Comment on `The notion of locality in relational quantum mechanics'
Jacques Pienaar
A recent paper [P. Martin-Dussaud, C. Rovelli, F. Zalamea, arXiv:1806.08150] has given a lucid treatment of Bell's notion of local causality within the framework of the relational…
Quantum causal models via QBism: the short version
Jacques Pienaar
This paper is a concise summary of the main ideas presented in the companion paper `Quantum causal models via Quantum Bayesianism'[arXiv:1806.00895]. I present the proposed definit…
Quantum causal models via QBism
Jacques Pienaar
This paper presents a framework for Quantum causal modeling based on the interpretation of causality as a relation between an observer's probability assignments to hypothetical or…
Space-time qubits
J. L. Pienaar, C. R. Myers, T. C. Ralph
We construct a qubit algebra from field creation and annihilation operators acting on a global vacuum state. Particles to be used as qubits are created from the vacuum by a near-de…
