Bell nonlocality in networks

A Tavakoli, A Pozas-Kerstjens, MX Luo… - Reports on Progress in …, 2022 - iopscience.iop.org
Bell's theorem proves that quantum theory is inconsistent with local physical models. It has
propelled research in the foundations of quantum theory and quantum information science …

Quantum stochastic processes and quantum non-Markovian phenomena

S Milz, K Modi - PRX Quantum, 2021 - APS
The field of classical stochastic processes forms a major branch of mathematics. Stochastic
processes are, of course, also very well studied in biology, chemistry, ecology, geology …

Foundations for near-term quantum natural language processing

B Coecke, G de Felice, K Meichanetzidis… - arXiv preprint arXiv …, 2020 - arxiv.org
We provide conceptual and mathematical foundations for near-term quantum natural
language processing (QNLP), and do so in quantum computer scientist friendly terms. We …

The inflation technique for causal inference with latent variables

E Wolfe, RW Spekkens, T Fritz - Journal of Causal Inference, 2019 - degruyter.com
The problem of causal inference is to determine if a given probability distribution on
observed variables is compatible with some causal structure. The difficult case is when the …

Experimental nonclassicality in a causal network without assuming freedom of choice

E Polino, D Poderini, G Rodari, I Agresti… - Nature …, 2023 - nature.com
In a Bell experiment, it is natural to seek a causal account of correlations wherein only a
common cause acts on the outcomes. For this causal structure, Bell inequality violations can …

Genuine network multipartite entanglement

M Navascués, E Wolfe, D Rosset, A Pozas-Kerstjens - Physical Review Letters, 2020 - APS
The standard definition of genuine multipartite entanglement stems from the need to assess
the quantum control over an ever-growing number of quantum systems. We argue that this …

Cyclic quantum causal models

J Barrett, R Lorenz, O Oreshkov - Nature communications, 2021 - nature.com
Causal reasoning is essential to science, yet quantum theory challenges it. Quantum
correlations violating Bell inequalities defy satisfactory causal explanations within the …

[图书][B] Foundations of quantum programming

M Ying - 2024 - books.google.com
Quantum computers promise dramatic advantages in processing speed over currently
available computer systems. Quantum computing offers great promise in a wide variety of …

Embedding cyclic causal structures in acyclic spacetimes: no-go results for process matrices

V Vilasini, R Renner - arXiv, 2022 - research-collection.ethz.ch
Causality can be defined in terms of a space-time structure or based on information-theoretic
structures, which correspond to very different notions of causation. When analysing physical …

Causal structure in the presence of sectorial constraints, with application to the quantum switch

N Ormrod, A Vanrietvelde, J Barrett - Quantum, 2023 - quantum-journal.org
Existing work on quantum causal structure assumes that one can perform arbitrary
operations on the systems of interest. But this condition is often not met. Here, we extend the …
