Evidence for the epistemic view of quantum states: A toy theory

- R. Spekkens
- Physics
- 9 January 2004

We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in a… Expand

Contextuality for preparations, transformations, and unsharp measurements

- R. Spekkens
- Physics
- 23 June 2004

The Bell-Kochen-Specker theorem establishes the impossibility of a noncontextual hidden variable model of quantum theory, or equivalently, that quantum theory is contextual. In this paper, an… Expand

Foundations of Quantum Mechanics

General Instructions Write your CANDIDATE NUMBER clearly on each of the THREE answer books provided. If an electronic calculator is used, write its serial number in the box at the top right hand… Expand

Reference frames, superselection rules, and quantum information

- S. Bartlett, T. Rudolph, R. Spekkens
- Physics
- 5 October 2006

Recently, there has been much interest in a new kind of 'unspeakable' quantum information that stands to regular quantum information in the same way that a direction in space or a moment in time… Expand

The lesson of causal discovery algorithms for quantum correlations: causal explanations of Bell-inequality violations require fine-tuning

- C. J. Wood, R. Spekkens
- Physics
- 20 August 2012

An active area of research in the fields of machine learning and statistics is the development of causal discovery algorithms, the purpose of which is to infer the causal relations that hold among a… Expand

Einstein, Incompleteness, and the Epistemic View of Quantum States

TLDR

Resource theory of quantum states out of thermal equilibrium.

- F. Brandão, M. Horodecki, J. Oppenheim, J. Renes, R. Spekkens
- Physics, Medicine

TLDR

Towards a formulation of quantum theory as a causally neutral theory of Bayesian inference

- M. Leifer, R. Spekkens
- Physics
- 29 July 2011

Quantum theory can be viewed as a generalization of classical probability theory, but the analogy as it has been developed so far is not complete. Whereas the manner in which inferences are made in… Expand

Contextuality for preparations, transformations, and unsharp measurements (17 pages)

- R. Spekkens
- Physics
- 2005

Quantum protocol for cheat-sensitive weak coin flipping.

- R. Spekkens, T. Rudolph
- Computer Science, Physics
- Physical review letters
- 21 February 2002

We present a quantum protocol for the task of weak coin flipping. We find that, for one choice of parameters in the protocol, the maximum probability of a dishonest party winning the coin flip if the… Expand
