Rigidity of quantum steering and one-sided device-independent verifiable quantum computation

- Alexandru Gheorghiu, P. Wallden, E. Kashefi
- Mathematics, Physics
- 23 December 2015

The relationship between correlations and entanglement has played a major role in understanding quantum theory since the work of Einstein, Podolsky and Rosen (1935). Tsirelson (1980) proved that Bell… Expand

Spacelike distance from discrete causal order

- D. Rideout, P. Wallden
- Physics
- 9 October 2008

Any discrete approach to quantum gravity must provide some prescription as to how to deduce continuum properties from the discrete substructure. In the causal set approach it is straightforward to… Expand

A histories perspective on characterizing quantum non-locality

- Fay Dowker, J. Henson, P. Wallden
- Physics
- 25 November 2013

We introduce a framework for studying non-locality and contextuality inspired by the path integral formulation of quantum theory. We prove that the existence of a strongly positive joint quantum… Expand

Quantum Covers in Quantum Measure Theory

- S. Surya, P. Wallden
- Mathematics, Physics
- 11 September 2008

Sorkin’s recent proposal for a realist interpretation of quantum theory, the anhomomorphic logic or coevent approach, is based on the idea of a “quantum measure” on the space of histories. This is a… Expand
