### Quantum correlations which imply causation

- PhysicsScientific reports
- 2015

This work introduces the concept of a pseudo-density matrix (PDM) which treats space and time indiscriminately and defines a measure of causality that discriminates between spatial and temporal correlations.

### Quantum Logic and the Histories Approach to Quantum Theory

- Physics, Philosophy
- 1993

An extended analysis is made of the Gell-Mann and Hartle axioms for a generalised ‘histories’ approach to quantum theory. Emphasis is placed on ﬁnding equivalents of the lattice structure that is…

### Quantum correlations with no causal order

- PhilosophyNature communications
- 2012

It is shown that in a classical limit causal order always arises, which suggests that space-time may emerge from a more fundamental structure in a quantum-to-classical transition.

### Quantum-coherent mixtures of causal relations

- Physics, PhilosophyNature communications
- 2017

This work realizes this nonclassical causal relation in a quantum optics experiment and derives a set of criteria for witnessing the coherence based on a quantum version of Berkson's effect, whereby two independent causes can become correlated on observation of their common effect.

### Connecting processes with indefinite causal order and multi-time quantum states

- Philosophy, Mathematics
- 2017

It is shown that process matrices are equivalent to a particular class of pre- and post-selected quantum states, which offers a new conceptual point of view to the nature of process Matrices.

### Measurement of time by quantum clocks

- Physics
- 1980

A clock is a dynamical system which passes through a succession of states at constant time intervals. If coupled to another system, it can measure the duration of a physical process and even keep a…

This chapter discusses quantum entanglement, computation and quantum measurements, as well as classical and quantum mechanics, and some of the algorithms used to solve these problems.

### Classical, quantum and total correlations

- Physics
- 2001

We discuss the problem of separating consistently the total correlations in a bipartite quantum state into a quantum and a purely classical part. A measure of classical correlations is proposed and…
