Correlational quantum theory and correlation constraints
Ding Jia
A correlational dialect is introduced within the quantum theory language to give a unified treatment of finite-dimensional informational/operational quantum theories, infinite-dime…
Causally neutral quantum physics
Ding Jia
In fundamental theories that accounts for quantum gravitational effects, the spacetime causal structure is expected to be quantum uncertain. Previous studies of quantum causal stru…
Causal order as a resource for quantum communication
Ding Jia, Fabio Costa
In theories of communication, it is usually presumed that the involved parties perform actions in a fixed causal order. However, practical and fundamental reasons can induce uncert…
Quantum from principles without assuming definite causal structure
Ding Jia
There has been a body of works deriving the complex Hilbert space structure of quantum theory from axioms/principles/postulates to deepen our understanding about quantum theory and…
Reduction of correlations by quantum indefinite causal structure
Ding Jia
We show that quantum indefinite causal structure generically reduce two-party correlations. For significant indefiniteness in the causal structure captured by some general conditio…
Quantum field theory with indefinite causal structure
Ding Jia
Quantum field theory (QFT) in classical spacetime has revealed interesting and puzzling aspects about gravitational systems, in particular black hole thermodynamics and its informa…
