Relational Quantum Causal Processes toward Quantum Gravity with Controlled Einstein Response
Yipeng Xu
We construct a finite-Hilbert interacting quantum model in which matter and geometric response are generated by a single Schwinger functional along one spatial refinement. Two ineq…

Relational Quantum Causal Processes: Exact Models, Continuum Limits, and the Boundary of Emergent Gravity
Yipeng Xu
Relational quantum causal processes formulate finite operational contexts as normal positive functionals on local completely positive maps. Response differences generate an influen…

Emergence of Boolean Facts from Markovian Coarse-Graining in Relational Quantum Causal Processes
Yipeng Xu
We formulate an operator-algebraic mechanism by which exact Boolean records can arise from local completely positive quantum operations without being imposed as microscopic structu…
