For a specified quantum causal graph with hidden systems and restricted interventions, characterize which causal effects are identifiable and derive complete inference procedures and sample-complexity bounds, or prove…
Determine how the physically realizable process class changes when specified closed-laboratory, spacetime-localization or background-causality assumptions are relaxed, and give operational implementations or…
For a specified symmetry group and constrained dynamics, bound errors in changing and composing finite-resource quantum frames, including interacting clock backreaction and repeated-use degradation under an explicit…
Given limited Hamiltonian and observable data, characterize existence, uniqueness and stability of an approximately local tensor-product structure, modulo stated local-unitary and subsystem-permutation equivalences.
For a specified Hamiltonian or dissipative dynamics, observable class and semiclassical or many-body scaling, prove quantitative quantum-to-classical error bounds on a stated growing time window; separate isolated…
For a specified system–environment dynamics and fragment-access model, bound the formation time, redundancy, disturbance and lifetime of independently accessible classical records, using an explicit objectivity…
For specified Wigner's-friend protocols, identify which assumptions about record persistence, laboratory coherence and agents' conditioning are operationally testable, and derive robust constraints separating the…
For specified operational axioms and composite-system rules, establish their independence and reconstruction power, and determine which alternative theories are experimentally distinguishable; extend controlled…
For a specified ontology and dynamics, give a precise account of measurement records and their probabilities without an undefined system–observer cut; identify experimentally distinguishable predictions or explain why…
