Composite N-Q-S: Serial/Parallel Instrument Axioms, Bipartite Order-Effect Bounds, and a Monitored Lindblad Limit
Kazuyuki Yoshida
We develop a composite operational architecture for sequential quantum measurements that (i) gives a tight bipartite order-effect bound with an explicit equality set characterized…

Intrinsic Geometry of Operational Contexts: A Riemannian-Style Framework for Quantum Channels
Kazuyuki Yoshida
We propose an intrinsic geometric framework on the space of operational contexts, specified by channels, stationary states, and self-preservation functionals. Each context C carrie…
