Low Homotopy and Noise-Stable Choi-Band Topology of Fixed-Kraus-Rank Quantum Channels

We determine a strict-interior low-homotopy window for finite-dimensional exact-Kraus-rank CPTP channel manifolds, treat feasibility and boundary branches, identify low-stage Choi-support Chern invariants, construct a trace-preserving qubit S4 Yang-monopole channel with |c2|=1, a...

Recognition, Rigidity, and Dimension from Directed Quantum Distinguishability

This record contains the manuscript, unified Supplemental Material, source files, author-generated analysis code, derived numerical products, figures, and provenance material supporting *Recognition, Rigidity, and Dimension from Directed Quantum Distinguishability*. For faithful...

Operator-Growth Obstruction to Annealed Hilbert-Schmidt Mixing in Dissipative SYK

We prove an annealed Hilbert-Schmidt mixing obstruction in Gaussian dissipative q=4 Sachdev-Ye-Kitaev dynamics. Exact finite-N parity-size conjugacy and a frame-integrated-size identity are combined with a nonperturbative Rademacher-SYK operator-growth theorem and a fourth-order...

Green-Kubo Memory, Irreversibility, and Experimental-Data Tests from Ordered Absorption

What dynamical information can be inferred when an experiment records only whether a system survives controlled absorption? Static state-dependent absorption is exactly blind to stationary time reversal, even when complete survival curves are known. Two ordered pulses recover lag...

Green–Kubo Memory and Irreversibility from Ordered Absorption

What dynamical information can be inferred when an experiment records only whether a system survives a controlled absorption protocol? Static state-dependent absorption is exactly blind to stationary time reversal, even when complete survival curves are known. We show that two or...
