We present a systematic extension of the Riemann zeta function from complex parameters to infinite-dimensional Hilbert space operator parameters, establishing a rigorous mathematical framework for operator-valued zeta functions. Through spectral theory, functional calculus, and de Branges space theory, we construct complete definitions of (ˆS) where ˆS is an operator on Hilbert space. This extension not only preserves the analytic properties of the original zeta function but also revealsdeep connections between algorithmic encoding, quantum systems, and geometric structures. We prove an operator generalization of Voronin’s universality theorem, establish an operator realization of the Hilbert-P´olya hypothesis, and unify com- putation and data duality through operator extensions of Fourier transforms. This framework provides a unified mathematical foundation for understanding computational complexity, quantum entanglement, and information geometry.
