Fast Quantum State Discrimination with Nonlinear Positive Trace‐Preserving Channels
Fast Quantum State Discrimination with Nonlinear Positive Trace‐Preserving Channels
Abstract Models of nonlinear quantum computation based on deterministic positive trace‐preserving (PTP) channels and evolution equations are investigated. The models are defined in any finite Hilbert space, but the main results are for dimension . For every normalizable linear or nonlinear positive map ϕ on bounded linear operators X , …
