Susceptibility of qudit-qudit entanglement to quantum noise: insights from the negativity rank
The paper investigates how negativity rank, a measure of entanglement robustness, affects qudit-qudit entanglement under global depolarizing noise. It finds that this rank dictates the rate at which entanglement decays and establishes bounds for maximally entangled states in various subspaces. This provides guidance for designing robust quantum systems against noise.
