Intrinsic bounds of a two-qudit random evolution
Abstract
We investigate entangled qudits evolving under random, local SU(d) operations and demonstrate that this evolution is constrained by intrinsic bounds, showing robust features of two-qudit entangled states that can be useful for fault tolerant implementations of phase gates. Our analytical results are supported by numerical simulations and confirmed by experiments on liquid-state nuclear magnetic resonance qubits.
