We draw attention to the existence of “genuine” fidelity gaps in an ancilla-assisted sequential decomposition of genuinely entangling isometry and unitary operations of quantum computing. The gaps arise upon a bipartite decomposition of a multiqubit operation in a one-way sequential recipe in which an ancillary system interacts locally and only once with each qubit in a row. Given the known “no-go” associated with such a theoretically and experimentally desirable decomposition, various figures…

This work considers the deterministic generation of entangled multiqubit states by the sequential coupling of an ancillary system to initially uncorrelated qubits and shows, in particular, how to generate familiar quantum information states such as W, Greenberger-Horne-Zeilinger, and cluster states within such a framework.

It is proved that in large dimensions, almost all bipartite unitaries have entangling and disentangling capacities close to maximal, and that there can be no unique ordering for unitary gates in terms of their ability to perform nonlocal tasks.
