computing using an ion trap as server and a measurement-only client. While the
client has no direct access to quantum-computing resources, it can remotely execute
quantum programs on the server by measuring entangled photons that are emitted
by the ion trap. We introduce a numerical model for trapped-ion quantum devices in
NetSquid, a discrete-event simulator for quantum networks. Using this, we determine
the minimal hardware requirements and minimal improvements over the current state
of the art required to perform ε-secure verifiable blind quantum computing with a
universal resource for single-qubit rotations over 50 km of optical fiber. Current
state-of-the-art ion traps satisfy absolute minimal requirements on a per-parameter
basis, but all current imperfections combined make it impossible to perform the blind
computation securely over 50 km using existing technology. Using a genetic algorithm
we determine the set of hardware parameters that minimizes the total improvements
required, laying a path for the near-term experimental progress required to realize a
trapped ion-based quantum internet.
