Summary

Sequential Bell measurements let separated inputs feed optimal probabilistic telecloning without a global measurement.

The protocol distributes N copies of an unknown state to M receivers using sequential or parallel Bell-state measurements. Successful runs saturate the no-cloning fidelity bound with success probability independent of receiver count; even unsuccessful measurements can reveal partial information about the nearest Pauli basis. The paper analyzes resources and bounds theoretically rather than reporting a deployed quantum network.

Why it matters

Sequential Bell measurements let separated inputs feed optimal probabilistic telecloning without a global measurement.
