  Quantum networks are expected to enhance distributed quantum computing and
quantum communication over long distances while providing security dependent
upon physical effects rather than mathematical assumptions. Through simulation,
we show that a quantum network utilizing only entanglement purification or only
quantum error correction as error management strategies cannot create Bell
pairs with fidelity that exceeds the requirement for a secured quantum key
distribution protocol for a broad range of hardware parameters. We propose
hybrid strategies utilizing quantum error correction on top of purification and
show that they can produce Bell pairs of sufficiently high fidelity. We
identify the error parameter regime for gate and measurement errors in which
these hybrid strategies are applicable.
