  In extant quantum secret sharing protocols, once the secret is shared in a
quantum network (\textsc{qnet}) it can not be retrieved back, even if the
dealer wishes that her secret no longer be available in the network. For
instance, if the dealer is part of two \textsc{qnet}s, say $\mathcal{Q}_1$ and
$\mathcal{Q}_2$ and subsequently finds that $\mathcal{Q}_2$ is more reliable
than $\mathcal{Q}_1$, the dealer may wish to transfer all her secrets from
$\mathcal{Q}_1$ to $\mathcal{Q}_2$. In this work we address this problem by
designing a protocol that enables the source/dealer to bring back the
information shared in the network, if desired. Unlike classical revocation,
no-cloning-theorem automatically ensures that the secret is no longer shared in
the network.
  The implications of our results are multi-fold. One interesting implication
of our technique is the possibility of routing qubits in asynchronous
\textsc{qnets}. By asynchrony we mean that the requisite data/resources are
intermittently available (but not necessarily simultaneously) in the
\textsc{qnet}. For example, we show that a source $S$ can send quantum
information to a destination $R$ even though (a) $S$ and $R$ share no quantum
resource, (b) $R$'s identity is {\em unknown}\/ to $S$ initially, (c) $S$
herself can be $R$ at a later date and/or in a different location to bequeath
her information and (d) the path chosen for routing the secret may hit a
dead-end due to resource constraints. Another implication of our technique is
the possibility of using {\em insecure}\/ resources. For instance, it may
safely store its private information with a neighboring organization without
revealing data to the host and losing control over retrieving the data.
  Putting the two implications together, namely routing and secure storage, it
is possible to envision applications like quantum mail (qmail) as an outsourced
service.
