Query: Semiquantum key distribution with secure delegated quantum computation   Semiquantum key distribution allows a quantum party to share a random key
with a "classical" party who only can prepare and measure qubits in the
computational basis or reorder some qubits when he has access to a quantum
channel. In this work, we present a protocol where a secret key can be
established between a quantum user and an almost classical user who only needs
the quantum ability to access quantum channels, by securely delegating quantum
computation to a quantum server. We show the proposed protocol is robust even
when the delegated quantum server is a powerful adversary, and is
experimentally feasible with current technology. As one party of our protocol
is the most quantum-resource efficient, it can be more practical and
significantly widen the applicability scope of quantum key distribution.
