ab: Summary: In a conventional quantum $(k, n)$ threshold scheme, a trusted
    party shares a secret quantum state with $n$ participants such that any
    $k$ of those participants can cooperate to recover the original secret,
    while fewer than $k$ participants obtain no information about the
    secret. In this paper we show how to construct a quantum $(k, n)$
    threshold scheme without the assistance of a trusted party, who
    generates and distributes shares among the participants. Instead, each
    participant chooses his private state and contributes the same to the
    determination of the final secret quantum state.
