    "abstract": "We present a new protocol in which a secret multiqubit quantum state\n$\\ket{\\Psi}$ is shared by $n$ players and $m$ controllers, where $\\ket{\\Psi}$\nis the encoding state of a quantum secret sharing scheme. The players may be\nconsidered as field agents responsible for carrying out a task, using the\nsecret information encrypted in $\\ket{\\Psi}$, while the controllers are\nsuperiors who decide if and when the task should be carried out and who to do\nit. Our protocol only requires ancillary Bell states and Bell-basis\nmeasurements.",
