• Quantum operation sharing
• generalized seven-qubit Brown state
• four-party scheme

In this paper, a four-party scheme is presented for remotely sharing a single-qubit operation with the help of LOCC and the generalized seven-qubit Brown state |B7 >. Besides, we consider a theoretical scheme for four-party QOS by using the generalized (2N+1)-qubit Brown state |B2N+1 >(N >= 2)| proposed by Muralidharan and Panigrahi (Phys. Rev. A 77 (2008) 032321). Furthermore, some concrete discussions are made to study its important features, including the scheme determinacy, the sharer symmetry, the scheme security, the nowadays experimental feasibility as well as the intrinsic efficiency.
