Partition of arbitrary single-qubit information among n recipients via asymmetric(n+1)-qubit W state

【摘要】:A symmetric and(n,n)-threshold scheme for a sender to partition his/her arbitrary single-qubit information among n recipients is proposed by using a newly constructed asymmetric(n+1)-qubit W state.Both the scheme in some given scenarios and the new W state are also discussed given.
