Quantum information splitting with many-party controllers

© 2014 IEEE. In this paper, we develop an efficient and economic scheme in distributing quantum information scenario for remote partners via the control of many agents that are constrained by limited resources in a quantum communication network. Within such a network, quantum information is composed of multiple independent multi-qudit states, although each controlling agent is assigned only one controlling qudit, the agent can still control the distribution of all the quantum information. This scheme involves only generalized Bell-state measurement, single-qudit measurement and one-qudit gates, leading to a more flexible and achievable physical implementation.
