WebOct 10, 2008 · We consider three broad classes of quantum secret sharing with and without eavesdropping and show how a graph state formalism unifies otherwise disparate quantum secret sharing models. In addition to the elegant unification provided by graph states, our approach provides a generalization of threshold classical secret sharing via insecure … WebAssuming this is the case, the reason we can write the state like this can be seen by considering a simpler case. First, we observer that the two-vertex line graph L 2 can be written as: L 2 = 1 2 ( + + + − − ) whereas the state associated with the three-qubit line L 3 can be written as

GraphState. Circuit to prepare a graph state. Given a graph G = (V, E), with the set of vertices V and the set of edges E, the corresponding graph state is defined as. Such a state can be prepared by first preparing all qubits in the + state, then applying a C Z gate for each corresponding graph edge. In quantum computing, a graph state is a special type of multi-qubit state that can be represented by a graph. Each qubit is represented by a vertex of the graph, and there is an edge between every interacting pair of qubits. In particular, they are a convenient way of representing certain types of entangled states. … See more Quantum graph states can be defined in two equivalent ways: through the notion of quantum circuits and stabilizer formalism.
