鲁棒高效的几乎最大多体纠缠generator

Robust and efficient generator of almost maximal multipartite entanglement

Davide Rossini, Giuliano Benenti

摘要:

量子混沌映射可以有效地产生具有几乎最大多体纠缠的伪随机态,其特征在于系统所有可能的二分体之间的二分体纠缠的概率分布。我们表明,这样的多体纠缠是强大的,在这个意义上说,当现实的噪声被认为是,bipartitions的可压缩纠缠仍然几乎最大的噪声强度下降,只有多项式与量子位数。

英文摘要:

Quantum chaotic maps can efficiently generate pseudo-random states carrying almost maximal multipartite entanglement, as characterized by the probability distribution of bipartite entanglement between all possible bipartitions of the system. We show that such multipartite entanglement is robust, in the sense that, when realistic noise is considered, distillable entanglement of bipartitions remains almost maximal up to a noise strength that drops only polynomially with the number of qubits.
