赝束缚纠缠的实验产生

Experimental generation of pseudo bound entanglement

H. Kampermann, X. Peng, D. Bruss, D. Suter

摘要:

我们使用核磁共振(NMR)来实验性地产生束缚纠缠(更准确地说:伪束缚纠缠)态,即不可纠缠但仍然纠缠的量子态。我们的量子系统由三个量子比特组成。我们通过状态层析术来表征所产生的状态,以表明所产生的状态相对于任何二分分裂都具有正的部分转置,并且我们使用见证算子来证明其纠缠。

英文摘要:

We use Nuclear Magnetic Resonance (NMR) to experimentally generate a bound entangled (more precisely: pseudo bound entangled) state, i.e. a quantum state which is non-distillable but nevertheless entangled. Our quantum system consists of three qubits. We characterize the produced state via state tomography to show that the created state has a positive partial transposition with respect to any bipartite splitting, and we use a witness operator to prove its entanglement.
