張明強副教授與其博士後戴笠博士和郭華丞教授在自然子期刊科學報告 (Scientific Reports) 發表一篇文章，提出一個新的實驗方法，如何從新發現的拓樸馬約蘭那費米子(Majorana Fermions)提出量子糾纏態的方法，可以作為拓樸量子電腦的位元。
We propose a scheme for extracting entangled charge qubits from quantum-dot chains that support zero-energy edge modes. The edge mode is composed of Majorana fermions localized at the ends of each chain. The qubit, logically encoded in double quantum dots, can be manipulated through tunneling and pairing interactions between them. The detailed form of the entangled state depends on both the parity measurement (an even or odd number) of the boundary-site electrons in each chain and the teleportation between the chains.
The parity measurement is realized through the dispersive coupling of coherent-state microwave photons to the boundary sites, while the teleportation is performed via Bell measurements. Our scheme illustrates localizable entanglement in a fermionic system, which serves feasibly as a quantum repeater under realistic experimental conditions, as it allows for finite temperature effect and is robust against disorders, decoherence and quasi-particle poisoning.
