Second-order topological insulator in a coinless discrete-time quantum walk
Ya Meng, Gang Chen, Suotang Jia
Higher-order topological insulators not only exhibit exotic bulk-boundary correspondence principle, but also have an important application in quantum computing. However, they have…

Topological quantum walks in cavity-based quantum networks
Ya Meng, Feng Mei, Gang Chen +1
We present a protocol to implement discrete-time quantum walks and simulate topological insulator phases in cavity-based quantum networks, where the single photon is the quantum wa…
