Biphoton entanglement of topologically-distinct modes
Cooper Doyle, Wei-Wei Zhang, Michelle Wang +3
The robust generation and manipulation of entangled multiphoton states on-chip has an essential role in quantum computation and communication. Lattice topology has emerged as a mea…
Channel Discord and Distortion
Wei-Wei Zhang, Yuval R. Sanders, Barry C. Sanders
Discord, originally notable as a signature of bipartite quantum correlation,in fact can be nonzero classically, i.e., arising from noisy measurements by one of the two parties. Her…
Topological quantum walks: theory and experiments
Jizhou Wu, Wei-Wei Zhang, Barry C. Sanders
Inspired by recent breakthroughs with topological quantum materials, which pave the way to novel, high-efficiency, low-energy magnetoelectric devices and fault-tolerant quantum inf…
Quantum topology identification with deep neural networks and quantum walks
Yurui Ming, Chin-Teng Lin, Stephen D. Bartlett +1
Topologically ordered materials may serve as a platform for new quantum technologies such as fault-tolerant quantum computers. To fulfil this promise, efficient and general methods…
Uncover Topology by Quantum Quench Dynamics
Wei Sun, Chang-Rui Yi, Bao-Zong Wang +9
Topological quantum states are characterized by nonlocal invariants, and their detection is intrinsically challenging. Various strategies have been developed to study topological H…
Detecting topological transitions in two dimensions by Hamiltonian evolution
Wei-Wei Zhang, Barry C. Sanders, Simon Apers +2
We show that the evolution of two-component particles governed by a two-dimensional spin-orbit lattice Hamiltonian can reveal transitions between topological phases. A kink in the…
Quantum walk on a chimera graph
Shu Xu, Xiangxiang Sun, Jizhou Wu +3
We analyze a continuous-time quantum walk on a chimera graph, which is a graph of choice for designing quantum annealers, and we discover beautiful quantum-walk features such as lo…
Decomposition of split-step quantum walks for simulating Majorana modes and edge states
Wei-Wei Zhang, Sandeep K. Goyal, Christoph Simon +1
We construct a decomposition procedure for converting split-step quantum walks into ordinary quantum walks with alternating coins, and we show that this decomposition enables a fea…
Creating cat states in one-dimensional quantum walks using delocalized initial states
Wei-Wei Zhang, Sandeep K. Goyal, Fei Gao +2
Cat states are coherent quantum superpositions of macroscopically distinct states and are useful for understanding the boundary between the classical and the quantum world. Due to…
Quantum walks on two kinds of two-dimensional models
Dan Li, Michael Mc Gettrick, Wei-Wei Zhang +1
In this paper, we numerically study quantum walks on two kinds of two-dimensional graphs: cylindrical strip and Mobius strip. The two kinds of graphs are typical two-dimensional to…
One dimensional lazy quantum walks and occupancy rate
Dan Li, Michael Mc Gettrick, Wei-Wei Zhang +1
Lazy quantum walks were presented by Andrew M. Childs to prove that the continuous-time quantum walk is a limit of the discrete-time quantum walk [Commun.Math.Phys.294,581-603(2010…
