Manipulation of Topological Corner States via Subchiral Symmetry
Hai-Tao Ding, Tianqi Chen, Leong-Chuan Kwek +1
Higher-order topological phases provide robust corner modes, but their use requires controllable creation, isolation, and transfer of individual modes and their superpositions. Her…
Nonadiabatic braiding of Majorana modes
Fei Yu, P. Z. Zhao, Jiangbin Gong
The realization and manipulation of Majorana zero modes have drawn significant attention for their crucial role in enabling topological quantum computation. Conventional approaches…
Higher-order protection of quantum gates: Hamiltonian engineering coordinated with dynamical decoupling
P. Z. Zhao, Tianqi Chen, Sirui Liu +1
Dynamical decoupling represents an active approach towards the protection of quantum memories and quantum gates. Because dynamical decoupling operations can interfere with a system…
Mitigation of systematic amplitude error in nonadiabatic holonomic operations
P. Z. Zhao, Jiangbin Gong
Nonadiabatic holonomic operations are based on nonadiabatic non-Abelian geometric phases, hence possessing the inherent geometric features for robustness against control errors. Ho…
Direct Probe of Topology and Geometry of Quantum States on IBM Q
Tianqi Chen, Hai-Tao Ding, Ruizhe Shen +2
The concepts of topology and geometry are of critical importance in exploring exotic phases of quantum matter. Though they have been investigated on various experimental platforms,…
