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…
Enhanced Density Fluctuations Near a Disordered Chiral Topological Transition
Hai-Tao Ding, Sen Mu, Leong-Chuan Kwek +2
The universal statistics of density fluctuations of localized quantum states may offer unprecedented opportunities to probe and understand quantum transport in connection with dime…
Floquet quantum geometry in periodically driven topological insulators
Peng He, Jian-Te Wang, Jiangbin Gong +1
Quantum geometry plays a fundamental role across many branches of modern physics, yet its full characterization in nonequilibrium systems remains a challenge. Here, we propose a fr…
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…
