A Recursive Module-Coupling Algorithm for Computing Low-Energy Eigenstates
Dihang Sun, Nannan Ma, Ching Hua Lee +2
Finding the eigenstates of a many-body Hamiltonian is a fundamental challenge in physics and computational science. Since the search space grows exponentially with system size, num…
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…
Quantum machine learning with indefinite causal order
Nannan Ma, P. Z. Zhao, Jiangbin Gong
In a conventional circuit for quantum machine learning, the quantum gates used to encode the input parameters and the variational parameters are constructed with a fixed order. The…
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,…
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…
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…
