Universal energy-space localization and stable quantum phases against time-dependent perturbations
Hongye Yu, Tzu-Chieh Wei
Stability against perturbations is a highly nontrivial property of quantum systems and is often a requirement to define new phases. In most systems where stability can be rigorousl…
The robustness condition for general disordered discrete time crystals, and subspace-thermal DTCs from phase transitions between different n-tuple DTCs
Hongye Yu, Tzu-Chieh Wei
We propose a new Floquet time crystal model that responds in arbitrary multiples of the driving period. Such an -tuple discrete time crystal is theoretically constructed by perm…
Feedback-based Quantum Algorithm Inspired by Counterdiabatic Driving
Rajesh K. Malla, Hiroki Sukeno, Hongye Yu +3
In recent quantum algorithmic developments, a feedback-based approach has shown promise for preparing quantum many-body system ground states and solving combinatorial optimization…
Efficient separate quantification of state preparation errors and measurement errors on quantum computers and their mitigation
Hongye Yu, Tzu-Chieh Wei
Current noisy quantum computers have multiple types of errors, which can occur in the state preparation, measurement/readout, and gate operation, as well as intrinsic decoherence a…
Quantum Hamiltonian Algorithms for Maximum Independent Sets
Xianjue Zhao, Peiyun Ge, Hongye Yu +3
With qubits encoded into atomic ground and Rydberg states and situated on the vertexes of a graph, the conditional quantum dynamics of Rydberg blockade, which inhibits simultaneous…
Simulating large-size quantum spin chains on cloud-based superconducting quantum computers
Hongye Yu, Yusheng Zhao, Tzu-Chieh Wei
Quantum computers have the potential to efficiently simulate large-scale quantum systems for which classical approaches are bound to fail. Even though several existing quantum devi…
Geometric quantum adiabatic methods for quantum chemistry
Hongye Yu, Deyu Lu, Qin Wu +1
Existing quantum algorithms for quantum chemistry work well near the equilibrium geometry of molecules, but the results can become unstable when the chemical bonds are broken at la…
Quantum Zeno approach for molecular energies with maximum commuting initialHamiltonians
Hongye Yu, Tzu-Chieh Wei
We propose to use a quantum adiabatic and simulated-annealing framework to compute theground state of small molecules. The initial Hamiltonian of our algorithms is taken to be them…
Quantum independent set problem and non-abelian adiabatic mixing
Biao Wu, Hongye Yu, Frank Wilczek
We present an efficient quantum algorithm for some independent set problems in graph theory, based on non-abelian adiabatic mixing. We illustrate the performance of our algorithm w…
Exact Equivalence between Quantum Adiabatic Algorithm and Quantum Circuit Algorithm
Hongye Yu, Yuliang Huang, Biao Wu
We present a rigorous proof that quantum circuit algorithm can be transformed into quantum adiabatic algorithm with the exact same time complexity. This means that from a quantum c…
