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…
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…
