Detecting quantum phase transitions via shallow variational quantum circuits
Ching-Yu Huang, Min-Fong Yang
Mapping quantum phase diagrams through classical simulation is notoriously resource-intensive, as even small systems far from the thermodynamic limit demand prohibitive computation…
Subsystem Thermalization and Work Statistical Characterizations of Floquet Dynamics
Feng-Li Lin, Ching-Yu Huang
We study Floquet thermalization in a periodically driven quantum non-integrable Ising chain by combining two operational diagnostics: subsystem thermalization and work statistics.…
Subsystem Thermalization Hypothesis in Quantum Spin Chains with Conserved Charges
Feng-Li Lin, Jhh-Jing Hong, Ching-Yu Huang
We consider the thermalization hypothesis of pure states in quantum Ising chain with symmetry, XXZ chain with symmetry, and XXX chain with symmetries. Two kind…
Space-time dual quantum Zeno effect: Interferometric engineering of open quantum system dynamics
Jhen-Dong Lin, Ching-Yu Huang, Neill Lambert +3
Superposition of trajectories, which modify quantum evolutions by superposing paths through interferometry, has been utilized to enhance various quantum communication tasks. Howeve…
Universal measurement-based quantum computation in two-dimensional SPT phases
Tzu-Chieh Wei, Ching-Yu Huang
Recent progress in characterization for gapped quantum phases has also triggered the search of universal resource for quantum computation in symmetric gapped phases. Prior works in…
Multipartite Entanglement Measures and Quantum Criticality from Matrix and Tensor Product States
Ching-Yu Huang, Feng-Li Lin
We compute the multipartite entanglement measures such as the global entanglement of various one- and two-dimensional quantum systems to probe the quantum criticality based on the…
Deterministic Dense Coding and Faithful Teleportation with Multipartite Graph States
Ching-Yu Huang, I-Ching Yu, Feng-Li Lin +1
We proposed novel schemes to perform the deterministic dense coding and faithful teleportation with multipartite graph states. We also find the sufficient and necessary condition o…
Quantum Secret Sharing with Multi-level Mutually (Un-)Biased Bases
I-Ching Yu, Feng-Li Lin, Ching-Yu Huang
We construct general schemes for multi-partite quantum secret sharing using multi-level systems, and find that the consistent conditions for valid measurements can be summarized in…
